Cushion Trilogy Engagement Ring with Cushion Side Stones in 18k White Gold

Full description

This cushion diamond trilogy ring in 18k white gold showcases a cushion-cut centre diamond beside two matching cushion-cut side stones. Classic claws secure all three diamonds and preserve their softly rounded square outlines. As a result, the matching silhouettes create generous and beautifully balanced trilogy sparkle.

The cushion cut blends softly rounded corners with a square or elongated outline. Moreover, its brilliant-style facets create lively sparkle with an inviting romantic character.

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 white gold offers a bright polished finish with a refined modern character. In addition, its cool tone keeps the setting and diamonds visually cohesive.

Why Choose This Cushion Diamond Trilogy Ring in 18k White Gold?

Matching side stones extend the centre’s romantic cushion shape across the finger. Meanwhile, their graduated size keeps the principal diamond visually dominant. Individual open baskets define each stone clearly from the profile. Flowing supports connect those settings into one cohesive gallery. A plain polished shank provides a calm finish beneath the broad three-stone brilliance.
