Currently, yellow gold is available as a current product, but the rose platinum material is no longer sold, so I think it's rare. The fifth photo is of the current yellow gold product. The item will be delivered as a necklace only, but for an additional 500 yen, it will be delivered in a SIENA ROSE box. [Size] Inner circumference: shortest 38.5cm, longest 41.5cm Motif: 0.17cm long x 1.6cm wide [Material] ROSETINUM (K18 gold + platinum), Diamond (total 0.04ct) *The rose platinum is only used for the motif part. The chain uses K18 pink gold that is made to resemble the rose platinum color. Product Description: After repeated trial and error, we finally arrived at SIENA's original material, "Rose Platinum". "Rose Platinum - Rose Platinum Gold -" created by the fusion of gold (K18) and platinum, features a deep, calm color that combines the elegance of gold and the dignity of platinum. It has an elegant and gentle color reminiscent of rosé champagne. Rose platinum, which requires a lot of effort and the skilled techniques of craftsmen, not only has a beautiful color, but also has less discoloration and is stronger than gold and platinum. ---------------------- Diamonds, the most scratch-resistant gemstone. Diamonds, which reveal their true beauty through polishing, bring out their original charm and give the power to open up the future and activate potential abilities. This is a simple and sophisticated long-selling necklace that draws flowing lines with such gemstones. The motif, which curves gently, creates a flowing line that does not make you feel the boundary with the chain, and creates a beautiful and delicate décolleté. Material: K18 (18k gold)
