Allison Kaufman unveils 14K gold diamond semi-mount ring

The center stone is sold separately on Allison Kaufman’s 14K gold diamond semi-mount ring, a bridal piece Centurion listed at a $6,501 MSRP from Van Nuys, California. That single detail captures the way modular ring buying now works: shoppers can control the budget on the stone while still stepping into a high-gold, diamond-forward mounting.

Centurion published the ring on June 14, 2026 in its new product gallery as “NEW PRODUCT GALLERY: Allison Kaufman Gold Diamond Ring.” The listing described the piece as a 14K gold diamond semi-mount with a .50 total weight and made clear that the center stone was sold separately. In bridal jewelry, that format matters because the mounting and the center diamond can be chosen independently, letting the buyer decide how much of the final spend goes to gold work, accent stones and the main stone.

Allison Kaufman’s name carries weight in that equation. The Allison-Kaufman Company says it has been in business since 1920 and describes itself as one of the oldest and most respected diamond jewelry manufacturers in the United States. The company also says its jewelry is hand-crafted and inspected before receiving the AK trademark, a distinction that helps explain why its mountings show up across retail cases in both yellow and white gold.

Comparable Allison Kaufman listings point to a wide price spread inside the semi-mount category. Retailers are selling similar pieces at $1,376, $1,416, $3,300, $4,152, $5,001, $5,913 and $6,501, a range that reflects differences in metal, diamond total weight and design rather than a single fixed market for the brand. Whitestone Fine Jewelry, for example, described one Allison Kaufman diamond semi-mount as being designed in luminous 14K yellow gold, while another listing from the same retailer priced a 14K white gold split-band diamond accented semi-mount at $3,300 with .33 carat total diamond weight.

Other retailer listings underline how standard the semi-mount format has become for Allison Kaufman. One described 16 round diamonds totaling 0.50 carat weight. Another listed a 14K white gold semi-mount with a 0.09-carat center stone and “Ships Today” availability. Taken together, the listings show a bridal category built around flexibility, where the gold setting is as much the selling point as the diamond that eventually fills it.
