Purchased at Isetan Shinjuku Main Store for 420,000 yen. Given the current rise in prices for both the metal and diamonds, I believe it would be difficult to purchase at this price now. The diamonds are beautiful. They sparkle with a rainbow effect. The main diamond is princess cut (square), surrounded by small round cut diamonds. It's a mystery setting. Even the small melee diamonds are a beautiful feature of this item. It shines beautifully with a rainbow effect under the downlights of hotel bars, restaurants, and concerts, but it's not too large, so you can wear it with a t-shirt and jeans. It's a timeless design.
