Please read my profile before commenting or purchasing. Made in Japan, a piece from Jewelry Maki. Since it's an older piece, the setting is very well-made. Simple platinum diamond earrings. They fasten firmly, so they're suitable for second piercings. Platinum is said to be less likely to cause allergies than 18k gold, so it's good for stabilizing the piercing hole. The diamonds are colorless and transparent, so they have a beautiful fire. The post on these is about 0.8mm thick and durable. The standard post size is 0.5mm. These posts have a deep groove, and the catch clicks securely, making them unlikely to fall out, so they're good for wearing continuously. The Jewelry Maki mark and Pt850 hallmark are on the post and catch. The back of the earring has a 0.1ct marking. Made in Japan, so the craftsmanship is meticulous. I will clean them with an ultrasonic jewelry cleaner before sending them. #PlatinumEarrings #DiamondEarrings #StudEarrings #SecondPiercing
