The value of a gemstone is determined by several factors.

Among all the different types of gemstones Vikings Jersey Sale , some types are more valued than others. There maybe several reasons for this valuation. The gemstone can be a very rare type of gemstone, a gemstone currently in the fashion trend or a gemstone which is more beautiful than others.

In order to grade a diamond, it is examined under a microscope having 10x magnification. Other types of gemstones are still graded by examining them with the naked eye.

Investing in gemstones should never be done. The value of most precious gems such as diamonds varies at almost a parallel rate to the economic inflation or deflation.
