{"product_id":"black-star-sapphire-oval-cabochon","title":"Black Star Sapphire Oval Cabochon","description":"\u003cp\u003eThe eye-catching six-ray star of this oval black star sapphire cabochon and its deep-black color make it an ideal choice for a centerpiece design such as a pendant. Partner these designs with complementary-color cabs to create matched sets with bracelets or earrings, or us it to create more complex, multi-stone necklace designs.  Star sapphire is named for its distinctive six-ray star, visible under a single overhead light source, and occurs in black, blue and red corundum (red varieties are known as \"star rubies\"). The star is the result of intersecting needle-like inclusions within the gemstone that follow the underlying crystal structure and reflect light in a different direction than does the surrounding mineral, creating the appearance of the star. In a black sapphire, the inclusions are hematite, a mineral composed primarily of ferrous oxide. This star effect is known as “asterism.” The value of a given gemstone is based on the symmetry, orientation, definition, color and clarity of the star.\u003c\/p\u003e","brand":"Amadesa","offers":[{"title":"6 x 4мм","offer_id":52675164799322,"sku":"71863","price":96.0,"currency_code":"EUR","in_stock":false},{"title":"7 x 5мм","offer_id":52675164832090,"sku":"71864","price":16.9,"currency_code":"EUR","in_stock":false},{"title":"8 x 6мм","offer_id":52675164864858,"sku":"71865","price":33.8,"currency_code":"EUR","in_stock":false},{"title":"10 x 8мм","offer_id":52675164897626,"sku":"90799","price":96.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/71864.jpg?v=1763144868","url":"https:\/\/www.amadesa.com\/ru-ru\/products\/black-star-sapphire-oval-cabochon","provider":"Amadesa","version":"1.0","type":"link"}
