▶︎ About Moonstone
The charm of a moonstone lies in the optical effect known as "schiller," where light seems to emerge from within the stone. When light hits this stone, a bluish-white glow appears clearly in the center. Some gemstones sold as "blue moonstone" are mineralogically classified as peristerite or other minerals, but this is a genuine blue moonstone that qualifies as moonstone mineralogically as well.

▶︎ From Kashmir, Pakistan
This is an unheated sapphire from the Kashmir region of Pakistan. While many people associate "Kashmir" with blue sapphires, pink to purple sapphires are also found in the areas around Kashmir on the Pakistan side. This piece is appealing for its vivid pink hue with a hint of purple. It is a sapphire that is intriguing to gem enthusiasts, as it showcases the depth of the Kashmir mining origin. A GIA identification report is included.

▶︎ About Musgravite
First discovered in the Musgrave Ranges of Australia in 1967, this is a new type of gemstone that has been known for less than 50 years. Because its composition is very similar to spinel and taaffeite, it was reportedly very difficult for identification laboratories to determine until recently. It is truly a rare stone that only those in the know are aware of.

▶︎ About Kashmir Sapphire
Kashmir sapphires boast the highest quality among blue sapphires. Depending on size and quality, their value is exceptional. They were first discovered around 1881 at an altitude of 4,000 meters in the Kashmir region, located on the border of India and Pakistan (northwest Himalayas), but production has gradually declined, and it is said that they are almost no longer mined today. In addition to their gentle "cornflower blue" color, Kashmir sapphires are characterized by a silky luster present either throughout or in part of the stone.
