Please take a moment to browse through our DiamondsHere terminology and definitions page to assist you in becoming more familiar with a comfortable amount of terminology used within the fine jewelry and gemstone industry.

At DiamondsHere, we believe in educating our clientele and providing them with current facts and information to ensure of always making the perfect purchase, and in return...acquiring jewelry and gemstones that will provide years of enjoyment!

R.B.C. Abbreviation for Round Brilliant Cut, this is an abbreviated term which can apply to all gemstones with this type of cut.

CERTIFICATION Generally applies to any 3rd (third) party grading service, which provides authentication and grading of a gemstone...a "third party" grading service can provide a true unbiased opinion, where as an "in-house" certification or appraisal may be biased.

DIAMOND EARRINGS-What you should know. One of the most common questions we hear everyday at pertains to "what should be considered a nice quality for diamond ear studs." Our opinion at DiamondsHere is simple, we recommend using the following list as a guideline when shopping for your diamond studs.

  1. CUT one can now buy beautifully cut diamonds, known within the industry as "precision cut", named so because of the new computer technology that is doing all the cutting! The new precision cut diamonds are all cut to ideal or premium proportions and display a wonderful brilliance!

  2. COLOR Choosing the right color for your diamond studs will enhance the intensity of color dispersion and the brilliance one will see when admiring the studs. The "near colorless" range for diamonds is from G color to I color, G color being the better grade of color (color ranges from D color (colorless) through N-O color/yellow). This range of diamond color provides a lovely color dispersion and will also save on the pocket book!

  3. CLARITY At we recommend clarities for your diamond ring and pendants within the SI1 to VS1 G.I.A.(tm) clarity grading scale. Nicer clarity grades will provide its owner with not only a more "sparkling/fiery" diamond, it will also lessen the risk of girdle chips or abraiding that may be inherent in lesser grade diamonds.

    Clarity grades for earrings are of equal importance, however, the industry tends to be more lenient on clarity for diamond earrings than with center diamonds for rings. At DiamondsHere, we suggest I1 or SI2 clarities for earrings, of course, one may determine the higher clarity grades are much better suited to personal taste. Diamonds that have been accurately graded in the SI2 range should not have ANY inclusions that are visible without the aid of a jeweler's loupe or other type of magnification assistance. In short, you should not see any inclusions with the naked eye!

  4. Summary Take your time and browse through our site and discover whats available in the G/H color, and SI2 clarity with the new "precision cut" technology. Secondly, for the actual diamond size or carat weight...this will be based on your budget! Happy shopping and good luck in finding your new diamond stud earrings!!!

The European Gemological Laboratories (tm) recognizes Dr. Tolkowsky's brilliant work and so denotes on the grading report when a diamond has been cut to these precise proportions.

Residing in New York City, Mr. Rapaport's company provides the industry via an annual subscription (to the trade only) a wonderful magazine full of cutting edge industry articles as well as current pricing information.

IDEAL CUT A perfectly dimensioned cut diamond...these dimensions often vary within the grading services, however, they all agree that this defined cut provides the maximum brilliance in a diamonds structure.

Comments: to a seasoned veteran of the diamond industry...CUT is first and foremost in the grading of any diamond. There are many diamond cutters and brokers that deal exclusively in "ideal" or "boutique" cuts such as "hearts and arrows(tm)" .

HEARTS & ARROWS IDEAL CUT DIAMOND The trademark of the Hearts and Arrows Ideal Cut Diamond is a magnificent sharp and crisp Hearts and Arrows pattern, an effect depicting Arrows in the top view of the diamond and Hearts from the bottom view. Found only in round cut diamonds, the effect is breath-taking and can be seen by anybody when provided with a simple gem-scope - even if you know absolutely nothing about diamonds!

MAKE: Generally refers to the shape of a gemstone and how well it has been cut.

CARAT (ct.): Word used to describe the specific weight of a diamond, for example, 1 carat = 100 pts. 1/2 carat = 0.50 pts.

KARAT (kt.): Word used to describe the specific gold content, for example we often see 10kt, 14kt, and 18kt, scientifically this is telling us that 14kt consists of .585% actual gold content.

CT. TW.: Indicates to us "total carat weight" as generally implied when we are talking about the total weight of all the diamonds in "one" particular jewelry piece.

POINT: There are 100 points in 1 carat, example 25 points = .25carats and may be referred to as a 1/4 carat diamond.

MELEE: Generally refers to diamonds or gemstones of .08 cts and smaller in carat weight, ie., .01ct. thru .08ct. in weight. These are usually what the industry will also call "accent" diamonds.

FLUORESCENCE: The property of changing the wavelength of radiation to one in the visible range; for example, the visible wavelengths emitted by a material when excited by invisible radiation (such as x-rays), as well as by certain visible wavelengths.

FLAWLESS: A gemstone or diamond absent of any inclusions within it's imperfection free, perfect clarity diamond!
