I have been looking for a 8 mm or 9 mm green sapphire. I also love any light green, or teal colors and was looking at spinel. So far I have not had any luck. I want something fairly hard so I dont have to worry about banging it up. If anyone has any Ideas please let me know.Thanks
For light green sapphire I think you should consider taking a look at Montana sapphires. They have a really nice lighter green color if it is untreated, that size might take a little bit to find though.
Would green tourmaline be too soft for your liking? Barry from acstones.com has some lovely green tourmalines available and I love his chunky cutting style.
