Its length x width x depth of a diamond in mm.


A scratch or abrasion on the surface of a diamond.


Also referred to as Fire or luster. The light that has entered the diamond through the crown and is divided into white and colored light, from bouncing off the diamond’s facets, and exits back through the crown creating what’s called sparkle.

The effect of brilliance is a combination of cut and proper proportions.

 Brilliance Cut

The most common style of diamond cutting; which includes any cut with 58 facets. Round, oval, radiant (square), pear, or heart shaped diamonds can be cut using this technique.


A unit of weight for a diamond. Equivalent to 200 milligrams, or one-fifth of a gram.


It’s a grading given to a diamond to describe the level of "impurities" or inclusions.

 Clarity grades include

  • FL = Flawless -- no internal or external inclusions of any kind visible under 10x magnification to a trained eye, the most rare and expensive of all clarity grades
  • IF = Internally Flawless -- no internal inclusions visible under 10x magnification to a trained eye, but there may be some tiny external irregularities in the finish
  • VVS-1 = Very Very Slightly Included 1 -- usually just one tiny inclusion visible only to a trained eye under 10x magnification
  • VVS-2 = Very Very Slightly Included 2 -- tiny inclusions visible only to a trained eye under 10x magnification
  • VS-1 = Very Slightly Included 1 -- very small inclusions visible with 10x magnification
  • VS-2 = Very Slightly Included 2 -- several very small inclusions visible with 10x magnification
  • SI-1 = Slightly Included 1 -- small inclusions visible with 10x magnification
  • SI-2 = Slightly Included 2 -- several small inclusions visible with 10x magnification
  • SI-3 = Slightly Included 3 -- inclusions that may be visible to the naked eye for a trained observer
  • I-1 = Included 1 -- flaws that are visible to the naked eye
  • I-2 = Included 2 -- many flaws clearly visible to the naked eye that also decrease the brilliance
  • I-3 = Included 3 -- many flaws clearly visible to the naked eye which decrease the brilliance and compromise the structure of the diamond, making it more easily cracked or chipped


The breakage of stones along planes of atomic weakness related to the internal arrangement of atoms.


Clouds are hazy or milky areas made up of tiny pinpoints inside a diamond. Most clouds are made up of crystals too tiny to see individually under a loupe. Clouds are typically hard to find in diamonds with high clarity grades. When clouds are large and dense, they diminish transparency and can make a diamond look undesirably white.


A grade given to a diamond to describe the subtle tones of color in a stone. D is perfectly colorless, the most rare and expensive color. As you go from D to Z on the normal color scale, it indicates increasing levels of yellow and/or brown tones. It takes a trained eye under special lighting to distinguish between neighboring color grades (such as E to F), but most people can discern the difference between colors that are several grades apart (such as E to H) with a little practice.

  • D, E, F = Colorless
  • G, H, I, J = Near Colorless
  • K, L, M = Faint Yellow
  • N, O, P, Q, R = Very Light Yellow
  • S, T, U, V, W, X, Y, Z = Light Yellow


A facet on the very bottom of a diamond. It is best to have a small or medium culet. A large culet will make it look like there is a hole in the bottom of the stone due to leakage of light.


Commonly used to refer to both the shape of a stone (round, pear, oval, etc.) and the make (the exact geometric proportions to which a diamond is cut). The make of a stone is the most important factor in determining how much sparkle comes from a diamond, regardless of the shape.

  • Ideal Cut : Round diamonds that is perfectly proportioned (having depth percentages and table percentages that produce a "perfect" balance of fire and brilliance). Ideal Cut diamonds are usually more expensive than all other cut grades. This is due to three major factors: 1) extra time and skill are required to cut to such precision; 2) they are in great demand, and perhaps most importantly, 3) more of the original rough diamond must be sacrificed to achieve ideal proportions.
  • Very Good Cut : Diamonds cut to fit very strict requirements for depth percentage and table percentage. These outstanding proportions maximize fire and brilliance in the diamond.
  • Good Cut : Diamonds cut with acceptable, but not perfect, proportions. They generally have very good brilliance and fire and make excellent jewelry.
  • Fair Cut : Diamonds cut to less perfect proportions. They have been cut to maximize the weight of the stone, and sacrifice fire and brilliance. While less expensive than diamonds shown as having Good and Very Good cuts, they do not have the brilliance and scintillation (sparkle) people expect from a diamond.
  • Poor Cut : Poorly cut diamonds with proportions and finish that make them look relatively lifeless to the eye. We do not recommend such stones for fine jewelry.

 Certified Diamond

A diamond with grading report that defines the physical characteristics and quality rating of that Diamond is called as Certified Diamond. These reports are given by reputed and recognized laboratories like GIA, HRD, IGI etc.

 Diamond grade

Diamond grading is a system devised to classify the color, clarity, cut and carat weight of a diamond. The Gemological Institute of America (G.I.A.) developed a system that is the most respected, and is the standard used by most jewelers.

 Diamond gauge

An instrument that is used to measure a diamond's length, width and depth in millimeters.


The height of a diamond (measured from the culet at the very bottom to the large table facet on the top).

