[On sale August 27, 10 PM JST] Brazilian blue tourmaline, 1.566 ct, loose, with appraisal

Tourmaline is known as a treasure trove of colors. Its etymology is the Sinhala word "tourmali," meaning "various colors." Among these, blue ones are called "blue tourmaline." Tourmaline makes you want to collect all the different colors.

This is a highly transparent green-blue tourmaline from Brazil. Its charm lies in the deep color, as if blue and green have melted into one another. It is so clear that it is difficult to find inclusions even with a loupe, allowing you to enjoy its high transparency. An appraisal report is included.
