A blue diamond ring solitaire puts one fancy blue center on its own, with the center chosen in the next step. Settings come in ten shapes, from round and oval to Asscher and radiant, with plain, pave, twisted, cathedral, bezel and hidden halo styles. Every setting comes in white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver.

A solitaire keeps all the attention on one stone, which works well for color. With no halo around it, the blue reads clearly against the metal. A plain band is the purest version of a blue diamond solitaire engagement ring. Many designs add pave lab-grown diamond accents along the band for sparkle without competing with the center, and hidden halo designs tuck a ring of small accents under the center where it shows from the side.
Prong settings let the most light into the center and show its full outline. A bezel wraps the edge in metal, which protects it and gives a modern, sleek look. Cathedral settings raise the center on arches of metal, twisted bands add movement, and vintage designs bring milgrain, engraving or floral details. Split shank and bypass bands spread the shoulders for a wider look on the hand.
White gold and platinum make blue look cooler and deeper, while yellow and rose gold add warmth and contrast. Gold comes in 10K, 14K or 18K. Settings start under $150, and most fall between about $600 and $1,100. That price is for the setting only; the blue center is priced when you choose it.
