Diamonds are often used as symbols of love and were even thought to form part of Cupid's bow which is why we use them in all our Platinum Round Diamond Trilogy Engagement Ring designs.

At Diamond Heaven we have a beautiful range of Engagement Rings available: from the stunning single diamond of the Solitaire Engagement Ring, to the ultimate symbol of love, the Trilogy Engagement Ring.

All our Engagement Rings are designed with passion and are handcrafted by our experts, with the 4Cs (Cut, Clarity, Colour & Carat) in mind, to ensure that every ring is truly unique: just as every relationship is.
