Handmade earrings. Made with aquamarine and blue Swarovski beads (5mm, 4mm). The transparent shine is very beautiful. ☆☆What is Swarovski?☆☆ Swarovski beads are manufactured by the Swarovski company in Austria. The crystal has a high lead oxide content of 32% or more, which increases transparency and light refraction, enhancing the shine. In addition, the surface is machine-cut using advanced technology, resulting in a beautiful shine, and they are considered to be the highest quality beads. Metal posts are used. We apologize, but please refrain from purchasing if you have a metal allergy. (We also sell the same design with titanium posts) These are handmade items by an amateur, so there may be some imperfections. We appreciate your understanding before purchasing.
