Material: Platinum Color: Blue Decoration: Other Stamped Pt900 on the back. Diameter: Approximately 5mm The actual color is slightly more green than in the photos, a very beautiful color like the sea of the South Pacific. I purchased it as apatite, but it feels like it could be called Paraiba tourmaline. When light hits it, the neon blue sparkles and shines, and it has a presence despite its small size ☆ I bought it new and have kept it in a jewelry box without using it. I will give it to someone who will use it ^_^ Sorry, no price reduction m(_ _)m
