Origin & story
Emerald is the green variety of beryl. Its internal 'jardin' — the garden of natural inclusions — is part of its character, and vivid saturation matters more than flawless clarity.
Zambia and Ethiopia are recognised African sources of fine emerald. SOMSTONE works with rough in matrix and cut stones, documenting each for colour, clarity type, and origin.
