▶︎About Kashmir Sapphires
Kashmir sapphires are considered the highest quality blue sapphires. Depending on their size and quality, their value is exceptionally high. They were first discovered around 1881 in the Kashmir region, located on the border between India and Pakistan (northwest Himalayas), at an altitude of 4000m. However, production has gradually decreased, and it is now said that almost none are being mined. Kashmir sapphires, also known as cornflower blue, are characterized by their gentle blue hue and a silky luster throughout or in parts.

▶︎Also introduced in the gemologist quiz! Brazilian Medusa Quartz (Paraiba Quartz)
This loose stone was also introduced in the "Gemologist Quiz" on X.
It is a rare stone that features Gira-lite in Quartz (Medusa Quartz / Paraiba Quartz) with dendritic patterns, and also has the characteristics of "Tinkerbell Quartz," where the covellite glows pink when light is shined on it.
Normally, the blue gira-lite floats like a jellyfish, creating a mysterious appearance, but when light is shined on it, the covellite glows pink, creating an enchanting appearance. Furthermore, plant-like dendritic patterns can also be observed, making it a highly collectible loose stone that combines the three charms of Medusa, Tinkerbell, and Dendritic.
