This item is a one-of-a-kind product and is available for immediate purchase. These are earrings featuring briolette-cut Swiss blue topaz, crystal, and round-cut lapis lazuli (4mm). The briolette-cut stones are all gem quality, approximately 6-8mm x 5mm x 5mm in size. The earring posts and catches are made of medical-grade stainless steel (316L). *316L is a stainless steel material with extremely low allergenic properties. It is also used in medical tools such as scalpels and scissors, as well as body piercings. For an additional fee, you can also change to omega clips (non-pierced earrings) or screw-back earrings. *Lapis lazuli is the birthstone for December (also the guardian stone for Libra and the Year of the Dog), and blue topaz is the birthstone for November (also the guardian stone for Sagittarius and the Year of the Rooster), so it is also recommended as a gift for those who are applicable.
