Buying guide
Celtic knotwork uses lines that weave over and under each other in a closed loop with no start or finish. On this ring the knots form the shoulders on either side of the lab-grown ruby and are left open, so the pattern shows as fine metal lines with the skin visible through them. The lab-grown ruby sits alone above them, which keeps the design simple at the top and detailed at the sides. Many buyers choose it as a celtic lab-grown ruby engagement ring.
Ruby is red corundum and rates 9 on the Mohs scale, harder than any gem except diamond and moissanite, so it suits everyday wear. Lab-grown ruby has the same chemistry and hardness as natural ruby and an even, saturated red. Round and cushion shapes give the most sparkle; oval, pear and marquise look longer on the finger; the heart is a natural fit for a red stone.
Carat options run from 1 to 9 carats total weight. Yellow and rose gold deepen the red, while white gold, platinum and silver make it look brighter. 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.
