Buying guide
Celtic knots are woven lines that loop over and under each other with no clear start or end, a motif long linked to Irish and Scottish design and often read as a sign of lasting commitment. On this setting the knots shape the shoulders, so the detail lives in the metal and the center sits alone at the top. It suits anyone who wants a simple solitaire with a heritage pattern.
Black diamonds are opaque, so they show a glossy, almost metallic luster rather than the white sparkle of a colorless stone. That dark, solid color stands out against the open knots and gives the ring a strong, modern contrast. Diamond rates 10 on the Mohs scale, so a black center is hard enough for daily wear. Round, oval and cushion shapes show the luster smoothly, while emerald, Asscher, princess and radiant cuts give a sharper, graphic outline.
White gold and platinum give the sharpest contrast with black, yellow gold looks rich and warm, and rose gold softens the look. Gold comes in 10K, 14K or 18K, and band widths run from 2 to 2.5 mm. Prices are for the setting only and start under $300; many options are around $1,050. The black center is priced when you choose it.
