Second Earrings 18K K18YG Certified 12-month Birthstone 4mm Thick Shaft 12mm Delicate Simple Stud Earrings Continuous Wear Metal Allergy Resistant Women's Natural Stone Made in Japan 【Product Details】Tanzanite Second Earrings, Diameter: Approximately 4mm, Metal: K18YG, Shaft Length: Approximately 12mm, Shaft Thickness: 0.8mm~0.9mm. Silicone catch included. Made with peace of mind in Japan. Mass-produced overseas products often have sloppy construction at the post attachment, which can easily damage the piercing hole, but our products are smoothly finished by skilled craftsmen in Kofu. Tiffany claw, carefully set with 6 claws, creates an exquisite gap when viewed from the side, allowing for ample light to enter. 【Product Features】Compared to the usual thickness of 0.6mm, we use a 0.9mm thick shaft post for strength, making it less likely to bend and ideal for stabilizing the piercing hole. Also, a length of 12mm is recommended because the earlobe is slightly swollen after piercing. The length of the post is also necessary for caring for the piercing hole. Heavy earrings can also put a strain on the piercing hole. The 3mm diameter gemstone has a moderate presence and can be used for everyday wear or work. Because you wear them for a long time, we have focused on the material and used materials that are less likely to cause allergies. *Please note that not everyone will be free from allergic reactions. *Please note that there may be an error of about 0.1~0.3mm depending on the size measuring instrument. 【About Tanzanite】It is said that when you wear it when you have a big job, a new environment, or a dream or goal you want to achieve, but you can't quite feel positive, it will give you the ability to make correct decisions with a calm judgment and a sense of balance, and to take courageous actions to develop yourself and gain confidence. It is also said that even if trouble or difficulty comes, you may suddenly come up with a solution. *Remarks: The product is photographed in a color as close to the actual product as possible, but the color may differ slightly from the actual product due to the light source, camera, and monitor screen. I purchased it and kept it at home, but I'm giving it away because I stopped wearing earrings. Brand new, unused. ＊------------＊------------＊ Thank you for viewing. I am committed to a pleasant transaction. Thank you very much☆
