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.

The stone faces up very nice.
