Princess Trilogy Engagement Ring with Princess Side Stones in 18k Yellow Gold

Full description

This princess diamond trilogy ring in 18k yellow gold showcases a princess-cut centre diamond beside two matching princess-cut side stones. Classic corner claws secure each diamond and protect all twelve pointed corners. As a result, the three square silhouettes create a bold and beautifully balanced trilogy.

The princess cut combines a crisp square outline with lively brilliant-style facets. Moreover, its four pointed corners create a modern silhouette with strong light return.

Choose Your Perfect Diamond

Choose a premium lab-grown diamond or natural diamond to suit your priorities. Then compare carat weight, colour and clarity before confirming the centre stone. For clear guidance, the GIA guide to the 4Cs explains the qualities that shape a diamond’s appearance. Consequently, each choice can reflect your style, budget and preferred balance of size and quality.

18k yellow gold adds a rich warmth and a timeless jewellery character. In addition, its golden tone creates an elegant contrast with the bright diamonds.

Why Choose This Princess Diamond Trilogy Ring in 18k Yellow Gold?

Individual open baskets define each stone from the profile. Flowing supports connect those baskets into one cohesive gallery. The polished shank provides a calm contrast to the broad three-stone brilliance.
