Marcus Tempus

Product Story

Some rings make a statement through brilliance. Others are remembered for their remarkable colour.

Crafted in luxurious 18ct yellow gold, this elegant trilogy ring celebrates the timeless beauty of a natural oval-cut ruby, beautifully complemented by a pair of matching oval-cut diamonds. Thoughtfully proportioned and refined in every detail, it is a design that places exceptional coloured gemstones firmly at the heart of the piece.

At its centre sits a vibrant 0.65ct natural ruby, measuring 6.00 × 4.00mm. Chosen for its rich crimson colour and graceful oval silhouette, the ruby captures light beautifully while displaying the depth and character that have made this gemstone one of the world's most treasured.

Flanking the centre stone are two oval-cut diamonds, perfectly matched to mirror the shape of the ruby. Their elegant proportions create a seamless flow across the ring, allowing light to move effortlessly through the design while enhancing, rather than competing with, the remarkable beauty of the ruby.

The classic three-stone setting is finished with clean, polished shoulders that keep the attention where it belongs—on the gemstones themselves. Refined, balanced and effortlessly wearable, this is a ring that feels equally suited to everyday luxury, a meaningful anniversary, or a distinctive engagement ring for someone who appreciates exceptional coloured gemstones.

Beautiful today and timeless for generations, it is a piece created to become part of your story.


Why We Love This Design

The beauty of this trilogy ring lies in its harmony.

Using oval diamonds rather than the more traditional round brilliant cut creates a wonderfully balanced composition, echoing the shape of the centre ruby and giving the ring a softer, more elegant profile. The warm glow of 18ct yellow gold enriches the ruby's natural colour while providing a beautiful contrast to the bright white diamonds.

Why We Treasure Ruby

Ruby is one of the most celebrated gemstones, treasured for its vivid red colour, rarity and remarkable strength. As a member of the corundum family, ruby combines exceptional beauty with excellent durability.

Its rich colour has long been associated with passion, vitality and devotion, making ruby a meaningful choice for jewellery designed to be worn, loved and passed between generations.

Natural rough ruby crystal

Nature’s Artistry

Every ruby begins as a crystal, formed through extraordinary geological conditions deep within the Earth.

Caring for Ruby

Clean ruby jewellery with lukewarm water, mild soap and a soft brush. Avoid harsh chemicals and take care around delicate settings, particularly when wearing ruby rings.

Store ruby jewellery separately from softer gemstones to help prevent scratches. Natural inclusions are part of each ruby’s individual character.
