What You Need to Know About Loose Diamonds
Diamonds that have not been placed in a setting are referred to as loose diamonds, and are generally sought after by investors and professional retail jewelers. Any purchase of loose diamonds should be accompanied by a certificate of appraisal and value.
The certification, which should always be based on an appraisal and analysis done by an outside, independent third-party agency, is more properly known as a diamond grading report. This report describes your loose diamonds in terms of weight in carats, clarity of the gems, color and cut. The individuals who perform this service are known as gemologists, and have received specialized training in this particular sub-field of geology. Gemology focuses on the study and analysis of precious stones and gems.
When loose diamonds are accompanied by such a report, they are known as certified. Anyone considering an investment in such diamonds, whether they are for use in diamond jewelry or as a hedge against inflation should make sure that their purchase consists of certified loose diamonds.
The job of a gemologist's certification is not to assign a monetary value on loose diamonds; that happens in the marketplace. However, such a report is used to determine such a value. The weight in carats (a carat is roughly equivalent to .015 of an ounce, or two-tenths of a gram) is the most obvious basis of valuation; however, if the gem has a "cottony" appearance inside, this can affect the value negatively.
Certified diamonds are evaluated on what are known as the SI3 Clarity Scale and the Color Scale. The Clarity Scale was developed by the Gemological Institute of America (GIA); it ranges from "FL" for "flawless" to I3 for "Imperfect," i.e., cracks and occlusions easily seen by the unaided eye.
Colored diamonds are rated on a scale that describes the gems in terms of hue and saturation. They are labeled with a letter of the alphabet from D to Z, ranging from virtually colorless to gems with a deep hue. Diamonds can be almost any color; the color variations include pink, green, blue, purple and amber, and are caused by chemical reactions during the diamonds' formation. Such gems can be worth substantially more than "white," or clear diamonds.
Control of the diamond market is concentrated in relatively few hands, centered around Antwerp, Belgium, where the diamond cutting industry was born over 500 years ago. These wholesalers recommend that diamonds be certified either by the GIA or the American Gem Society Laboratories.
Because of the way the analysis is done, it is impossible to perform a certification on mounted stones; loose diamonds should be certified prior to placement in a setting, ring, or watch, and the seller should provide documentation that such services have been performed.

How can red sox fans attack a rod for trying to knock the ball loose at first base but cheer mike lowes?
attempt to tackle cano
i am not talking about his takeout of doug w/e his last name is (i have no chance of spelling it right) he couldnt of stopped himself but earlier in the game cano was turning a double play and lowe rammed into him when he could easily have gotten out of the way
i understand that lowell play was legal had he not raised his elbow to canos neck if he had ran into him probably wouldnt care but he did raise the elbow and could have caused more damage
Because it's OK for the Red Sox to play dirty, but no one can do the same to them. If anyone remembers, Dice-K hit Jeter and A-Rod the first time they faced Boston in April, but the Yankees didn't retaliate. Then Boston hit three more Yankees Friday night, including Cano intentionally after he had hit a home run. But when Boston players are hit, WOW, do they ever get mad. They can dish it out, but they can't take it.
Boston players and fans think it's alright for their team to get down and dirty. It's OK for their pitchers to throw at Yankee hitters, and for Lowell to knock Cano down, but when A-Rod slid into Pedroia, he cried like a baby. I used to like Lowell a lot, I remember when he came up to the Yankees in 1998, but like a lot of guys who are traded to the Red Sox, he became an idiot, like Schilling, when he put that uniform on.
To answer your question, I think the Red Sox think they have the right to play dirty, but no one else does. Consider this, when Youkilis was hit, he was yelling and screaming, but when A-Rod was hit by Arroyo three years ago (after he had homered the night before), he took offense and got a glove in the face from Coward Varitek, who was hiding behind a mask.
