Choosing one
Photographs flatter and light booths lie. We choose treated black diamond in north daylight, loose, against ivory paper, and we would rather show you two honest stones than twenty pretty pictures. Diamond made opaque black by treatment. We say treated, not enhanced.
Care
Warm water, a drop of dish soap, a soft brush. Store it in its own pouch; it will scratch softer stones sooner than they scratch it.
