  • Diamond Engagement Ring Guide
    The classic engagement ring is composed of two parts: a diamond and a setting. For the best value, focus on finding a quality diamond, as the center stone should give you the best investment, then devote the remainder of your budget to a setting that you know she’ll love. Purchasing a diamond can be a bit intimidating at first, which is why we go above and beyond in educating our clients about diamonds. Since the diamond is most of the overall cost of your ring it is essential for you to know all the details before you make a purchase.When purchasing a diamond you will also face options regarding the setting and band of the ring. There are two types of settings, prong and bezel. The band, also known as the engagement ring setting, is available in numerous styles, ranging from classic solitaire to pave settings. The band comes in varying metals including: Platinum, 14K or 18K white and 14K or 18K yellow.

  • Fancy Colored Diamonds
    Fancy DiamondsDiamonds that have a prominent body color, such as canary yellow, brown or blue are referred to as “Fancy Colored Diamonds”. All fancy colored diamonds are unique, only 1 in 10,000 diamonds is graded a fancy color by experts, like the GIA (Gemological Institute of America). Some diamond colors are much more rare and valuable than others. For example, diamonds are often found in shades of yellow and brown. But colors such as blue, pink and light green are uncommon. Deep pink is particularly rare.Investing in fancy colored diamonds has gained popularity over the past three decades. Fancy colored diamonds have significantly increased in value. Even the most conservative investors are investing in these colored beauties.Fancy diamonds are ageless and never lose their brilliance and sparkle. A fancy colored diamond is durable and transportable. It is also rare which makes it extremely valuable. For every 10,000 carats of white diamonds there is 1 carat of fancy diamonds. Investing in colored diamonds is considered a “long term investment” because it creates long-term prosperity for the investor. These rare diamonds maintain their value but appreciate greatly.
    Researchers are expecting fancy colored diamonds to triple in price in the future.The most common fancy color is yellow, while the rarest is red. Other fancy colors include blue, green, pink and orange. All fancy colored diamonds, whether yellow or red, are predicted to increase in price tremendously over the next 30 years.Investing in fancy colored diamonds is a great way to preserve your wealth.

  • The 4Cs
    For many people, a diamond is a very big purchase. With that consideration, Diamonds by Eyalrecognizes the importance of understanding exactly what you are buying. This guide simplifies the four Cs — cut, color, clarity, and carat weight.After reading this guide, you will be better prepared to choose the diamond that is right for you.

    Cut

    The Diamonds Cut The cut of a diamond determines its brilliance. There is no single measurement of a diamond that defines its cut, but rather a collection of measurements and observations that determine the relationship between a diamond’s light performance, dimensions and finish. Most gemologists consider cut the most important diamond characteristic because even if a diamond has perfect color and clarity, a diamond with a poor cut will have dulled brilliance. The width and depth can have an effect on how light travels within the diamond, and how it exits in the form of brilliance. Cut determines brilliance; however, determining a diamond’s cut grade goes beyond simple measurements of width and depth. Using an optical measuring device, a three-dimensional model is created to determine the diamond’s proportions and angles. The interrelations between these various dimensions will greatly affect how light reacts once it enters and how it behaves once it exits; by using sophisticated computer modeling, it is possible to trace light behavior and measure its levels of brightness, fire and scintillation – the face-up appearance.

    Diamond Anatomy

    Diameter: the width of the diamond as measured through the girdle. Table: the largest facet of a gemstone. Crown: the top portion of a diamond extending from the girdle to the table. Girdle: the intersection of the crown and pavilion which defines the perimeter of the diamond. Diamond AnatomyPavilion: the bottom portion of a diamond, extending from the girdle to the culet. Culet: the facet at the tip of a gemstone. The preferred culet is not visible with the unaided eye (graded “none” or “small”). Depth: the height of a gemstone measured from the culet to the table. Diamond Anatomy Cut ProportionsPolish & Symmetry affect sparkle and are two important aspects of the cutting process. The polish grade describes the smoothness of the diamond’s facets, and the symmetry grade refers to alignment of the facets. With poor polish, the surface of a facet can be dulled, and may create blurred or dulled sparkle. With poor symmetry, light can be misdirected as it enters and exits the diamond. The polish and symmetry grades are clearly listed in each diamond detail page and within the GIA or EGL diamond grading report. For the most beautiful diamond, look for a symmetry grade of ideal (ID), excellent (EX), very good (VG), or good (G). Avoid diamonds with symmetry grades of fair (F) or poor (P), as the alignment of their facets may misdirect light so severely that it affects the brilliance of the diamond. Diamond measurements are calculated and applied to a cut grading scale that makes it easy to understand how well each reflect light: Ideal cut: represents roughly the top 3% of diamond quality based on cut and reflects nearly all light that enters the diamond; an exquisite and rare cut. Very good cut: represents roughly the top 15% of diamond quality based on cut and reflects nearly as much light as the ideal cut, but for a lower price. Fair cut: represents roughly the top 35% of diamond quality based on cut. It is still a quality diamond, but a fair cut will not be as brilliant as a good cut. Poor cut: this includes all diamonds that do not meet the performance standards of a fair cut. These diamonds are generally deep and narrow or shallow and wide and tend to lose most of the light out the sides and bottom. Diamonds by Eyal carries the largest selection of certified ideal-cut diamonds. We do not carry certified diamonds with cut grades lower than good, which are generally either too shallow or too deep to present an acceptable amount of brilliance. For the best value in a brilliant diamond, choose a diamond with a cut grade of good or very good, and polish and symmetry grades of very good or good. If your diamond has an ideal- or very-good cut with very good or good polish and symmetry, you may want to consider less expensive grades of color and clarity.

