Diamond bands
Titanium and black zirconium engagement rings

| Metal | Rings | Price | Widths | Surface | 6mm band, est. |
|---|---|---|---|---|---|
| Titanium | 8 | £365 to £1,345 | 4 to 10mm | Mohs 6 | 2.2g |
| Black zirconium | 3 | £850 to £1,525 | 6 to 10mm | Mohs 8 | 3.2g |
Prices include UK delivery and engraving. Weights are estimates for a plain 6mm band at UK size N with a 1.6mm wall (how they are worked out); the solid gold bands carry the maker's own weight on each ring's page. Surface hardness is on the Mohs scale, where a higher number resists fine scratches better.
Each ring here is a band with its diamonds set into it rather than raised above it, in titanium or in black zirconium, and each ring's page says how many stones it carries. Most are graded SI clarity and G to H colour, and each ring's page gives its own stones. A few carry coloured diamonds, blue or yellow, and their pages state that those stones are treated.
Titanium is the lighter metal, at 4.5 grams per cubic centimetre, and black zirconium has the harder surface, around Mohs 8. Every ring is made in your size.
About titanium and black engagement rings
- Can a diamond band be an engagement ring?
- Yes. These rings carry their diamonds in the band itself, so they work as an engagement ring for anyone who would rather not wear a raised stone, and as a wedding ring after it.
- What grade are the diamonds?
- Most are SI clarity and G to H colour, and each ring's page states its own. Where a ring carries coloured diamonds, the page says the coloured stones are treated.
- Are the black rings black all the way through?
- No. Black zirconium is heated so its surface turns to a hard black oxide, around Mohs 8, over the paler metal beneath. A ring with bright edges is cut back to that natural metal at the shoulders.
