Materials & diamond guidance
- Solid gold & platinum
- 9ct solid gold contains 37.5% pure gold, 14ct contains 58.5% and 18ct contains 75%. The remaining alloy affects colour and strength. PT950 contains 95% platinum.
- Diamond weight
- Carat measures weight, not face-up size. Shape and cut affect how large a diamond looks. The weight option states whether it describes a centre stone, a pair, or the whole piece.
- Clarity
- Clarity describes internal and surface features under magnification. SI, VS and VVS range from slightly included to very slightly and very, very slightly included; the number distinguishes grades within each group. It is not a percentage of clarity.
- Grading reports
- A report documents a particular stone’s carat weight, colour, clarity and cut where graded. A laboratory report is separate from the jewellery’s metal purity. Individual reports are not promised for every small accent stone.

About this piece
A single lab-grown diamond sits above a polished band in an open petal setting. The original design features an Old European-cut round centre, giving the solitaire its distinctive character. Alternative centre shapes are available in the product selector.
- Diamond weight: choose a 0.50ct, 1.00ct, 2.00ct or 3.00ct centre diamond. This is the weight of the single centre stone; carat measures weight rather than diameter.
- Metal: choose 9ct, 14ct or 18ct solid gold in white, yellow or rose, or PT950 platinum.
- Clarity: SI1, VS2, VS1, VVS2 and VVS1 options are available.
- Shape and fit: select your preferred centre shape and ring size on the product page. Your selection determines the final configuration and price.
