A very rare cut stone of phosphate mineral!
Green Herderite 3.31ct

RECOMMENDED POINTS
This is a rare green-colored herderite that is attracting attention from collectors.

Herderite is a rare stone that is known only to those in the know.

It is a rare gemstone for collectors, as it is produced in small quantities and is difficult to find even in mineral encyclopedias.

It was discovered in 1825 in the tin mines of Ehrenfriedersdorf in the Saxony region of Germany, and was named after the mine's director at the time, Von It is named after Baron Herder.

Herderite is based on the mineral beryllium.

Famous gemstones made up of beryllium include the beryl group, which includes emeralds and aquamarines.

Herderite is a "phosphate mineral" that contains calcium and beryllium, and there are very few of these minerals in the world, so it is inevitable that gem-quality stones that can be cut are extremely rare.

Furthermore, the basic color of herderite is colorless or yellowish, so a bright green color is very rare.

Furthermore, faceted stones over 3 carats are rarely seen in Japan.

This is a rare stone that we rarely have the opportunity to introduce, so please take a look.
