Is the onyx in these necklaces natural or treated?
Check each product page for whether the onyx is natural or lab-created. In general, most black onyx on the market is dyed or heat-treated to reach an even, deep black. That is a standard, widely accepted practice and gives the stone its consistent glossy color.
Which onyx necklace styles are most popular?
Stainless steel onyx styles and sterling silver single stones lead the list. Near the top are a textured black onyx necklace, beaded strands with tiger's eye or golden tones, and an inlay rectangle design. Sterling silver circle, checkerboard-cut, and halo styles follow close behind.
What affects the price of onyx necklaces?
Metal, stone size, and design drive the price. Sterling silver and stainless steel differ in cost, and a larger onyx, added cubic zirconia accents, or a longer beaded strand also change it. Use the Price filter on this page to set a budget.
What length of onyx necklace should I choose?
An 16 to 18 inch length sits near the collarbone. Many sterling silver pendants-style pieces here come in 16 or 18 inches, while stainless steel strands run 22 to 34 inches for a bolder, layered look. Children's styles are 14 inches, a snug fit for smaller necks.
