Comment: For spin you may present this beautiful gem as white emerald; the gemmologist however must call it 'Goshenite' or 'white beryl'. Precision cut by David D. from an African giant rough to max brilliancy and still over ten carats. Untreated and GIA certified. Perhaps the biggest of this quality available at the time. A faint tint of blue does some magic under low light. We managed to capture a famous beryl-inclusion (called 'emerald-garden') in the magnified shot below. Yet, no inclusions are visible without lens. At 500/ct in this size, far undervalued as a precious and durable gemstone. Note also in the hand shot how the clarity of the crystal shows the skin contact with such bright clarity. Set in a pendant it may turn uninitiated heads: "OMG.... look that diamond!!!!". You: "No-no, this is a white emerald!" :-)

* This gem is on a world-tour. It may still be available but will need extra transport time. Inquire here.
