This treatment is permanent, but often surface-concentrated. Therefore, significant polishing or excessive wear may alter the resulting color.\u003c\/p\u003e","brand":"Mathieu Blanchard","offers":[{"title":"Titans","offer_id":50524659548408,"sku":"PQUM14285S","price":29.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0471\/7199\/3767\/files\/quartz-naturel-rutile-taille-brillant-rond-6-mm-mathieu-blanchard-pqum14285s-quartz-naturel-rutile-taille-brillant-rond-6-mm-mathieu-blanchard-joaillerie-1176000689.png?v=1751309482","url":"https:\/\/mathieublanchardjewelry.com\/en\/products\/natural-quartz-rutilated-round-brilliant-cut-6-mm","provider":"Mathieu Blanchard Joaillerie","version":"1.0","type":"link"}
