This is one of the most exquisite antique 18ct Gold Diamond signet rings we have laid our eyes on! Complete with three large and impressive Diamonds, with a total carat weight of 0.55, you will definitely want to show this piece off. 

The Diamonds are set in a vertical pattern, offering a completely unique take on the all time classic trilogy design. The central diamond alone is 0.35ct, and a highly sought after F/G colour, and sandwiching this are two equally resplendent Diamonds, weighing a total of 0.20ct! 

We love the finger coverage that this piece so effortlessly provides, making for an exquisite statement piece when worn alone. The ring shank is deliciously wide, perfectly matching the proportions of the front panel, making for a comfortable and uber luxurious piece of Victorian jewellery!

EXCELLENT. This antique 18ct Gold Diamond singet ring is in excellent condition overall. The Diamonds have a bright sparkly finish and are securely set into place. The ring shank does bare some sign of wear, with a previous resize, meaning some of the hallmarks have been lost. This Victorian Diamond ring is gorgeous overall and the resize only becomes visible when you look up close! This is a beautiful one of a kind piece to treasure.
