Azurite "Ocean Blue"

Gemstone Quality Standard

About Azurite "Ocean Blue"

Azurite “Ocean Blue” did come from a vein that was discovered in 2018 near Tarma in the Peruvian Andes.

The vein was fully exploited and did run dry within less than a year.

It is a mixture of azurite, malachite, and white limestone being crossed by fine brown oxidation layers. Parts of the vein also include quartz. The vein was only about 4 cm thick.

Rarity

Extremely rare. A vein (only 4 cm thick) of this material was discovered in 2018 near Tarma in the Peruvian Andes. The vein was fully exploited and did run dry within less than a year.

Polishable

Jewelry-grade material can be polished to a decent shine (because of the limestone matrix)

Premium jewelry-grade can be polished to a glass finish (because of the quartz matrix). Only the brown oxide lines may interrupt the surface polish.

Cutting Quality

Challenges:

The spiderweb of fine oxide layers make this material extremely brittle with a very high rate of loss due to breakage. This is a material for the most experienced gem cutters only.

Top-cutting-quality is characterized by:

a polished backside
a sharp rarely chipped edge between the backside and the bezel
a very straight and even highly polished bezel
a sharp unchipped edge between the bezel and the dome
a well-shaped dome, not showing any deformation
Top-quality polish

Pricing

Adequate pricing must take into account the cost factors to obtain top-quality cabochons:

Impossible to acquire more material.
High loss of material due to breakage.
A usual material loss of approximately 90 % of the material during the cutting and shaping process.
The level of experience required by a cutter to produce a flawlessly shaped and highly polished cabochon from such a brittle material.
