round - The round brilliant cut diamond is the most popular and most researched diamond shape. Diamond cutters have been using theories of light behavior and precise calculations to optimize the brilliance in a round diamond. In addition, a round diamond will naturally give you more flexibility of balancing cut, color, and clarity grades while still getting the brilliance you desire.
	princess - The Princess cut is the most popular non-round diamond. Its stunning brilliance and distinctive cut makes it preferable for engagement rings. The Princess has pointed corners and is traditionally square in shape. To some extent, the color of a Princess-cut diamond may be visible in its corners. Princess shape differs in how square or rectangular they are; the dimension of princess is in its length-to-width ratio. This will settle on what the diamond will give the impression of being like when viewing it from above.
	emerald - The Emerald-shape diamond differs from other cuts because of its pavilion, which is mold with rectangular surface to create only one of its kind visual exterior. Emerald shape highlights the clarity of a diamond. Emerald-cut diamonds can be different very much in how rectangular they are. If you'd prefer an emerald cut with a squared outline, look for an Asscher-cut diamond. To get the shape of emerald you wish for, look for the length-to-width ratio that will determine the diamond's outline, or what it will look like when viewed from the top.
	asscher - The Asscher-cut diamond shape is almost indistinguishable to the emerald-cut, with the exception of its square shape. This shape has a marquee that is cut with rectangular facets in the same approach as the emerald-cut. In choosing with its clarity, be sure to outlook the clarity plot on the diamond documentation, because this shape highlights the clearness of the diamond. The color of an Asscher-cut diamond may be visible in its corners.
	marquise - The cut of a marquise diamond can get the most out of carat weight, giving you a much superior-looking diamond. This brilliant-cut diamond looks beautiful set in the company of round or pear-shaped side stones, and the length of the marquise makes fingers come out extended and slender. To get the dimension of marquise you want, look for its length-to-width ratio because it will determine the diamond's outline, or what it will seem like when sighted from the top.
	oval - The Oval-cut diamond has stunning radiance that is comparable to a round-cut diamond. Oval diamonds are incredibly popular as their length can put the accent on long, slender fingers. To find the aspect of the Oval, look for its length-to-width ratio. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the above.
	radiant - Trimmed curve are the trade mark of this diamond, and they help make the radiant-cut and versatile preference for jewelry. Radiant-cut looks astounding with either baguette or round side-diamonds. Radiant-cut diamonds can diverge in their scale of rectangularity. To find the facet of Radiant you want, explore for its length-to-width. The length-to-width ratio will determine the diamond's outline, or what it will look like once viewed from the top.
	pear - Pear-cut diamond or is also known as Teardrop-cut diamond has a single point and rounded end. The distinctive look of the pear shape makes it trendy choice for an array of diamond trinkets. If you choose a stretched out pear shape, the length of the diamond creates a restrained slimming result on the fingers.
	heart - With its unique look, diamonds won’t just be women’s best friend. Heart-shaped diamond helps make it an exclusive choice for a diversity of diamond jewelry. Heart- shape diamond’s color possibly is slightly noticeable in its corners. To find the dimension of heart-shape you want, look for the length-to-width ratio. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top. Traditional Heart-shaped diamond has a length-to-width ratio between .90 and 1.10.

A cushion-cut diamond, is also known as a “pillow-cut” diamonds has rounded corners and bigger facets to amplify their brilliance. These larger facets highlight the diamond's clarity. Cushion-cut diamonds are available in shapes ranging from square to rectangular.

Carat Weight defines the weight, not the size, of the Diamond.

The term 'carat' is often misunderstood to mean the size of a diamond. The size of a diamond relate to the dimensions or measurement in terms of length, width and height. The carat weight is the standard unit of measure that defines the weight of a diamond

A Carat is a standard unit of weight for diamonds. Carat weights are also expressed as "points" with a one carat diamond equalling 100 points

Although diamonds are usually thought of as being colorless, they occur in all colors. A diamond can break up light into a scale of colors and reflect this light as colorful waves called fire.

