Persian turquoise specifically refers to material mined in Iran — historically from the Nishapur mines in Khorasan Province, which have been a source of turquoise for thousands of years. At 390 grams and 75 × 80 × 45 mm, this piece offers sufficient mass for multiple cabochon cuts or can be kept whole as a display specimen. It has not been stabilised or treated in any way.\u003c\/p\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003ch4\u003eWhat is the difference between raw turquoise and stabilised turquoise?\u003c\/h4\u003e\n\u003cp\u003eRaw turquoise is untreated stone as it comes from the ground, with no resin or chemical hardening applied. Stabilised turquoise has been impregnated with resin to improve hardness and colour consistency for jewellery use.\u003c\/p\u003e\n\u003ch4\u003eWhere does Persian turquoise come from?\u003c\/h4\u003e\n\u003cp\u003ePersian turquoise is mined in Iran, primarily from the Nishapur region of Khorasan Province. These mines have been producing turquoise for over 2,000 years and are among the most historically significant turquoise sources in the world.\u003c\/p\u003e\n\u003ch4\u003eHow many cabochons can be cut from a 390-gram turquoise rough?\u003c\/h4\u003e\n\u003cp\u003eThe yield depends on the distribution of colour and matrix within the stone. A 390-gram piece of this size (75 × 80 × 45 mm) can typically yield several small-to-medium cabochons, though the exact number depends on the lapidary’s cutting approach and the internal structure of the rough.\u003c\/p\u003e","brand":"Folkmarketgems","offers":[{"title":"Default Title","offer_id":53242773143841,"sku":"TURQ-390","price":550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0845\/4665\/0401\/files\/persian-turquoise-raw.webp?v=1786453367","url":"https:\/\/www.folkmarketgems.com\/products\/raw-persian-turquoise-rough-390g-iran","provider":"Folkmarketgems","version":"1.0","type":"link"}
