Gemstone Quality Symbols at EuroGem.biz

Clarity

Clarity is defined as the degree to which the stone is free of inclusions. Unlike a shape, size or weight, the factor of clarity is not as easy to determine. Clarity ranges from gemstones which appear perfect under a 10X magnifier (FI / Clean or EC / Eye-Clean) to those which show a major number of flaws to the unaided eye. The more expensive the gemstone type, the more clarity faults or flaws are acceptable. An emerald with flaws visible to the unaided eye is acceptable, but a garnet with such flaws might not be acceptable.

Below you will see a scale which defines clarity grading of gemstones at EuroGem.biz:

Color

Like clarity, color factor is also quite difficult to determine because it applies according to stone, like all colorless gemstones such as white topaz should be as colorless as possible and colored gemstone should have that color as rich as possible. In almost all cases of faceted, colored gemstones, the color should be as deep as possible.

Cutting & Finishing

In faceted gemstones there are many different cuts like Diamond cut (round, brillant), Checker Board cut, Princess cut, Step cut and there are many other cuts which have been used. For very valuable gemstones like diamonds, a perfect cut is one of the most necessary quality features and depends on the skills of the cutter.

There is no standardized scale to explain the cutting and finishing of colored gemstones but we have tried to explain our standard of cutting and finishing of gemstones through our numeric scale below:
