Made of K10, the color is champagne gold. This is a custom-made pompon ring from Parcel Jewelry. The center stone is prehnite, also known as grape stone, a pale yellowish-green stone like a muscat grape. The ring is a pompon ring surrounded by brown diamonds, yellow diamonds, and white diamonds, with a mirror-finished arm. I purchased it for 130,000 to 140,000 yen. It is a one-of-a-kind original ring. The size is 7.5. - Ring material: K10 - Stone type: Prehnite, Diamond - Stone shape: I believe it's rose cut - Ring design: Pompon ring Thank you for viewing.
