I purchased these last year at Tsutsumi in Shibuya. K10 Yellow Gold London Blue Topaz Earrings 26,000 yen These colorful earrings combine pear-shaped London blue topaz with oval-cut sky blue topaz. These earrings, where the colored stones take center stage, will make you feel happy just by wearing them. They are also recommended as a stylish accent. Metal Material: K10YG Gemstones Used: London Blue Topaz, Sky Blue Topaz, White Topaz Size (length x width): Approximately 31 x 5mm Please read my profile before purchasing.