 Depth %

The height of a diamond (measured from the culet to the table) divided by the width of the diamond. The depth % is critical to creating brilliance and fire in a diamond. A depth % that is too low or too high will cause light to leak out of the stone, causing the diamond to lose sparkle.

 Eight cut

A gemstone which is faceted with 16 facets, 8 on the top and 8 on the bottom. It is primarily used for small stones.


A diamond that has no inclusions visible to the naked eye -- flawless to the naked eye. This is normally true of all diamonds with a grade of about SI-1 or higher on the clarity scale.


The polished flat surfaces on a diamond. For example, a round brilliant diamond has 58 facets when counting the culet.

 Fancy cut

A gemstone cut into a shape other than round. Fancy cuts include princess, pear, marquise, oval, baguette, emerald, heart and less common but very unique shapes such as stars


A glow, usually of a bluish color, which emanates from certain diamonds when exposed to ultraviolet light. Strong fluorescence should be avoided, but faint fluorescence usually does not affect the appearance of a diamond. In fact, faint or moderate blue fluorescence is preferred by some customers because it can make a less expensive yellowish color appear more white or colorless in daylight.

 Four C’s

An abbreviation used to describe the Color, Clarity, Carat and Cut of a gemstone as defined by the G.I.A. which created a Diamond grading system using the 4C's.


The Gemological Institute of America ( G.I.A.) is a highly respected, not for profit organization, devoted to the promotion of education and ethics within the jewelry industry. G.I.A. also has a laboratory used to grade and identify gemstones.


The narrow band around the widest part of a diamond. The purpose of the girdle is to protect the edge of the stone from chipping. When the stone is placed in a setting the jewelry usually grasps around the girdle.

 HRD Definition

The Diamond High Council (Hoge Raad voor Diamant) is a non-profit organization at the service of the Belgium diamond trade and industry. HRD, is the world's foremost authority in gemology and famous in diamond grading certification.


An impurity within a diamond, such as a spot or irregularity in the crystal structure of the stone. These can include a cloud, a fracture, another diamond inside the bigger one, liquid, etc. Inclusions can either be visible with the naked eye (usually SI-3 clarity and below) or visible only under magnification. Fewer inclusions means a finer clarity grade, increased rarity, and increased value.

 IGI Definition

Stands for the "International Gemological Institute". It is the independent gem certification and appraisal service provider. It offers Diamond Grading, Diamond Certification and Diamond Appraisals.

The quality of the finish and proportions of a finished diamond. A good make will have proportions that maximize brilliance and fire. A poor make will decrease sparkle and fire due to the loss of light as it travels through the stone.

 Moh’s scale

The measure of a mineral's hardness in relation to other minerals, based on its ability to resist scratching. The scale goes from 1 to 10 where diamonds are a 10 and talc is a one. Most colored gemstones fall in the 6 to 9 range on the scale.

 Non certified Diamond

A diamond with no grading report by any reputed laboratory but carry in-house report by company that defines the physical characteristics and quality rating of a Diamond is normally termed as Non Certified Diamonds. Non Certified Diamonds can be certified on customers demand.

 Pay Pal Definition

PayPal is a Web-based application for the secure transfer of funds between member accounts. PayPal serves as an electronic alternative to traditional paper methods such as cheques and money orders.


The bottom of a diamond, everything below the diamond’s girdle.


A measure of diamond weight. One point equals 1/100th of a carat. A diamond that weighs 0.50 carat is said to weigh 50 points. This does not refer to the number of facets.


Polish refers to how smooth the facets of a diamond have been polished by the polishing wheel. Polish influences how well light is able to pass through a diamond and is very important to a diamond's brilliance. It is highly recommended that one select a diamond that is laboratory certified with a Good (G), Very Good (VG), Excellent (EX) or Ideal (ID) polish. Diamonds that have Fair (F) or Poor (P) polish are less brilliant because they have microscopic polish lines that blur the surface of the diamond. These polish lines reduce the amount of light that enters or exits a diamond.


Round Cut Round in shape made up of 58 facets
Princess cut A modification of a brilliant square-cut gemstone
Marquise shape Its oval shape with tapered ends
Pear shape The pear shaped diamond, also called a teardrop, is a hybrid combining the most remarkable characteristics of oval and marquise shaped diamonds
Radiant shape Square shaped and with trimmed corners, to enhance brilliance, the radiant shaped diamond is a beautiful combination of the emerald and round diamond shapes.
Heart shape Cut in the shape 0f heart
Oval cut The oval cut is most similar a round-brilliant cut and combines the round's sparkle with a flattering, elongated outline
Emerald cut A style of faceting that creates a rectangular gemstone, usually with cut corners to prevent chipping
Asscher cut Square step cut with cropped corners.


The combination of fire (dispersion) and brilliance. The amount of light that reflects out of a diamond as it moves.


A diamond's symmetry is graded according to how precisely the facets are aligned. That is, the top of the facet should align with the bottom of the facet.


The large flat facet on the top a diamond. If the table facet is too large or too small, it will often indicate poor proportions overall. Poor proportions will hurt a diamond's fire and brilliance.

 Table percentage

The width of the table divided by the diameter of the diamond. The table percentage is critical to creating sparkle in a gemstone; a diamond with a table percentage too low or too high will lack sparkle.
