Contemporary Asscher cut Diamond Solitaire Engagement Ring

The Sonnet Engagement Ring perfectly defines the Asscher cut's outline and geometric beauty. This square Emerald cut style possesses subtle stepped facets combined with polished corners. The design is distinctively simple, with four sculptured claws in a choice of precious metal options. Choose from Fairtrade or regular 18ct Gold in white, yellow and rose coloured variations. Select your Diamond carat weight, colour and clarity from a wide range of quality options. This elegant setting allows light to pass freely and uninterrupted through the side of the stone, revealing the crystal clarity of your Diamond. Falling away on either side, with knife-edged shoulders flow towards the comfortable 2.5mm court-shaped band, perfect for everyday wear. The Sonnet Engagement Ring design benefits from a practical setting height of approximately 5.5mm from the finger. Your ring can be ready for dispatch in around four weeks of placing your order. We will create and deliver your order, made to your exact specifications, beautifully presented with the addition of a reputable Diamond grading certificate and insurance valuation. We will include the presentation box and pocket box within your box—perfect for a surprise proposal.
