Before purchasing any fine colored gemstone there are things you should know besides just the weight, the beauty, and the price that you are going to pay. So that you do not make a costly mistake, it will be worth your while to work with an AGS Certified Gemologist to help you make your decision.
If a colored gemstone is desirable and has significant value, you can be sure that there is a synthetic counterpart to that gemstone available in the marketplace. Synthetic does not mean just a look-alike gemstone, although there are those as well.
Synthetic means that the laboratory-grown gem is a chemical and crystalline duplicate of the natural gemstone, and usually it takes a gemologist, with the aide of special gemological equipment to determine the difference. Synthetics have natural looking inclusions, which resemble those found in their natural counterpart.
