Precision Custom Cut Gemstones by Gary Kratochvil

More stones will be listed as soon as I get them photographed.

I do not use or agree with GIA's colored stone grading system. For the reasons I do not use the GIA system please read the article GIA Colored Stone Grading System. In my opinion a flaw is a flaw and should be graded as such. A flawless gemstone can and does occur in any material and type. For the explanation and definitions of the grading system I use please read Common Sense Gemstone Grading. If you have an interest in any stone listed use the Contact page. Thank you.

This stone has strong color zoning in the pavilion which is typical for this material. There is a very small chip in the girdle of the stone that is not visible face up and does not go into the crown. I have discounted the stone for the chip rather than recut it. The stone faces up very nice.
