Shop 4mm faceted loose Cubic Zirconias and loose crystal rhinestones for all 12 months, to make DIY custom birthstone jewelry, mother's jewelry and grandparent's jewelry. The crystal rhinestones are perfect for repairing antique rhinestone jewelry, as well as creating new resin jewelry, or anything that can use a sparkling pop of birthstone color.
Available in a wide variety of beautiful colors, cubic zirconias are synthetic (manmade) gemstones. Like diamonds and natural zircons, cubic zirconias have a very high refractive index, for maximum sparkle! Sometimes called cubic zirconium, these sparkling semiprecious synthetic gemstones are extremely durable. These loose 4mm cubic zirconias (CZs) work perfectly with our open-back sterling & GF tube settings and stone setting burnisher set, or can be snapped into our earring prong settings in seconds. See #Easy CZ stone setting projects in our Design Gallery for tips. Our expanded selection of silver solder makes it easy to solder the tube bezels onto your choice of sterling blanks or sheet, to create custom pendants, earrings and more.
Stones are listed below in birthstone order starting with January (Garnet) and ending with December (Blue Zircon).
