This oval trilogy ring with trillion sides in 18k rose gold showcases an oval-cut centre diamond flanked by two trillion-cut side diamonds.

The oval cut brings a graceful elongated outline and lively brilliant-style faceting. Moreover, its proportions can create a flattering lengthening effect across the finger.

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 rose gold introduces a soft blush tone and a romantic contemporary character. In addition, its warmth gives the bright diamonds a distinctive and flattering contrast.

Why Choose This Oval Cathedral Trilogy Ring with Trillion Sides in 18k Rose Gold?

The trillion-cut side diamonds are hand-selected to complement and remain in proportion to the centre stone. Meanwhile, their tapered points guide the eye smoothly into the polished shoulders. Curved trellis supports form an open gallery beneath all three diamonds. Therefore, light can reach the stones from the side as well as above. Cathedral shoulders rise towards the settings and complete the trilogy with clean, flowing lines.
