Round Diamonds

Diamond shape refers to a diamond’s physical form, and is often one of the first attributes that couples consider when shopping for a diamond. While round diamonds are the most popular choice, many couples are also drawn to the distinctive look of non-round, or “fancy shaped” diamonds. Fancy shaped diamonds include princess, cushion, emerald, asscher, radiant, oval, pear, and heart shaped diamonds. Each diamond shape has its own unique characteristics and is cut to different specifications, which impacts the overall look of the stone.

Princess Diamonds

Princess cut diamonds are the second most popular diamond shape. Princess cut diamonds possess the gorgeous sparkle of round brilliant diamonds in a distinctive square shape. They offer a contemporary look and the flexibility to work in almost any style of ring.

Cushion Diamonds

Cushion cut diamonds combine the appeal of a square cut diamond but with soft, rounded edges, lending this shape a romantic feel. This timeless shape is derived from the old mine cut, and has been refined over hundreds of years. Cushion cut diamonds are a beautiful choice for any setting style.

Emerald Diamonds

Emerald cut diamonds are treasured for their elegant silhouette. The shallow pavilion and crown accentuate the clarity of the stone, while the reflective steps enhance the color and luster of the diamond

Asscher Diamonds

The asscher cut features a square shape with cut corners. A high crown with large step cut facets bestows more brilliance than the other popular step cut shape, the emerald shape. Asscher shaped diamonds are sleek and modern in solitaire settings, and their unique shape perfectly complements vintage-inspired styles.

Pear Diamonds

Pear shapes feature a rounded edge tapering to a point at the opposite end. This unique shape flatters fingers and offers a distinctive look. A fusion of the marquise shape and the most popular round brilliant cut, pear shaped diamonds are intended to showcase the sparkle of the diamond, making it important to find a stone with great symmetry.

Radiant Diamonds

The radiant cut diamond combines the silhouette of an emerald cut diamond with the fire and sparkle of a round brilliant cut diamond. Due to its design, this shape requires more carat weight in the depth to maximize brilliance.

Oval Diamonds

The ever-flattering oval shape is symmetrical and exhibits a similar fire and brilliance to round shaped diamonds. A scintillating twist on the classic round brilliant, the elongated shape can create the illusion of larger size. Oval diamonds are highly versatile, remarkably elegant, and distinctive.

Heart Diamonds

The heart shaped diamond is an evocative signifier of true love. They shimmer with two symmetrical halves, creating a bold and romantic look. Heart shaped diamonds are especially popular in Claddagh designs, and offer a distinctive look in any engagement ring setting.

Marquise Diamonds

The marquise shaped diamond features pointed ends with a curved middle for an eye-catching look. With a larger surface area than any other diamond shape, the marquise shape maximizes perceived size and lends a unique look to any setting style.

4C's of Diamond

Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut and Carat Weight. Today, the 4C's of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world. The creation of the Diamond 4C's meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.

Anatomy

While every diamond is exclusive, all diamonds share certain essential features. A diamond’s anatomy, or its basic structure, determines its magnitudes, brilliance, scattering and sparkling. Each part of the diamond has a definite name, and having a simple understanding of how each part contributes to the diamond as a whole will help you find your flawless diamond.

Anatomy

Anatomy

A diamond is consist of the eight main components. They are Width, Table, Crown, Table Spread, Girdle, Pavilion, Depth, and Culet. Below is a brief description of each part of a diamond and its location.

  • Diameter: The width of a refined stone, measured from edge to edge.
  • Table: The largest polished facet placed on the top of the diamond.
  • Crown: The top portion of a diamond extending from the table to the girdle. The crown is made up of bezel facets (crown mains), star facets, upper girdle facets (upper halves), and a table facet.
  • Girdle: The exact edge (widest edge) of the diamond where the crown and pavilion meet.
  • Pavilion: The lowermost part of a diamond extending from the girdle down to the Culet.
  • Depth: The total height of a diamond restrained from the table to the Culet.
  • Culet: The small or pointed facet at the very Bottom-most of the diamond.

Before buying a diamond, make sure that you have a basic understanding of a diamond’s anatomy. This will permit you to truly appreciate diamonds and all their complexities, communicate with specialists about a particular diamond, and, most decisively, it will assist you in making a well-thought out decision about which diamond is best for you.

