Ethical mining

Peruvian Jasper is not mined. It is obtained via surface collection (Rockhounding) in very small quantities by local people who then come to Lima to sell a sack or two of those stones. There is no use of dynamite, or chemicals and habitat destruction does not occur.

Color

A mixture of white with shades of yellow, brown and green.

Polishable

Peruvian Jasper can be polished to glass finish.

Cutting Quality

Challenges:

Jasper is a very hard material, which leads to increased labor time, and increased use of tools, increasing the price of the product.

Advantages:

Jasper does not tend to break or chip. Experienced cutters therefore can obtain very sharp unchipped edges between the backside and bezel as well as between the bezel and dome.

Top-cutting-quality is characterized by:

a polished backside
a sharp unchipped 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:

Acquisition of more material is likely to be impossible.
A usual material loss of approximately 90 % of the selected material during the cutting and shaping process.
The level of experience required by a cutter to produce a flawlessly shaped and highly polished cabochon.
