[QUOTE="silver, post: 403982, member: 1953"] Star could not be seen in the amethist even if a lighter colour because the refractive index for both will be different within the stone.... not that I would know Lefty.... they all still look great mate..... but.... if you study your RI's and make mathematical adjustments on your grind plans I'm sure you of all people (as well as a few others) would be able to achieve the impossible and create a new vision of possibilities beyond popular consensus within the full spectrum of gemstones ya currently playing with.... ie:- gemstones + RI knowledge angular mathematical equations = new pretty stones. Now if you keep your maths to yourself and were able to patent your designs would they then be worth money somehow in the right hands ? :Y: [/QUOTE]
