Buying guide
In a channel setting, the small stones sit in a row between two walls of metal, with no prongs between them. The surface stays smooth, so the band is less likely to catch on clothing, and the walls protect the stones' edges. Some designs fill the channel with tapered baguette lab-grown diamonds, some pair a channel with pave, and a bypass split shank design sets channel accents along its crossing rows. Others keep a solitaire look with channel set accents only on the shoulders.
Tanzanite is a blue to violet stone found in only one region of Tanzania, and it is one of the December birthstones. It rates about 6 to 7 on the Mohs scale, softer than sapphire, so take the ring off for the gym, gardening and cleaning, and avoid sudden heat. Every design offers 1 to 9 carats total weight. Cushion and oval shapes show the stone's color shifts well, while round and princess shapes look crisp next to the straight lines of a channel band.
White gold, platinum and silver keep the blue cool and bright, while yellow and rose gold add warmth. Gold comes in 10K, 14K or 18K. Prices start under $400, and most rings are between about $900 and $1,300.
