All American Sapphire®
Virtually every sapphire sold in the US has been mined and cut in developing countries where working conditions and environmental regulations are weak, unenforced or nonexistent.
The new All American Sapphire® represents a road less traveled and was created for discerning customers who value domestic production, ethical mining, superior cutting and transparency.
- Every all American sapphire® has been mined, cut and polished in the USA.
- Every all American sapphire® has been at the ethically sourced from eco-friendly minds.
- Every all American sapphire® has been cut and polished with state of the art CAD/CAM robotic technology programed to produce superior brilliance.
Every All American Sapphire® has been mind in western Montana parentheses (USA) where miners must comply with numerous federal, state, and local regulations. Rules requiring complete and timely reclamation of mine acreage are strictly enforced. These enforced regulations ensures the environmental sustainability of US based Sapphire mining and contrasts sharply with most overseas sapphire production where the well documented failure to remediate abandoned mining sites is commonplace.
CAD/CAM robotic faceting
Every All American Sapphire® is preformed, faceted and polished robotically. The CAD/CAM equipment is programmed to produce exceptionally bright and lively sapphires that display maximum brilliance. This contrasts sharply with most overseas hand cutting where brilliance is sacrificed to a traditional bias that favors weight retention for the express purpose of creating illusory value. Unlike most commercial hand cutting, robotic faceting can produce more uniform outcomes. Consistent, uniform cutting perfection is what gives meaning and value to the branding of sapphires as in the All American Sapphire®.
All relevant dimensions and angles of every All American Sapphire® is measured and recorded before it is sold. This provides a customer with a unique id of each stone and documents the commitment to a very high cutting standard. The symmetry of every All American Sapphire® is measured and graded. The symmetry grades are based on the same criteria the GIA has established for the symmetry grading of diamonds.
