These are Mariha's London Blue Topaz hook earrings. Among blue topazes, the darkest blue ones are called "London Blue Topaz." They are characterized by a mysterious, deep-sea blue color, like crystallized. The drop-shaped stones are encased in K18YG, and the combination of the deep blue and matte yellow gold is very beautiful. Purchased at a store inside Hankyu Department Store. This item was specially made for a Hankyu Department Store event and was one-of-a-kind. London Blue Topaz is considered rare in the Earth Drops and Organic Gems series. The color of the stones is truly lovely and I love these earrings because they are soothing just to look at, but I haven't had many opportunities to wear them because the hook style doesn't sit well due to the angle of my ear piercings. My tastes have also changed with age, and I don't think I will wear them in the future, so I am selling them. Accessories: Box, Guarantee Mariha has been raising prices, and the next price increase is set for September 1st. I think they are in good condition, but they are still used items, so please refrain from purchasing if you are sensitive to this. Returns and exchanges are not accepted, so please understand this beforehand. Shape: Hook/Chain earrings
