About 3-prong tennis necklaces
The 3-prong setting holds each diamond with three prongs rather than four or a full bezel rim. Compared to a 4-prong or buttercup setting, the 3-prong shows more of each diamond's surface, allowing maximum light to enter from the sides and creating a brighter, more open look. Compared to a bezel setting, the 3-prong is more traditional and exposes more of the stone's brilliance. Diana M's guide to tennis necklace settings covers the differences in more detail.
How it wears
A platinum 3-prong tennis necklace at 36ct is a significant high-jewelry piece — the weight of the diamonds creates a natural drape across the neckline, and the 3-prong construction allows the individual diamonds to move and catch light as the wearer moves. The platinum setting provides the most secure and durable construction for a necklace at this carat weight, and its cool tone lets the diamonds carry the visual story without warm metal interference.
For pairing: simple diamond studs or a single diamond ring complement without competing. Avoid additional necklaces at the same length.

A 3-prong setting uses three prongs to hold each diamond, compared to 4-prong (which adds an extra prong for more security and a slightly different visual) or bezel (which encases each diamond in a continuous metal rim). The 3-prong is the most open of the three — it exposes the most diamond surface to light, creating maximum brilliance. For a comparison of all three setting styles, see our tennis necklace settings guide.
Platinum is the most durable precious metal, which matters significantly for a 36ct tennis necklace worn against the body. Platinum prongs hold their shape better than gold over time and are less likely to bend or wear thin, providing better long-term security for each diamond. Platinum also has a naturally cool, white tone that lets the diamonds' color carry the visual story without metal interference.
The necklace is 16.5 inches, which sits at the collarbone — a collar length that keeps the diamond row visible against most necklines.
