The mineral
Beryl colored by chromium or vanadium. Softer than corundum, and greener than anything else the ground produces.
In the hand
At 7.5 / 10 on the Mohs scale it is everyday-hard with sense: fine for daily wear, taken off for the gym and the garden.
Treatment, plainly
Untreated unless its passport says otherwise. When a stone of ours is heated, the passport says heated, in that word, and the price reflects it.
Choosing one
Photographs flatter and light booths lie. We choose emerald in north daylight, loose, against ivory paper, and we would rather show you two honest stones than twenty pretty pictures. Beryl with chromium in its bones, the green all others are measured against.
Care
Warm water and a soft cloth, nothing ultrasonic. Store it in its own pouch, away from harder stones, and bring it to the studio once a year; the check costs nothing.
