Both the heart-shaped and rounded square stones are fluorite. The heart-shaped one is transparent, and the stripes and gradations are very beautiful. The rounded square fluorite has cracks inside the stone, and the color is less transparent, but you can see rainbows in some places. [Design Bracelet] - Size: Inner diameter: Approximately 17cm - Materials: Fluorite (heart-shaped) 12mm Fluorite (rounded square) 10-11mm Alloy parts I make natural stone bracelets for myself as a hobby, but I have leftover materials, so I'm selling them at a low price. Please note that this is a handmade item, and as it is a natural stone, there may be some scratches, and there may be some slight measurement errors. #NaturalStone #Bracelet #Handmade
