Thank you for viewing. Please read the profile before commenting. This is a pt900 ring featuring a large 0.600ct diamond as the center stone. The color is G color, the clarity is SI2 (making inclusions difficult to see with the naked eye), and the cut is GOOD. The ring has a glamorous halo style with 0.16ct of melee diamonds and milgrain detailing, with a maximum width of approximately 11mm, giving it a sparkling presence. Milgrain detailing is also present on the arms, which are slender but solid as they are not hollowed out. Furthermore, the setting is low, making it easy to wear daily. The size is approximately size 13 on a ring sizer. A certificate from the Central Gemological Laboratory (CGL), which is considered the most rigorous in Japan, is included. (The issuing laboratory is important. Professionals and pawn shops consider the Central Gemological Laboratory, GlA, and AGT as the standards.) pt900 0.600 0.16 These markings are present.
