Art Deco Style Trilogy Diamond Engagement Ring

The Art Deco Engagement Ring is clearly defined by inspiration taken from the Art Deco Period of jewellery design. A slim feminine 1.8mm band meets 2 x 1.5mm Baguette cut Diamonds weighing 0.12cts together. The centerpiece of this exquisite vintage ring design stands approximately 5.5mm from the finger – a beautiful Princess cut Diamond is held within a defining part-bezel setting. Viewed from the side, the Deco Engagement Ring reveals the beauty of the exposed central Diamond at the heart of distinctive stepped fan shape - reminiscent of true Art-Deco styling. Crafted with consideration and expertise, Diamonds are selected from limited Worldwide supply and matched by trained eye by the Serendipity Diamonds team – completing this seductively simple ring design. Choose from a range of precious metal options and diamond sizes. Please note that the chosen Diamond weight from our main menu does not include the additional baguette cut Diamonds which increase the final diamond weight of the ring by 0.12cts. Please allow 3-4 weeks for your commission to be made before arriving luxuriously packaged and ready to present.

A Note on Diamond Cut Grade

One of the questions we are asked frequently relates to the cut grade of our diamonds. Australian clients are particularly interested in purchasing a beautifully cut diamond. For this reason, we set our minimum cut grade standard at "VERY GOOD" to ensure maximum brilliance, fire and scintillation. Where applicable this cut grade will be evident on accompanying certification alongside other details including carat weight, colour and clarity. For certification, we favour GIA amongst some of the World's most respected diamond grading laboratories.
