This effect is called asterism. In this case, it creates a beautiful 6-rayed star.\u003c\/p\u003e\n\u003cp\u003eIts gorgeous blue color complements it perfectly! Untreated star sapphires are often more gray in color. This untreated blue sapphire, combined with its wonderfully defined star, is therefore a true rarity.\u003c\/p\u003e\n\u003cp\u003eThe star is most clearly visible in direct light, such as sunlight. There is also a photo showing the sapphire in which the star is not visible. For example, in the shade or in very diffuse light. But even then, the sapphire looks absolutely stunning. \u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe authenticity of all our sapphires has been verified by independent laboratories.\u003c\/em\u003e\u003c\/p\u003e","brand":"SapphiresByTim","offers":[{"title":"Default Title","offer_id":55326804509014,"sku":null,"price":552.0,"currency_code":"CHF","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/0546\/3126\/files\/IMG_20260906_122850_2.jpg?v=1789139617","url":"https:\/\/sapphiresbytim.com\/en-ch\/products\/1-91ct-blue-star-sapphire-from-sri-lanka-ceylon","provider":"SapphiresByTim","version":"1.0","type":"link"}