    ROUND Cut Diamonds

    The round brilliant cut diamond is by far the most popular and most researched diamond shape available today. For almost 100 years, diamond cutters have been using advanced theories of light behavior and precise mathematical calculations to optimize the fire and brilliance in a round diamond. In addition to being the most popular and researched shape, a round diamond will typically give you more flexibility in terms of balancing cut, color, and clarity grades while still getting the fire and brilliance you want. To maximize the brilliance of a traditional round diamond, select one in the two highest cut grades, ideal or very good, and choose ideal, excellent, or very good polish and symmetry grades. For the finest ideal round diamonds available, call Diamonds by Eyal to speak with an educated diamond salesperson.

    CUSHION Cut Diamonds.

    This unique shape has been popular for more than a century. Cushion-cut diamonds (also known as “pillow-cut” diamonds) have rounded corners and larger facets to increase their brilliance. These larger facets highlight the diamond’s clarity, so if you choose an SI clarity grade, be sure to review the clarity plot on the diamond certificate. Cushion-cut diamonds are available in shapes ranging from square to rectangular. For a cushion-cut diamond that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.15.

    PRINCESS Cut Diamonds

    This is our most popular non-round diamond. Its beautiful brilliance and unique cut makes it a favorite for engagement rings. The princess has pointed corners and is traditionally square in shape. When choosing a color grade, consider that while the price of a J-color non-round diamond is exceptional, color may be slightly visible in its corners. Also, princess-cut diamonds can vary greatly in how square or rectangular they are. To find the dimension of princess you want, we will find the best length-to-width ratio for you in our inventory. This will determine what the diamond will look like when viewing it from above.

    EMERALD Cut Diamonds

    What makes this shape different is its pavilion, which is cut with rectangular facets to create a unique optical appearance. Due to its larger, open table, this shape highlights the clarity of a diamond. If you choose an emerald-cut with a lower clarity grade, such as SI, be sure to review the clarity plot on the diamond certificate. Also, emerald-cut diamonds can vary greatly in how rectangular they are. If you’d prefer an emerald cut with a squared outline, look for an Asscher-cut diamond.

    RADIANT Cut Diamonds

    Trimmed corners are the signature of this diamond, and they help make the radiant-cut a popular and versatile choice for jewelry. A radiant-cut looks equally beautiful set with either baguette or round side-diamonds. Radiant-cut diamonds can vary in their degree of rectangularity. The length-to-width ratio will determine the diamond’s outline, or what it will look like when viewed from the top. For a radiant diamond shape that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.10.

    PEAR Cut Diamonds

    This brilliant-cut diamond is also called a teardrop for its single point and rounded end. The unique look of the pear shape helps make it a popular choice for a variety of diamond jewelry. If you choose an elongated pear shape, the length of the diamond creates a subtle slimming effect on the fingers.

    OVAL Cut Diamonds

    An oval diamond has beautiful brilliance that’s similar to a round diamond. Oval diamonds are also very popular as their length can accentuate long, slender fingers. The length-to-width ratio will determine the diamond’s outline, or what it will look like when viewed from the top. For the most traditional oval diamonds, look for length-to-width ratios between 1.33 and 1.66.

    ASSCHER Cut Diamonds

    This beautifully unique shape is nearly identical to the emerald-cut, except that it is square. Also, this shape has a pavilion that is cut with rectangular facets in the same style as the emerald-cut. If you choose SI-clarity be sure to view the clarity plot on the diamond certificate, because this shape highlights the clarity of the diamond.

    HEART Cut Diamonds

    The heart is the ultimate symbol of love. The unique look of the heart-shaped diamond helps make it a distinctive choice for a variety of diamond jewelry. When choosing a color grade, consider that while the price of a J-color heart shaped diamond is exceptional, color may be slightly visible in its corners. To find the dimension of heart-shape you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. For a more traditional heart-shaped diamond, look for length-to-width ratios between .90 and 1.10.

    MARQUISE Cut Diamonds

    The shape of a marquise diamond can maximize carat weight; giving you a much larger-looking diamond. This brilliant-cut diamond looks beautiful set with round or pear-shaped side stones, and the length of the marquise makes fingers appear long and slender.

