Next he was capable of creating synthetic ruby in a large enough size to use in jewelry.\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eSapphires took him about 8 more years to figure out but in 1909, Vernueil discovered that synthetic sapphires could be created with the addition of iron and titanium.\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eOver the next twenty years, the methods evolved and grew so popular, that synthetic stones found their way into even the finest of jewelers in the 1920s. Synthetic rubies and sapphires were EVERYWHERE!\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eThe methods has evolved since then, and today the synthetic stones are produced with HPHT: High-pressure high-temperature. This process mimics how earth-mined gemstones are made, but in a fraction of the time. An engineer crafts a liquid compound comprised of gemstone material and carbon, then utilizes the two components of heat and pressure to make a crystal.\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eThe stones are referred to as “synthetic,” but lab-created gemstones are in fact totally real and genuine; just man-made instead of mined from the earth. Lab gemstones are chemically, physically and optically identical to their natural counterparts. They come from the same recipe as those found underground.\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eThis particular synthetic sapphire is just magical! It has the most beautiful luminous color.\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eThe stone is crystal clear and measures 12x10 mm. It’s set in a super cool art deco inspired mid century 18k solid gold setting.\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eDepending on the light she goes from light orange to neon orange to red. Magic!!!\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eThe ring is Swedish and dates to the 1952. She has full marks for 18k gold, year and maker. 5.5 grams!\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eCurrently a size 8.5 US and sizeable by your local jeweler.\u003c\/p\u003e\u003cp style=\"text-align:start;\" class=\"\"\u003eThe condition is excellent with normal age related wear. The band has a ding and is not totally symmetrical as you can see in the last two pics.\u003c\/p\u003e","brand":"Oldmine","offers":[{"title":"Default Title","offer_id":60235778097486,"sku":"SQ0951652","price":550.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/3775\/8798\/files\/2E116D8A-47C6-4A58-8E95-A3BC4D2213F6.webp?v=1785233240","url":"https:\/\/oldmineshop.com\/products\/incredible-orange-swedish-sapphire-ring-18k-gold-1952","provider":"Oldmine","version":"1.0","type":"link"}
