Comment: Dense metallic green-blue or blue-green (depending on where you stand and the light of course). AIGS certified unheated One full carat of all-natural rich sapphire colour. Cold brilliancy running throughout the moving stone. Never black, never pale. No window, no heat. Inclusions (remarkable needles) visible only under the lens, not to the unaided eye. Good stone for a small pendant. Always good for a surprise in different light settings. Note, in the second front image and also in backside image, a glimmer of yellow shines inside the tip. Hardly visible to the quick eye but really there. Detail for the collector and unique individuality for jewelry to make sure you wear one-of-a-kind.
