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. Preview proportions vary with cut and fit.
- 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.
