Pendant top featuring a Mexican opal (water opal). Purchased from an acquaintance who previously ran a jewelry business for 6,500,000 yen. The opal weighs 8.09ct? 9.09ct? ... I will prepare a loupe and confirm later. Please check the size in the images. The opal is prone to scratches and is a delicate colored gemstone, so it has only been used for viewing from the case. Stored in a dehumidified storage unit. The play-of-color includes blue, sky blue, orange, red, and green, which are visible when viewed from different angles. There is no gemological report or appraisal certificate.