    Color

    Acting as a prism, a diamond can divide light into a spectrum of colors and reflect this light as colorful flashes called fire. Just as when looking through colored glass, color in a diamond will act as a filter, and will diminish the spectrum of color emitted. The less color in a diamond, the more colorful the fire, and the better the color grade. At Diamonds by Eyal, you’ll find only the finest diamonds with color graded D-K/L. Diamonds graded J or better are colorless or near-colorless — their color is typically undetectable to the unaided eye.

    Diamonds Color

    Diamond Color

    D Absolutely Colorless, the highest color grade, which is extremely rare. E Colorless, only minute traces of color can be detected by an expert gemologist, a rare diamond. F Colorless, slight color detected by an expert gemologist, but still considered a “colorless” grade, a high-quality diamond. G-H Near-Colorless, color noticeable when compared to diamonds of better grades, but these grades offer excellent value. I-J Near-Colorless, color slightly detectable, an excellent value. K-M Noticeable Color. N-Z Noticeable Color.
    Note that Diamonds by Eyal also carries fancy color diamonds. These diamonds are graded on a different color scale than white diamonds. Since the scale above ranges from the best to the worst quality in a white diamond, the colors found in fancy color diamonds are not represented on this scale.

    About Fluorescent

    Some people seek diamonds that produce this unique effect, while others avoid it. The visible effects of fluorescence grades of faint, inert, negligible, and medium, can only be detected by a trained gemologist with specific UV light. A fluorescence grade of strong or very strong can make a diamond with a near-colorless grade look even whiter. In some very rare instances a diamond with very strong fluorescence can give the diamond a slight hazy or oily appearance. For the purist, look for a colorless diamond with a grade of D-F and a fluorescence rating of faint, inert, none, or negligible. If you’d rather not compromise on color but would like to stay on budget, choose a diamond with a good cut, and good clarity, consider going with a medium fluorescence. It will still be beautiful to the unaided eye and you may prefer the unique effect of a medium fluorescence. It is imperative to come to our showroom and sit with our diamond experts in order to determine the effectiveness of fluorescence on any given diamond.

    Clarity

    Diamonds that are absolutely clear are the most sought-after and therefore the most expensive. But many diamonds have inclusions — scratches, trace minerals or other tiny characteristics that can detract from the pure beauty of the diamond. The GIA and EGL use a detailed system of rules and standards to summarize the number, location, size, and type of inclusions present in a diamond.

    Diamonds Clarity

    Diamond Clarity

    FL, IF Flawless, Internally Flawless: no internal or external flaws. Internally Flawless: no internal flaws, very rare and beautiful diamonds. VVS1, VVS2, Very, Very Slightly Included: extremely difficult to see inclusions under 10x magnification, an excellent quality diamond. VS1, VS2, Very Slightly Included: inclusions are not typically visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades, SI1, SI2, Slightly Included: inclusions are visible under 10x magnification. I1, I2, I3, Included: Will be visible to the unaided eye.

    What Clarity is best?

    We recommend that you select an “eye-clean” diamond – one that has no inclusions visible to the unaided eye. An excellent value, diamonds of this clarity are much less expensive than IF- or FL-grade diamonds and typically do not contain visible inclusions that detract from the beauty of the diamond. If you’re considering an SI grade diamond, call Diamonds by Eyal to speak to a diamond and jewelry expert who will review the diamond to ensure the quality and the inclusions. But, if you’d rather not compromise on clarity yet are budget conscious, Diamonds by Eyal will find the diamond for you.

    Carat Weight

    Once you’ve determined what cut, color, and clarity grade you’re looking for in a diamond, it’s easy to determine the carat weight of diamond that will fit within your budget. When diamonds are mined, large gems are discovered much less frequently than small ones, which make large diamonds much more valuable. In fact, diamond prices rise exponentially with carat weight. So, a 2-carat diamond of a given quality is always worth more than two 1-carat diamonds of the same quality. To choose the best carat weight of diamonds, consider her style, the size of her finger, the size of your setting, and your budget. If you have a set budget, explore all your options and at Diamonds by Eyal you’ll find that there is a wide range of diamond carat weights and qualities available in your price range. If your recipient is very active or not used to wearing jewelry, she may find herself bumping or nicking her new ring. Consider a smaller size diamond or a setting that protects a larger diamond from getting knocked against doors and counters. Also keep in mind that the smaller the finger, the larger the diamond will appear. A 1½-carat diamond solitaire looks much larger on a size 4 finger than a size 8. If you have already chosen a setting, make sure you choose a diamond to fit. Look for the diamond size specifications of your ring or ask your Diamonds by Eyal diamond and jewelry expert what size diamond you should look for. Finally, if a large carat weight is important to you, yet you’re working within a budget, please call Diamonds by Eyal to find the perfect stone for you. But the best way to determine what size is best is by getting an idea of what she is expecting. If you plan carefully, you can get some answers without even raising her suspicions.
