37.40 Ct. Orange Fire Opal (Flame Opal)

This is a truly exceptional Fire Opal, Flame Opal, weighing 37.40 carats, and its very weight tells an immediate story of premium quality and presence. Many collectors and jewelers seek stones in the single digit carat range, but this translucent rough shape piece offers a scale and substance that few opals can match. Measuring 25.53 by 24.53 by 17.37 millimeters, the stone has a substantial physical footprint that reads as both bold and refined. The cutting style is rough, with cut not applicable in the traditional sense, which preserves natural crystal faces and the raw brilliance of the material. Clarity is graded as very slightly included evaluated at eye level, so the gem is essentially eye clean while retaining the organic character that serious collectors prize. The color is vivid in intensity, an orange that reads like living flame, and the polish is excellent on the exposed surfaces, allowing light to penetrate and play within the body of the gem. There has been no enhancement, and the origin is unknown, a detail that adds to its rarity and allure.
