K18 & Platinum Ring Maximum width: 1 cm, Minimum width: 2 mm Stone (Aquamarine) size: 8 mm x 5 mm (carat unknown) Weight: Approximately 5g (measured by an amateur using a kitchen scale) Size: Approximately size 11-12 (exact size unknown) Purchased at a Mitsubishi Materials jewelry fair several years ago. The asymmetrical design and the use of gold & platinum in two colors are stylish, aren't they? There are two and one small diamonds on the left and right sides, respectively. With the price of precious metals rising, I think you don't often see a substantial ring weighing nearly 5g in jewelry shops these days. For a comparison of color intensity, I've placed it next to a white diamond ring I own. I think the stone has a sparkle, neither too dark nor too light. The last 10 photos were taken in natural light by a morning window. It has been newly polished at the shop. It appears to be in beautiful condition without any major scratches, but there may be multiple minor scratches. Those seeking perfection or who are overly concerned should refrain from purchasing. Please consider this as a used item. * Please note that the price has been changed due to the significant fluctuation and increase in the price of precious metals.
