Trilogy Diamond Cluster Engagement Ring
The Addison trilogy diamond cluster engagement ring provides a unique alternative ring design compared to traditional three-stone engagement rings. Three equally sized diamonds, matching in colour and clarity, sparkle at the heart of this contemporary ring design. Choose from three different carat weight options including:
0.50 carats - set with 3 x 3.5mm round brilliant cut diamonds
0.75 carats - set with 3 x 4mm round brilliant cut diamonds
1.00 carats - set with 3 x 4.5mm round brilliant cut diamonds (see images above)
The engagement rings represents one of few designs benefitting from a wider band and benefits from a comfort fit 3.5mm wide ring narrowing as each shoulder stylishly sweeps to meet the setting.
We individually craft each ring design, available in a choice of Platinum or Gold options tailored to your exact specifications. We present your finished ring in luxury Serendipity Diamonds packaging within a presentation box, accompanied by a slimline pocket box for your proposal.

Also, we offer most of our engagement rings with Moissanite instead of a diamond. This provides an ethical and affordable alternative to a natural or lab-grown diamond (also available) available across most of our ring styles.
