Inner diameter: 16cm These are cute, plump heart-shaped fluorite stones. Can be disassembled into parts. Shipped via Nekopos (Japanese postal service) *Please refrain from detailed questions as I am not an expert. *I may misremember or have incorrect information about the names of the stones. *These stones contain natural inclusions, stone patterns, and chips. If you are looking for perfection, I recommend purchasing them in person at a store where you can handle them. Thank you for your understanding.
