Buying guide
Celtic knots are woven lines that loop over and under each other with no visible end, a pattern found in Irish and Scottish art. On this ring the knots shape the shoulders that lead up to the lab-grown sapphire. They stay open, so they read as a light tracery of metal and keep the eye on the center stone. The plain solitaire top makes this celtic lab-grown sapphire ring easy to pair with a simple wedding band.
Lab-grown sapphire is corundum, rated 9 on the Mohs scale, so it handles daily wear well. Lab-grown sapphire has the same chemistry and hardness as natural sapphire. Blue is the classic choice and pairs with any metal. Lab-grown pink sapphire looks soft and warm, especially in rose gold. Lab-grown yellow sapphire gives a bright, sunny tone that works well against white gold or platinum.
Oval, pear and marquise shapes lengthen the finger; round, cushion and princess shapes give more sparkle; the emerald cut shows the color in broad, calm flashes. Carat options run from 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K, and the band is about 2 to 2.5 mm wide. Prices start under $450 at the smallest option, and most choices sit near $1,200.
Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
