Buying guide
The shoulders of this aquamarine Celtic knot ring are worked into interlaced knots that loop without a clear beginning or end, a motif long tied to Irish and Scottish design. The knots stay open, so they read as fine metal tracery beside the gem. The aquamarine sits alone at the top as a solitaire, which keeps its pale blue color the center of attention.
Aquamarine is a blue variety of beryl and the birthstone for March. It rates 7.5 to 8 on the Mohs scale, so it handles daily wear well with ordinary care. Its light blue tone shows best in larger sizes, and carat options here run from 1 to 9 carats total weight. Emerald and Asscher-style step cuts show the color as a clear, watery glow; oval, pear and marquise shapes look long and graceful; round, cushion and princess shapes give more sparkle.
White gold, platinum and silver match the cool blue of the stone, while yellow and rose gold give a warm contrast. Gold is offered 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.
