An oval centre diamond is generous on the hand, and here it sits between two oval side stones chosen to frame it rather than compete with it. A trilogy is one of the older ideas in jewellery and one of the most personal, and at this scale every proportion matters. We design it in CAD with you, source your diamonds to brief, and finish the piece by hand in Hatton Garden. As a commission, the side stones can be scaled up or down to balance your centre.

Centre stone	Oval, your choice, 0.50 to 3.00 ct, GIA or IGI certified
Side stones	Two oval diamonds, around 1.40 ct total, E-F / G-H, VS to VS2
Setting	Six claws
Metal	9ct, 14ct or 18ct white, yellow or rose gold, or 950 platinum
Band width	2.30 mm

Accent diamond figures are based on a 1.50 ct round centre and vary with your chosen stone. Designed in CAD and hand-finished in Hatton Garden, hallmarked at the London Assay Office.
