This ring features a 0.70ct natural tanzanite sparkling with natural diamonds. The deep blue color is lovely, and the appearance changes depending on the angle of light. The material is K18 white gold (18 karat), and the weight is approximately 2.75g. The ring size is size 12. As it's the December birthstone, it has a special feel☺️ It's hardly been used, so the condition is quite good. The photos were taken with an iPhone 16 Pro, but the real thing is even more sparkly and beautiful✨ A ring box is included as a bonus! ※Feel free to ask any questions or negotiate the price〜♪ #Tanzanite #NaturalStoneRing #DecemberBirthstone #LadiesRing #K18WhiteGold #DiamondRing #JewelryLover #TreatYourselfJewelry #BlueStone #AccessoryLover Color: Navy系 (Navy-based) Material: Platinum Ring Size: Size 12 Scratches/Discoloration: None
