Shown in centimetres and EU sizesMeasure at home in 2 minutes
You need a strip of paper (or a string or shoelace), a pen and a ruler.
With a ring that fits (most accurate)
- Lay a ring you wear on that finger on the ruler and measure the inside diameter, edge to edge, in millimetres.
- Find that diameter in the table below.
With a strip of paper
- Wrap the strip around the base of your finger: it must still slide over the knuckle.
- Mark where it overlaps, lay it flat and measure it in millimetres: that is the circumference. Find it in the table below.
Measure at the end of the day, when fingers are slightly larger.
No ruler? A bank card is 8.6 cm long: count how many fit along your strip.

| 75 | 15 | Z+4 | 23.8 mm | 74.8 mm |
| 77 | 16 | Z+6 | 24.6 mm | 77.3 mm |
Half sizes sit halfway between two rows (about 0.4 mm of diameter).
Good to know: measure at the end of the day, when fingers are slightly larger. Wide bands (8 mm and more) feel tighter: if you are between two sizes, take the larger one. Tungsten carbide cannot be resized, so it is worth measuring twice.

He fears little, and the dragon says it for him.
Nothing rattles him, and everyone around him knows it. An 8mm black tungsten carbide band with a blue carbon fiber inlay showing a Celtic dragon down the center. A single round cubic zirconia sits above it. The inside is blue to match. The dragon is a pattern of coils and knots. US 6 to 14.5.
Hard tungsten, detailed inlay.
Tungsten carbide is one of the hardest materials used in jewelry. It marks far less than a steel ring and does not bend. It is nearly twice as heavy as steel. The black is a plating.

Details & specs
This ring is made from tungsten carbide, a material known for its hardness and strong resistance to scratching. It does not rust, so daily wear, water and sweat are part of normal life for it. The 8mm width gives it a substantial feel and a clear presence on the finger without looking oversized.
The band has a smooth black finish, a plated surface, stated plainly. A carbon fiber inlay with a Celtic dragon design runs along the center in blue, set below a single round cubic zirconia. The polished interior is colored blue to match the inlay, so the design holds together inside and out.
How to wear it
The design works on its own as a statement ring. Wear it to add a point of interest to a plain tee and jeans, or as a personal touch with business casual clothes. A black or steel watch suits it, and blue denim or a navy jacket brings out the inlay. Keep other rings on the same hand simple.
Choosing your size
Offered in US sizes 6, 6.5, 7.5, 8, 8.5, 9.5, 10, 12.5, 13, 13.5 and 14.5. The 8mm band has a wide profile, so many men choose a half size larger than they wear in a narrower ring. If your exact size is not listed, take the next one up rather than down.

Questions
Can the Celtic dragon tungsten ring stay on in the shower?
Yes. Tungsten carbide does not rust and the cubic zirconia is set into the band. A soft, damp cloth afterward keeps the blue dragon inlay clean.
Is the Celtic dragon ring too loud for business casual?
No. The black base keeps it versatile, and the blue dragon and the stone show on a closer look. A black or steel watch suits it, and a navy jacket brings out the inlay.
Should I size up for an 8mm band?
Often, yes. Wide bands sit closer on the finger, so many men choose a half size above their usual narrow-ring size, for example 8.5 instead of 8.
What is a carbon fiber inlay?
Carbon fiber is a woven material made of fine carbon strands, light and strong. Here it carries the blue Celtic dragon design along the center of the black band.
What does a Celtic dragon stand for?
In Celtic art the dragon is linked to power and protection, drawn with the coils and knots of Celtic knotwork. On this ring it is a pattern that rewards a closer look.
What is the stone on top?
One round cubic zirconia (CZ), set into the band above the dragon inlay. It is the only sparkle on an otherwise black and blue ring.
Why are some sizes like 7 or 9 missing?
The ring is offered in US 6, 6.5, 7.5, 8, 8.5, 9.5, 10, 12.5, 13, 13.5 and 14.5. If your exact size is not listed, take the next one up, for example 9.5 if you wear a 9.
Is it only available in blue?
Yes. It comes in one color: black outside, with a blue inlay and a blue interior.