Cut

The cut of a diamond refers not to its shape, but to the balance of proportion, symmetry and polish achieved by the diamond cutter. The extent of how well the diamond is cut is directly related to the diamond’s overall beauty. When a diamond has been correctly cut, the diamond’s ability to reflect and refract light is greatly enhanced. By understanding the way that light moves through diamond crystals, modern diamond cutters have established a specific set of proportions and angles that are known to harness the diamond’s internal brilliance and to show it in its best light.

Diamond Ideal Cut

Ideal Cut

An Ideal Cut Diamond is a round, brilliant, or princess cut diamond that is cut to ideal proportions and angles, and has excellent polish and symmetry ratings. An Ideal Cut Diamond is perfectly proportioned to refract light, producing that fire and brilliance up through to the table and crown. Luxury Diamonds NYC offers a nice selection of Ideal Cut Diamonds know at True HeartsTM

GIA, considered to be one of the most respected laboratories for grading natural diamonds, uses the following language on their certificates to grade cut for round diamonds: Excellent, Very Good, Good, Fair, Poor. A GIA Excellent cut will be listed as either Ideal or Super Ideal on the site. We use specific diamond characteristics, such as cut grade, polish, and symmetry to distinguish between Ideal and Super Ideal. If a cut grade is not available from a grading laboratory, such as for fancy shaped diamonds, Luxury Diamonds NYC combines the characteristics above along with depth, table, secondary measurements, and subjective factors to assess the cut grade of the diamond.

Color

Color refers to the natural body color of a diamond and not to the reflection of spectral colors that flash when a diamond moves. Most diamonds naturally exhibit slight hints of yellow, brown, or gray. This color is caused by natural trace elements of nitrogen that were present when the diamond formed under the Earth’s crust. The less color a diamond exhibits, the higher the rarity, and therefore the higher the value.

Diamond Ideal Color

Diamond Color

Color of a diamond is a result of diamond’s composition and does not change with time. Colorless diamonds allow light to travel through them as compared to the colored diamonds. These diamonds also emit more fire and sparkle. The process, through which a diamond is formed, is the deciding factor for its color. The whiter the diamond is the higher value it will have. For grading the color of diamonds, jewelers refer to GIA’s color scale that starts the rating with D for the colorless diamonds and grows up to Z as the traces of light yellow or brown color are found in the diamond. Diamonds graded from D to F are amongst the most desirable and valuable stones. These diamonds are a delight for the diamond lovers. Nevertheless, if you have a low budget, you can also find good diamonds with lower grades. These diamonds are not exactly colorless but show no color to untrained eye.

Clarity

Clarity refers to how clean or clear the diamond is with respect to natural microscopic characteristics that were trapped within or on the diamond while it was forming. Internal characteristics are known as inclusions, and characteristics on the surface of the gem are known as blemishes. Inclusions may be crystals of a foreign material or structural imperfections such as tiny cracks, known as feathers, which can appear whitish or cloudy.

Carat

Carat (ct.) refers to the unique unit of weight measurement used exclusively to weigh gems and diamonds. Carat weight is often confused with visual size even though it is actually a measurement of weight. Depending on the shape and type of gemstone being weighed, the weight will visually show itself differently. For example, a 1.00 ct. round diamond will measure around 6.5mm, and a 1.00 ct. round sapphire will measure around 6.0mm. This is due to the varying density of different gemstones.

Diamond Certification

What is a Diamond Certificate?

A diamond certificate verifies each diamond’s specifications, including its color grade, carat weight, clarity grade and cut grade. You should never buy a diamond without a diamond certificate. The most well-known grading laboratories are the Gemological Institute of America (GIA) and the American Gem Society (AGS) and the International Gemological Institute (IGI).

A diamond's cost depends upon objective characteristics popularly known as the 4C's: Color, Clarity, Cut and Carat. The relationship between these four characteristics determines the value of a diamond. Although it is commonly assumed that carat is the most important member of the 4C's, color, cut and clarity have a much greater impact on the appearance of a diamond.

