About men’s diamond rings
This page lists gold rings for men set with diamonds, including signet, dress and band styles, most of them in 9ct gold. Some are set with natural diamonds and some with lab-grown diamonds: each listing names the stone, and the carat of the gold.

Choosing a men’s diamond ring
Start with the setting. Many rings here are rubover set, where a rim of gold surrounds each diamond, which keeps the top smooth for a ring worn every day. Others use claws that lift the stone and show more of it, and a few are cluster or five-stone designs that spread several stones across the top.
Next, look at the gold. Most rings are 9ct gold, which is 37.5% gold, and a few are 10ct (about 41.7%) or 14ct (58.5%). Yellow gold is the usual colour, with a few in white gold or yellow and white together.
Some rings pair the diamonds with emerald, black sapphire or black onyx, and a couple use cubic zirconia. Lab-grown listings also give a colour and clarity grade, such as EF VS.
Signet tops vary a lot, so compare the top measurements in millimetres. Check your size with our Size Guide before you order. For plainer styles see men’s gold rings, or browse men’s signet rings.
Frequently Asked Questions
How do I find my ring size?
Rings that come in sizes have a Ring Size Guide beside the size selector on the product page, with NZ/AU letter sizes, the matching US sizes and the inside measurement. If you're unsure, visit our Ōtāhuhu showroom to be sized.
How do I know what stone is in a piece?
