Buying guide
A Celtic knot is an interlaced pattern with no start or end, often read as a sign of lasting connection. On this ring the knots are worked into each shoulder as open metalwork, leading the eye to the solitaire. The open design keeps the band light and lets the moissanite sit as the clear focus.
Round shows the most sparkle, oval and pear look longer on the finger, and cushion and princess give a softer or sharper square. Emerald adds a clean step-cut look; marquise and heart are the boldest outlines. Total weight runs from 1 to 9 carats. Moissanite is 9.25 on the Mohs scale and very bright, so it handles daily wear well. Prices start under $450, and many choices are around $1,200.
The band comes in 2, 2.2 or 2.5 mm widths. A slimmer band makes the center look larger; a wider one feels sturdier and frames the knots more fully. White gold and platinum give a cool, bright setting, while yellow and rose gold bring out the warmth of the knotwork. Gold comes in 10K, 14K or 18K.
