Men's Black Diamond Bracelets

Style: black diamond bead bracelet, tennis bracelet or prong-set gold bracelet

Three bracelets string black diamond beads, and together they sold 132 of the 153 pieces bought in the year. Two list steel and 14K gold as the metal, at 3 and 4 mm across. The third, 7 mm, lists stainless steel and rides a woven cord that its listing calls adjustable.

The three tennis rows set black stones one by one in prongs along 14K gold, each listed at 7 inches: a 3.9 mm row, a 4.5 mm upside-down row and the Black Elegance, three rows at 7.8 mm. Four more gold bracelets hold black stones in prongs, 14K on three and 10K on one, from 2.8 mm up to a two-row 11.7 mm. One 14K evil eye and one sterling silver skull and cross round out the page. For white or colored stones, see men's diamond bracelets.

The stones: are black diamonds real, natural or treated, and AAA

A black diamond is diamond all the way through. Dense graphite and other dark inclusions turn it black, or heat and irradiation darken a heavily included stone, so light stops at the surface and you see a metallic polish rather than fire.

All 12 bracelets here read Natural on the origin line, which tells you the stone was mined, not grown in a lab. The evil eye's title and the 3 mm bead bracelet's description say natural as well. Not one listing tells you whether its black is the stone's own color or came from a treatment, so put that question to the desk. AAA prints in the details of 9 of the 12. It is a trade grade for an even black and a clean polish, and no gem lab gives it.

Metal: 14K gold, 10K, steel or sterling silver black diamond bracelets

Seven of the 12 are 14K gold and one is 10K. Five of those eight have a menu of yellow, white and rose gold; the other three come only as pictured. The bead bracelets list steel, two of them with 14K gold, and the skull and cross is .925 sterling silver. The evil eye's listing describes black rhodium plating over white gold, and a plating wears thin with time. To match one at the neck, see men's black diamond chains.

Size: black diamond bracelet length and width for a man's wrist

Eleven of the 12 list a length, from 7 to 8.5 inches. Two let you choose on a menu: the 3 mm bead bracelet offers 7, 7.5 and 8 inches, and the skull and cross 7.5, 8 and 9. To size one, wrap a strip of paper around the wrist bone and mark where the ends meet. A close fit is that length plus about half an inch, a looser one about an inch more; our men's bracelet guide has the chart.

Widths run from 2.8 to 11.7 mm on the 11 that list one. Five are under 5 mm, four sit at 7 to 8 mm and two reach 11 mm or more. For a length no menu shows, ask the desk before you order.
