Natural Stone Ruby Loose Gemstones 3mm Approximately 58 Pieces & Stainless Steel Earring DIY Set - Stainless Steel Earring DIY Crown 3mm Handmade Materials Silver 24 Pieces New - Quantity: 24 pieces - Size: Approximately 3mm Crown - Material: Stainless Steel Earring backs are not included. - Ruby Loose Gemstones 3mm Approximately 58 Pieces Round Multi-faceted Cut Due to being an overseas product, details such as the origin of the ruby and whether it has been heated or not are unknown. There are variations in color due to the natural stone. Thank you for viewing. I purchased these intending to make handmade earrings, but the earring material was too small for the 3mm ruby stones, so this set doesn't fit perfectly. The stones can be used for various handmade projects such as rings, and the earring posts can be used with stones smaller than 3mm and with different materials. Please read my self-introduction.
