Uvarovite Garnet Faceting Information

Uvarovite (Garnet) Garnet Facet

Uvarovite

Color: Emerald Green Color
Moh's Hardness: 6.5-7
Refractive Index: 1.88-1.89
Critical Angle: 32.13°
Specific Gravity: 3.77
Cleavage: Imperfect Form
Fracture: Subconchoidal mineral fracture
Heat Sensitivity: Slightly sensitive
Crystal Structure: Isometric, rhombic, dodecahedron, icositetrahedron (structure)

Possible Treatments: Generally none that I can think of

What I prefer to polishing with: Alumina oxide with a tin lap (scored).

Jeff's Comments: Very rare, seldom clean

Design Notes: Design choice is limited by the small size and inclusions, I generally cut a simple checker board that is as deep as I can cut from the rough.

Jeff R. Graham

The late Jeff Graham was a prolific faceter, creator of many original faceting designs, and the author of several highly-regarded instructional faceting books such as Gram Faceting Designs.
