{"product_id":"35mm-green-tourmaline-himalaya-mine-98326","title":"3.5mm Green Tourmaline - Himalaya Mine, San Diego County, California | Sold Per Stone | Pale Green","description":"\u003cp\u003eCalibrated 3.5mm round green tourmalines (sold per stone) from the Himalaya Mine, Mesa Grande District, San Diego County, California — one of the most historically significant gem tourmaline localities in the United States and in the global tourmaline record. The Himalaya Mine has been in continuous or near-continuous production since the late 1800s and supplied the Imperial Chinese court of Empress Dowager Cixi with tourmaline during the early twentieth century — a period during which San Diego County material was among the most commercially valuable tourmaline in the world. That historical pedigree, combined with the mine's active status as a producing locality, gives Himalaya-origin stones a provenance narrative that few American gem localities can match. For designers and buyers who value domestic sourcing and documented origin, California tourmaline carries genuine story value beyond its optical merits.\u003c\/p\u003e\n\u003cp\u003eThese stones present in a pale green, the cooler, more delicate end of the tourmaline green spectrum. Pale green tourmaline from the Himalaya Mine reflects the elbaite pegmatite chemistry of the Mesa Grande District, where color zoning, pastel tones, and clean crystal growth are characteristic of the deposit. \u003c\/p\u003e\n\u003cp\u003eTourmaline is not treated for color. These stones are natural, untreated elbaite from a named, documented American locality. Origin is verifiable to the Himalaya Mine, Mesa Grande District — a specificity of provenance that is increasingly valued by collectors, estate buyers, and designers building transparent, origin-forward inventory. Sold individually; slight variance in tone and weight is expected in natural faceted material from a single mine source.\u003c\/p\u003e\n\u003cp\u003eOrigin: Himalaya Mine, Mesa Grande District, San Diego County, California, USA\u003cbr\u003e\nSpecies: Tourmaline\u003cbr\u003e\nVariety: Green Elbaite\u003cbr\u003e\nCut: Round (faceted), calibrated\u003cbr\u003e\nSize: 3.5mm\u003cbr\u003e\nColor: Pale green\u003cbr\u003e\nSold: Per stone\u003cbr\u003e\nTreatment: None\u003cbr\u003e\nHardness: 7–7.5 Mohs\u003cbr\u003e\nRefractive Index: 1.624–1.644\u003c\/p\u003e\n\u003cp\u003eMaterials: California Tourmaline.\u003c\/p\u003e","brand":"Gem Enthusiast","offers":[{"title":"Default Title","offer_id":47553311408315,"sku":"3.5GreenTourmCA","price":49.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/8214\/1627\/files\/il_fullxfull.7856756899_1fuo.jpg?v=1774631499","url":"https:\/\/gementhusiast.shop\/products\/35mm-green-tourmaline-himalaya-mine-98326","provider":"Gem Enthusiast","version":"1.0","type":"link"}
