California tourmaline, particularly from San Diego County mines, has a loyal following among collectors and designers for its distinct pastel palette and provenance story, which can add meaning to a finished piece. Tourmaline has no cleavage, which makes it a relatively forgiving stone to set, though its terminations can be brittle so care with prong pressure is still warranted.\u003c\/p\u003e","brand":"Gem Enthusiast","offers":[{"title":"Default Title","offer_id":47943838138555,"sku":"CT105","price":49.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/8214\/1627\/files\/il_fullxfull.8121043066_r055.jpg?v=1781114920","url":"https:\/\/gementhusiast.shop\/products\/3mm-tourmaline-faceted-round-31x31mm-25883","provider":"Gem Enthusiast","version":"1.0","type":"link"}
