- 199 in stock
Description
The two-tool ring sizing kit for jewelers who need both bench measurement and finger measurement in one set — an aluminum mandrel marked US 1–15 and EU 41–76 for checking and forming rings, paired with 27 stainless steel finger gauges covering US 0–13 in half sizes for accurate customer sizing.
Key Selling Points
- Two-tool set: aluminum ring sizer mandrel and 27-piece stainless steel finger gauge set — covers both mandrel sizing and individual finger measurement in one kit
- Mandrel measures US sizes 1-15 and European sizes 41-76 — dual scale markings for working with international ring size standards
- 27-piece finger gauge set covers US sizes 0-13 with half sizes included — no quarter-size gaps, suitable for accurate customer finger measurement
- Stainless steel finger gauges resist corrosion and maintain accurate dimensions over time — more durable than plastic gauge sets
- Lightweight aluminum mandrel at 0.24kg total kit weight — easy to handle during ring forming and sizing work at the bench
About This Set
Accurate ring sizing requires two different tools for two different tasks. The mandrel is used at the bench — you slide a ring onto the tapered cone to read its current size, or use it as a forming surface when shaping a ring band. The finger gauge set is used to measure the customer's finger directly, giving you the target size before you start making or resizing the ring.
This kit includes both. The aluminum mandrel covers US sizes 1-15 with European size equivalents marked alongside, so you can work with customers or suppliers using either sizing system. The 27-piece stainless steel gauge set covers US sizes 0-13 with half sizes, giving you the resolution needed for accurate finger measurement without the gaps that quarter-size-only sets leave.
Best For / Not For
| Best For | Not For |
|---|---|
| Jewelers and goldsmiths measuring finger size and checking ring size during making and resizing | Quarter sizes not included — the gauge set covers half sizes only (US 0 to 13 in 0.5 increments) |
| Jewelry studios working with both US and European ring size standards | UK, Australian, or Asian ring size systems — this set covers US and European sizes only |
| Ring forming and shaping work using the mandrel as a forming surface | Heavy hammering directly on the aluminum mandrel — aluminum can dent under heavy impact; use a steel mandrel for heavy forming work |

Pro Tips
- Measure the finger at the end of the day when fingers are at their largest — finger size fluctuates with temperature and activity, and sizing at the largest point prevents a ring that fits in the morning but is too tight by evening.
- When using the mandrel to check a finished ring, slide the ring down until it stops moving freely — read the size at the point where the ring sits without forcing it.
- For wide band rings, size up by half a size from the measured finger size — wide bands fit tighter than narrow bands at the same nominal size.
- Keep the stainless steel gauges dry and wipe them clean after use to maintain accurate dimensions and prevent surface oxidation over time.
Frequently Asked Questions
Does this set include quarter sizes?
No. The 27-piece finger gauge set covers US sizes 0 to 13 in half-size increments. Quarter sizes are not included. If you need quarter-size resolution, a larger gauge set is required.
Does the mandrel show European sizes as well as US sizes?
Yes. The aluminum mandrel is marked with both US sizes (1-15) and European sizes (41-76) on the same scale, so you can read either system directly without conversion.
Can the mandrel be used for ring forming and shaping?
Yes, for light forming work. The aluminum mandrel can be used as a forming surface for shaping ring bands. For heavy hammering or aggressive forming, a steel mandrel is recommended as aluminum can dent under heavy impact.