Diamond Care

Depending on the setting you choose, you can soak your diamond engagement and/or wedding rings for up to 30 minutes in a solution of dish washing liquid and water. This is best suited to prong and cathedral settings. In pave and basket settings, however, soaking the rings can increase the likelihood of the gems coming loose. Be mindful of this when you decide to soak any jewelry piece use mild dish soap in warm water and soak your jewelry for a few minutes. Using a soft cloth or cotton swab, gently scrub the metal (gold, platinum, silver) and then rinse. Repeat the process if necessary, but always proceed with caution when it comes to soaking jewelry.

Diamond Care

Cleaning your Diamond Jewelry

You can use toothpicks to remove dirt that is lodged in between the prongs and the diamonds, but be extra careful not to scratch the metal or move the positioning of a prong. If fibers from cloth get stuck in the setting, gently use tweezers to remove them. Again, be careful of the metal. Even though diamonds can only be scratched by other diamonds, the precious metals into which they are set can be scratched more easily.

When storing your diamond jewelry, be sure to keep it separate from other jewelry. Remember that diamonds can not only scratch any other jewelry you have, but can scratch each other as well. Make sure that two diamond pieces are not being stored in such a way that they touch each other.

Gemstones - Clarity

Clarity

The clarity of a gemstone refers to its internal and external flaws. The fewer inclusions it will contain, the better grading it will have, and the more valuable the colored stone will be. The clarity of a gemstone depends on its type. Very clear stones are graded- AAA clarity, and semi clean stones are of AA clarity. Some gemstones of the highest possible quality are graded- AAAA.

Tiny crystals of a mineral, small gas bubbles, minute liquid filled pockets, internal fractures or cleavages, or any other matter visible inside the stone is an inclusion. Any external factors like scratches, abrasions, chips or spots are blemishes.

The cost of a diamond is highly affected by inclusion. Some flaws in a gemstone are even visible to the eye. Gemstone grading is not as rigid as diamond grading.

Gemstones - Cut

Cut

The cut is one of the most important elements in determining the value of a gemstone. The shape of a diamond is its cut. There are various gemstone shapes available like rounds, ovals, hearts, marquise, cushions, pears, emerald or octagonal cut hexagons, half-moons, triangles, and carved gems. A gemstone is graded in four levels- excellent, very good, good, and fair. An excellent cut will reflect on a gemstone's quality. The excellent cut has minimum visible inclusions and extremely deep color that increases its overall visual appearance.

Achieving l00% brilliance may not be the final goal of cutting gemstones. Several variables affect the cut of colored stone. If a gemstone is too dark, it is cut shallow, and a shallow cut provides a better color to the gemstones. Deep color can also affect the brilliance of a gemstone as light is absorbed rather than being reflected in extremely dark colored stones. When it comes to very light-coloured stones, the cut is very deep to enhance the overall color of the gemstone.

Gemstones - Color

Color (Hue-tone-saturation)

Each gemstone has a unique distinguishing color. Color is a crucial factor that affects the price of a colored stone. For better analysis, it is essential to understand different color parameters. A gemstone says sapphire can have a different color intensity, shade, purity, saturation and tone. Hue, tone and saturation are three main parameters used for determining the color of a gemstone.

Hue represents the primary color of the gemstone. Identifying hues is very easy. The tone of the colored stone helps identify the intensity of the color from light to dark. Ideally, some color tones look more appealing than others as per the design and the setting of the jewelry. This can vary at times depending on a person’s taste and preference.

Saturation describes the intensity of the color present, that is, how much color there is. The most expensive gemstones have the most color saturation. The price of a colored stone can fall if the saturation is low. The brighter the emerald (green), the higher the price.

Gemstones - Carat Weight

Carat Weight (Size)

Carat is the unit of measurement used for weighing a gemstone. Carat weight is one-fifth of a gram, which is 0.2 grams. One-fifth of a gram would be the weight of a paperclip. Carat should not be confused with karat (10K, 18K), which refers to the purity of gold. Nowadays, gemstones are weighed using an electronic digital scale. There are a variety of stones available in the market, and all these colored stones possess different densities (mass per unit amount). Two similar-sized, identical gemstones might differ in their weights.
