The star on this cabochon is well above the ordinary. Unheated material carries a premium in the trade, and the combination of an untreated stone with a strong star at nearly eleven carats places this piece in collector territory rather than fashion. The baguette work is a deliberate period-correct choice; the straight lines of the channel set stones frame the curve of the cabochon without competing with it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE ON VIEWING:\u003c\/strong\u003e A star is best observed under a single point light source such as direct sun or a spotlight. Under diffuse or overhead office lighting the rays will soften and may appear to vanish. This is a property of asterism, not a defect in the stone.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWeights and grades stated are approximate and determined while the stones are mounted, in accordance with standard practice for jewelry examined in the setting.\u003c\/em\u003e\u003c\/p\u003e","brand":"Pryce House","offers":[{"title":"Default Title","offer_id":45962946674748,"sku":"PH-4441173764","price":10680.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/7111\/0204\/files\/30A2B4F9-C6A9-4CDA-9C4B-9E396BEA6299.png?v=1787580503","url":"https:\/\/prycehouse.com\/products\/natural-unheated-blue-star-sapphire-10-83-ct-and-diamond-ring-in-18kt-yellow-gold","provider":"Pryce House","version":"1.0","type":"link"}
