Deep ultramarine marbled with grey-white calcite and pinpricks of gold pyrite, Lapis Lazuli Faceted Rectangular Beads are flat 10x8mm tablets with a light facet cut, some beads nearly solid royal blue and others broadly streaked with light mineral. Rows of them sit tile-like side by side, which gives multi-strand collars and wide cuff bracelets a dense band of blue. Size: Approximately 10x8mm; faceted rectangular tablet with a polished finish Material: Natural Lapis Lazuli, faceted rectangular shape Quantity: Sold per 15.5 inch strand, approximately 31 beads FAQWhat are these beads best for? 10x8mm faceted Lapis rectangles suit statement necklaces, wide multi-strand cuffs, chandelier earrings and beaded collars, and the deep blue pairs strongly with gold-plated and brass findings, pearls and carnelian.What gives each bead its markings? Lapis Lazuli is a natural stone, so the amount of grey-white calcite and gold pyrite changes on every 10x8mm tablet across a 15.5 inch strand. Colour and pattern shift bead to bead.Packaging: Every strand is carefully packed to arrive safely, ready to use right away.
