Trust Badge



This charming antique Sapphire and Diamond trilogy ring is simply stunning and would make an exceptional engagement ring! It's classic, regal and easy to wear.

The ring is crafted from 18ct Yellow Gold with a chunky 0.55ct old cut Diamond centre stone and two striking royal blue Sapphires. The rich Yellow Gold compliments the Sapphires perfectly and the smooth Gold band is somehow robust yet elegant at the same time. 

The Diamond is truly a thing of beauty; with superb fire and brilliance and bright white colour. 

We adore the grooved shoulders and over-sized antique hallmarks, and what's more the ring is perfectly straight so it looks great worn next to other bands such as a wedding ring or eternity ring!

VERY GOOD / EXCELLENT:  A beautiful antique Sapphire and Diamond trilogy ring in excellent condition. The gems and setting are both flawless and the large antique hallmarks are still perfectly crisp. The chunky old cut Diamond centre is stunningly bright and lively, and the Sapphires are evenly matched and a beautiful deep royal blue. There is no thinning to the back of the band, as is the case with so many antique engagement rings, and it's still strong and sturdy enough for daily wear.

The only tiny imperfection we could find is that the Diamond is one claw deficient but is held in place by at least 6 other claws all around. All the gems have been thoroughly checked and are secure with no movement whatsoever so it's perfectly safe to wear it as it is for some time.
