Sometimes you just can't go wrong with a classic! This timeless design of a three stone diamond ring is known as a trilogy ring, with each diamond said to represent the past, present and future. They have been popular for decades as a style of engagement ring which is no surprise with their romantic symbolism! 


The ring is made of 18ct yellow gold and is marked '18ct' inside the shank. The three old cut diamonds are set in bezel settings which have a light wash of white gold to the tops to compliment the stones.


The ring weighs approx 1.65g and the face of the ring measures approx 10.8mm by 3.7mm, the shank is tapers down to approx 1.6mm wide at the back. The diamonds are difficult to measures exactly within their settings but the centre diamond measures approx 3mm by 3.3mm and the two outer diamonds measures approx 2.8mm by 2.2mm.


Without a date hallmark, it's hard to date the ring exactly but give then style, materials and gold mark we believe it's likely Edwardian, early 20th century in age, circa 1910. 


Ring size - approx just under a US 6 (approx 5.75) / approx a UK L 


Condition - The ring is in wearable antique condition but does show some significant signs of wear and age. One of the outer diamonds has a chip to it and sits much lower within the setting than the other two diamonds. This is visible on close inspection and when under magnification. From a distance, because of the stones' sparkle it isn't too noticable. We think looking at the sides of the settings, either this diamond or all three diamonds may have been reset or the settings altered at some point in time. There looks to be a very faint resize mark to the shank and the gold does have some surface wear to it throughout. The 18ct gold mark is visible but is a little faint due to rubbing and wear. The last two photos have been taken with a loupe to show a magnified view of the stones and their settings. Please see photos.


*Please note the antique box and wedding ring pictured are not included in the sale but the ring will be shipped in a new presentation ring box and pouch*
