In short
Hammered black, dome: price, weight and delivery
| Width | How it reads | Weight, est. | Price |
|---|---|---|---|
| 6mm | Classic, the usual starting point for a band | 3.2g | £269 |
| 7mm | Classic to broad, more of the pattern shows | 3.7g | £269 |
| 8mm | Broad, a ring that is clearly there | 4.2g | £294 |
| 9mm | Wide and bold, best on a larger hand | 4.8g | £294 |
| 10mm | Wide and bold, best on a larger hand | 5.3g | £294 |
Weights are estimates for a plain band of the same width in black zirconium at UK size N with a 1.6mm wall, from our ring weight calculator. A pattern cut into the surface removes a little metal, so the finished ring is slightly lighter. Not sure of the width? The band width guide helps you choose.
- When it arrives
- 1 to 2 weeks to make, then one working day in the post.
- Delivery and returns
- Free UK delivery, insured for its full value, tracked and signed for. 30 days from delivery, return postage paid, unless you have it engraved. How returns work
- Size

- Resizing
- Not in the usual way. The black is grown into the surface of the metal, so cutting or machining the band would show bright metal underneath. That is why the size is settled before the ring is made and every ring is made to that measurement.
- Titanium or black zirconium
- Titanium is the lighter of the two at 4.5 g/cm³ against 6.5. Black zirconium has the harder surface, around Mohs 8 against 6. Neither is plated and neither tarnishes. Black zirconium or titanium, compared

About this ring
Hammered black, dome, in detail
A dome profile black zirconium band with a hammered surface across the whole outside. There are no bright edges and no inlay: the ring is black from edge to edge and the hammering follows the curve of the dome.
How it wears
A hammered surface shows everyday marks less than a smooth one. The dome profile has rounded shoulders, so it slides on and off easily. Black zirconium's surface is around Mohs 8 and the metal is hypoallergenic, at 6.5 grams per cubic centimetre.
Choosing yours
At 6 or 7mm the dome is gentle and the texture reads as a fine shimmer; at 9 or 10mm it covers more of the hand. It is paired with Hammered black, bright edges, the same hammered dome with bright metal at both edges.
How it compares with the rings nearest it
| Ring | What sets it apart | Metal | Widths | Surface hardness | From |
|---|---|---|---|---|---|
| Hammered black, dome (this ring) | A domed black zirconium band, hammered all over. | Black zirconium | 6 to 10mm | Mohs 8 | £269 |
| Hammered black | Struck by hand, so the facets never land twice the same way. | Black zirconium | 4 to 10mm | Mohs 8 | £255 |
| Roman numeral | Your date, cut around the whole band in numerals. | Black zirconium | 4 to 10mm | Mohs 8 | £329 |
| Scattered set | Diamonds flush set at irregular intervals, not in a line. | Black zirconium | 4 to 10mm | Mohs 8 | £349 |
There are 28 black zirconium bands in the range, from £199 to £1,525. All about black zirconium.
The metal, in brief
Heating zirconium forms a black ceramic oxide at its surface. The colour comes from that oxide, rather than applied black plating. It is a hard surface over a softer metal core, so scratch resistance does not mean the whole ring is black or immune to damage.
Surface hardness Mohs 8, density 6.5 g/cm³. It is hypoallergenic, so it is a sound choice for skin that reacts to nickel. It is not a precious metal, so it carries no hallmark.

About Hammered black, dome
- How much does the Hammered black, dome ring cost?
- £269 from 6mm to 7mm and £294 from 8mm to 10mm. That is the whole price: UK delivery is free, insured and signed for and engraving inside the band is included. The size makes no difference to the price.
- Can this ring be resized?
- Not in the usual way. The black is grown into the surface of the metal, so cutting or machining the band would show bright metal underneath. That is why the size is settled before the ring is made and every ring is made to that measurement.
- Is engraving included?
- Yes. It is optional. Leave the box blank and the ring is made plain. If you do want one it is laser cut inside the band where the ring is made, rather than sent out to a third party. There is no charge and no extra wait.
- How long will it take?
- 1 to 2 weeks. It is made in your size after you order, not picked off a shelf. That is the reason the widths and finishes are open choices.
- Can I return it if I have it engraved?
- Not for a change of mind. An engraving makes the ring clearly personalised, which puts it outside the statutory right to cancel. It cannot be resold. Every ring shop draws the line here. Order it plain and you keep the full 30 days. Either way, a ring that arrives faulty or is not what you ordered is covered by the Consumer Rights Act, which nothing waives.
- How much does the Hammered black, dome ring weigh?
- About 3.2g at 6mm, 5.3g at 10mm, estimated for a plain band in black zirconium at UK size N. Larger sizes and wider bands weigh more. It is a light ring by any standard: 18ct gold of the same size is more than twice the weight.
- What widths does it come in and do they cost the same?
- 6 to 10mm. 6mm, 7mm are £269 and 8mm, 9mm, 10mm £294, because the wider bands take more metal to make.
- What is closest to the Hammered black, dome in the range?
- Hammered black (black zirconium) and Roman numeral (black zirconium). The comparison table on this page sets them side by side on metal, width, hardness and price.
- Can I see the Hammered black, dome on my hand before I buy it?
- Yes. Our free ring try-on draws this ring onto a photo of your own hand, at any width from 6mm to 10mm, from this ring's own photograph. Press See it on your hand under the photograph. Each email address gets three pictures every thirty days and your photo is deleted once the picture is made.
- What if I get the size wrong?
- If it is unengraved, return it inside 30 days and we refund it and pay the postage. Use the free ring size finder first if you are unsure. If the ring is a surprise, ask us and we will talk you through the ways to find out without asking them.
- What should I know about black zirconium before I buy?
- The oxide is around Mohs 8: scratch resistant, not scratch proof. A hard knock against stone or steel can mark it and show the lighter metal underneath. A pale line is often metal rubbed off something else, which cleans away. Our maker refinishes black zirconium depending on the damage. Around machinery and electrics, follow your workplace rules on jewellery, whatever the ring is made of.
