One 30.55 carats trilliant cut amethyst, reddish violet to purple color, VS+ clarity, cut grade excellent, measuring 21.7 mm wide, 21.7 mm long, 14 mm deep; with very good polish and excellent symmetry. The proportions of the amethyst are as follows: total depth 64.5%, table width 55%, and a girdle thickness of medium to thick. The amethyst also has a crown angle of 40° and a pavilion angle of 43°. Brilliant style pavillion with a stepped crown. This exceptional amethyst is from the 2015 discovery of amethyst in Rwanda a country to the north of Tanzania. This is as fine of material as I have ever seen. I have cut material from Zambia, Uraquay, Madagascar, Brazil but none have displayed the dramatic color shift that this fine amethyst exhibits. This is a great example of what we know as Siberian color and I would venture to say in the future we will use Rwanda color as the standard all amethysts will be compared. This stone was at first a great disappointment. After cutting it takes a day or two to remove the glue that holds the amethyst to the faceting dop stick. I took the solvent jar and amethyst home over Fathers Day weekend as I was excited to see what I was sure would be an exceptional gem amethyst. When it was finally freed, I removed it from the solvent and it was a total disappointment. Over dark and a muddy reddish violet color. Slightly depressed I went to the garden as to not think about it. I knew there was still hope as this stone was not heated and heat can lighten dark amethyst. This material from Rwanda is unusual as all amethyst I have purchased in the rough from other sources was heated already to lighten the color. Once back to work I put it in the kiln and there was little fear of heat damage as the stone was completely clean or free of inclusions. The next day I removed the amethyst from the kiln as I was rewarded with a amethyst gemstone that was better than I could have hoped for, bright and vivid colors with that color shift that is so dramatic from a rich reddish violet in incandescent light to blueish purple in florescent and a mix of the colors in diffused daylight. A true beauty in all lights. This gem was precision cut by Marsha Tokarski in our shop and took over 10 hours to cut and polish. This loose amethyst is among the finest in the world displaying not only outstanding colors but it has excellent brilliance which is rare in gems of this deep color.
