ROCK TRIVIA; MOONSTONE
The shimmer of light of the moonstone is something very special in the gemstone world. The inner construction of the gemstone causes light rays to be refracted and scattered in the stone. This very unique light effect is known as 'adularisation'.
The classic moonstone, which is almost transparent with a bluish shimmer, come from Sri Lanka. However, they are also found in the USA, Brazil, Australia, Myanmar and Madagascar. For a few years, there have also been some green, brown and orange specimens on the market, as well as some with smoky and champagne colors, mainly originating from India.
Prices for Moonstone have the most astonishing range. The more intense in color, the larger and the more transparent, the more highly valued the moonstone. Bluish moonstones of good quality have been becoming more and more of a rarity in recent years and the prices for these will continue to rise exponentially.
This gemstone was very popular about a hundred years ago at the time of Art Nouveau. Pictured is a fabulous tiara from that era made by Rene Lalique with tortoise shell and moonstone.