Most diamonds are slightly yellow or brown, and are graded by how closely they approach colorless; the less color, the higher the value. But with fancy colors, the grade and value increase with color intensity. The less color in a diamond, the more colorful the fire, and the better the color grade.

Fancy Colors - The term fancy color to describe naturally colored diamonds with distinct, attractive tints (Artificially colored diamonds are called treated).

Diamond is a prism that can separate light into a spectrum of colors and reflect this light as vibrant flashes called fire. When looking through colored glass, color in a diamond will act as a strain, and will moderate the spectrum of color produce. The less color in a diamond, the more colorful the fire, and the better the color grade. Color greatness, the profundity or richness of color, is the most important consideration when having a fancy color diamond. The more concentrated the color, more precious the diamond will be. Fancy color diamonds are graded in order of increasing intensity from Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Dark, and Fancy Deep.

Diamond Fluorescence - The noticeable effects of fluorescence grades of faint, negligible, inert, and medium, can only be detected by a skilled gemologist with specific UV light. A fluorescence grade of strong or very strong can make a diamond with a near-colorless grade look even clearer. In some case a diamond with very strong fluorescence can give the diamond a minor haze or oily exterior. Diamonds with a very strong fluorescence are a better value for the end customer because the market prices them slightly lower than diamonds with faint or insignificant fluorescence.

Identifying Marks

Because gemstones form under unique circumstances, each gemstone is comprised of a combination of trace minerals, which create a unique set of identifying marks or inclusions. Inclusions will not necessarily detract from the beauty or desirability of a colored gemstone.

What to look for?

In considering a colored gemstone's clarity, we should measure your expectations against the standard for that variety of gemstone. Some varieties of colored gemstones, such as aquamarine, blue topaz, and citrine, have naturally fewer inclusions while other gemstones, such as emerald and ruby, might have a higher rate of acceptable inclusions. Clarity is an important factor in comparing quality colored gemstones. Even opaque opals can have milky inclusions that will effect their iridescence and color play. In general, the best values are available in gemstones that are moderately included. Exceptional gemstones with few or no inclusions are available, but they can demand extravagant prices.

Girdle diameter

- The narrow rim around the diamond separating the crown and pavilion. The girdle is parallel to the table and is the largest diameter of any part of the stone.

Table diameter

- The largest and most important facet on a round brilliant cut diamond is the table. This is the topmost facet. It is, or should be, a symmetrical octagon.

Total depth

- The Total Depth Percentage is a measure of the depth of a diamond (from the table to the culet) divided by the average diameter (width) of the girdle. The depth percentage of most diamonds is between 53 and 63 percent. This is the main factor in determining the life and brilliance of the diamond

Crown height

- The upper portion of a cut gemstone, above the girdle. The crown height describes how deep the crown is in comparison to the width of the diamond's diameter.

Thickness of the girdle

- Girdle Thickness is measured all the way around the outline of the diamond, and must be uniform and fall into thin to slightly thick. Girdle thickness outside of this range can either lead to damage, or add additional weight and cause difficulty in setting. Wide variations in thickness will cause symmetry problems.

Pavilion depth

- Pavilion depth may be judged by looking through the table (viewing the diamond from the top/crown). The best cut is indicated when the table reflection is approximately 1/3 of the table size, indicating a pavilion angle close to 40.75 degrees.

Angle of the crown facets to the plane of the girdle

Angle of the pavilion facets to the plane of the girdle

Colored gemstones are usually cut to make the most of the beauty of their color. Distinguishing quality in the cut of a gemstone, there are several points to consider.

What to look for?

A high-quality cut showcases the gemstone's color, reducing its inclusions, and display good in general symmetry and proportion. Gemstone color can vary; there are no firm geometrical standards when it comes to exploit brilliance or color. Rare gemstones are sometimes cut for size without regard for their color. For example, when corundum varieties such as sapphire and ruby are cut for maximum weight rather than beauty, they may display banded colors.

Gemstone Cut

See the gemstone in the setting and make sure that all the facets are symmetrical. An asymmetrically-cut crown indicates a gemstone of low-quality. In all cases, a well-cut gemstone is symmetrical and reflects light evenly across the surface, and the polish is smooth, without any nicks or scratches.
