18ct Rose Gold Ruby and Diamond Trilogy Ring - 1.33ct Total Three Oval Rubies, Diamond Border, No Heat Treatment Indicated



Overview

A wide and elegant three-ruby ring in 18ct rose gold that leans into its warm palette beautifully. Three oval-cut rubies in a vivid purplish-red medium-dark tone are set in individual rose gold bezels side by side across the ring head, creating a rich bar of colour. A continuous border of 24 round brilliant-cut G-H colour, SI1-SI2 clarity diamonds in white gold micro-claw settings runs along the top and bottom edges, framing the rubies in a bright, sparkling contrast. The mix of rose gold bezels, white gold diamond settings, and the red of the rubies is a considered, contemporary combination.



One notable attribute: the Gemley Valuations certificate specifically states "no indication of heat treatment" for the rubies, which sets them apart from the vast majority of rubies on the market where heat treatment is standard and near-universal. While the valuer's disclaimer notes this is opinion only and definitive confirmation requires laboratory testing, the absence of treatment indicators is a meaningful positive for buyers who value untreated stones.
