When shopping for precious stones, it is important to keep in mind the specifications which are used to judge the quality of the stones. Diamonds and gemstones are evaluated by a universal standard that is known as the "Four C's." Cut, clarity, color, and carat weight are the most important technical features of any precious stone. A certified jewelry dealer should reveal all of this information to customers. Without specialized optical equipment, it is difficult for a person to judge a diamond or gemstone and use the Four C's standards. Additionally, a GIA certification implies that a precious stone is authentic and meets the criteria that is used to market such jewelry.

Why is a diamond considered as a gemstone?
Diamonds are costly whether they are natural or enhanced and the cost continues to rise. Diamond prices rose 30% in the last year alone. Diamond is the hardest mineral, therefore, it's perfect for jewelry of any kind, whether as a solitaire or accent stones to enhance another gemstone. Gemstone value will depend on the 4 "Cs" which are clarity, color, carat weight, and cut, in that order. A half carat diamond that is clear and colorless will be worth a lot more than a one carat diamond with imperfections and a yellowish color. However, most diamonds mined -- about 75% -- are used for industrial purposes, making gem-stone quality diamonds all the more rare.

How does the hobby-gemologist document or calculate the carat weight of various natural and lab-grown stones?
Apparently, lab-grown diamonds and mined diamonds from the earth, when cut and polished are both weighed in carats. It is important, however, to document any lab-grown stone as such.

Can any two diamonds be identical?
This is an interesting question to answer. Since a diamond gem is cut from a raw stone, and the cut shows off the best characteristics of the raw stone, in order to have identical diamonds, you'd need two raw stones that were exactly alike in their base mineral composition. Once cut, every diamond has its own unique colour, or combination of colours, carat weight, cut, and clarity. Within the clarity category alone, there are literally hundreds of variables in the location and type of flaws. Possibly, smaller stones can be closely matched according to the four Cs used to value diamonds. Matching stones precisely even as small as half a carat, becomes more and more difficult the larger the pair must be.
