The Girdle of a Polished Diamond

Buying a Diamond Ring is important and it pays to get a Diamond that really sparkles.  Have you ever wonder what the words “diamond girdle” means, when you see it mentioned on a GIA diamond certificate or grading report?Well, the girdle is exactly what it implies (;-), the outer most circumference or rim of a diamond.  Some diamond girdles are polished, which is where the diamond cutter actually creates facets around the girdle.  Other Girdles, are left in their natural, or unpolished state, which appears grayish and lack the sparkle.  Girdles come in different sizes, Thin – Medium – Thick as well as extreme sub-measurements of these like extremely thin and extremely thick.  An extremely thick girdle is often applied to maintain carat weight and push the diamond into a key price bracket such as 1.00 carat.  If this same diamond was cut to ideal proportions it would maybe become a 0.95 carat.  The thick girdles therefore influence the depth percentage of a diamond.  A very thin Girdle can be brittle and proce to chipping.  We therefore recommend a Girdle that is thin to medium.  For further information about Girdles and how to pick the perfect diamond visit our website at www.polisheddiamonds.us or view our selection of loose diamonds.  Purchasing a loose diamond or a diamond ring is important and it pays to get it right first time – use our help to get it right!

Fluorescence in Diamonds – Polished Diamonds

If a diamond has fluorescence in it, than you will be able to see it inside the diamond when the diamond is exposed to Ultraviolent Light (UV Light). The sun also emits some UV Light. A fluorescent diamond exposed to UV Light will emit a glow, this glow can appear in the form of a blue glow or it might also be a yellowish glow, although it is rare there have been diamonds which have a red glow as well.

Keep in mind that there is a difference between a diamond which is cloudy and a diamond that is fluorescent. A diamond which appears cloudy may be due to its clarity, but it doesn’t necessarily mean that the diamond is fluorescent. There are many fluorescent diamonds which are absolutely transparent in appearance. Diamond that have Extreme and Strong fluorescence may impact on clarity and should be checked for the face up beauty of the stone.

A diamond which emits a yellowish glow will devalue that particular diamond’s value, for some lower color grade diamonds having some fluorescence may add to its value often making it appear more colorless, the diamond will appear whiter when it is worn outside particularly where there is a lot of sunlight.  The general rule of thumb when appraising a fluorescent diamond is that it will negatively impact the price of the diamond. Since some diamonds with fluorescent attributes can make the diamond appear more colorless, the best way to judge the diamond’s color is to look at the diamond under a filtered lighting source, removing all remnants of UV Light will help you see the diamond for its true color.

Don’t let a sales rep trick you into paying more for a fluorescent diamond, they may try to pass off a higher quality colour, they will speak about the lovely glow that the diamond emits and how much whiter the diamond is, but the truth is that the diamond has a little faint yellow in it. Remember, you will be wearing the diamond in all sorts of environments and not all of them will have UV Lighting, so although a diamond which has fluorescence is not a bad diamond, only purchase the diamond if you are satisfied with the diamond after inspecting it under normal lighting conditions, and leave the fancy UV Lighting for cocktail parties.   Visit www.polisheddiamonds.us for more interesting diamond information and for diamond rings see http://polisheddiamonds.us/diamond-rings-usa-c-2.html .
