Color stone reference table

◆◇◆ Color stone quality and hue ◆◇◆

Transparency and inclusions that are difficult to understand only with images of colored stones,
We classify quality and beauty according to Jewel Climb's own grading standards,
We introduce a wide variety of colored stones in an easy-to-understand manner in terms of types and numbers.

quality F. A quality that makes it difficult to see the inclusions with a 10x loupe.
*Because it is a natural stone, there are minute inclusions.
VS A quality that makes it difficult to see the inclusions with the naked eye.
*In the case of gemstones that take in a lot of inclusions, it is minor.
SI Quality that allows inclusions to be seen with the naked eye.
* Including fine chips and scratches that are difficult to see with the naked eye and lack of fabric
Color stone inclusions are a proof of nature.
There are stones that always contain inclusions depending on the type of gemstone.
≪Notice≫
Because cabochon cut, cat's eye, and star type loose cabochons are generally not polished on the back (back side),
There are dents, etc. Our quality evaluation evaluates only the polished top part.


hue S. Top-class colors for the gem type or colors that are not found in abundance
A. A color of quality that falls within the beautiful or fine class of the gemstone species
B. A color of the quality commonly found in the gemstone species
The hue of colored stones is evaluated differently depending on your preference.
It is evaluated based on the hue that tends to be generally traded highly.

Color stones do not rely on absolute grade values,
There are many things to choose from based on personal taste.

Also, even if there are inclusions that are proof of nature, there are many loose pieces that look beautiful.

When choosing a colored stone, don't be misled by the evaluation alone.
We recommend that you choose a color stone that you like.


【please note】
This grade standard is our own standard and is determined by comparison with the top grade loose that is generally available. This notation is completely different from the standard for diamonds. It also differs from other companies' standards. It is a reference evaluation when considering colored stones introduced on the shopping page based on our purchase experience of "Jewel Climb".
