Buying guide
Celtic knotwork is a pattern of lines that weave over and under with no visible start or end, long linked to Irish and Scottish craft. On this ring the knots form open shoulders on each side of the amethyst, so the metal carries the detail and the gem stands alone as a solitaire. The open work lets light into the stone from the sides and keeps the ring from feeling heavy.
Amethyst is purple quartz and the birthstone for February. It rates 7 on the Mohs hardness scale, hard enough for a ring worn with some care. Carat options run from 1 to 9 carats total weight. Smaller sizes give a neat, everyday look, while 4 carats and up make the purple color the clear focus. Oval, pear and marquise shapes lengthen the finger; round, cushion and princess look compact, and heart and emerald cuts add character.
Yellow and rose gold warm up the purple, while white gold, platinum and silver give a cool, crisp contrast. Gold comes in 10K, 14K or 18K. Band widths run from 2 to 2.5 mm. Prices start under $450 at the smallest option, and most choices fall between about $1,200 and $1,400.
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.
