At ClassicJade, all product measurements are taken using a digital caliper and stated in millimetres (mm) unless otherwise indicated.
We value honesty and transparency and strive to provide measurements as accurately as possible. Where a piece is accompanied by a gemological certificate, the relevant jadeite measurements stated on our website are based on those recorded on the certificate.
Understanding Our Product Measurements
| Abbreviation | Meaning |
|---|---|
| L | Length |
| W | Width |

How to Read Our Measurements
For example:
Dimensions (Jadeite): Approx. 13.00mm (L) × 6.08mm (W) × 3.09mm (T)
This means that the jadeite measures approximately 13.00mm in length, 6.08mm in width and 3.09mm in thickness.
When a product is labelled “Dimensions (Jadeite)”, the measurements refer specifically to the jadeite itself unless otherwise stated.
Ring Size Guide
Our ring sizes are stated in Hong Kong / Singapore (HK/SG) sizing unless otherwise indicated.
If you already own a ring that fits comfortably, measure the inner diameter straight across the inside of the ring, from one inner edge to the other, at its widest point.
You can then refer to the approximate HK/SG ring size below.
| HK/SG Size | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 |
| Inner DIA | ~14.1mm | ~14.3mm | ~14.7mm | ~14.9mm | ~15.3mm | ~15.7mm | ~16.1mm | ~16.5mm | ~16.7mm | ~17.1mm | ~17.3mm | ~17.7mm |
| HK/SG Size | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 |
| Inner DIA | ~18.2mm | ~18.5mm | ~18.8mm | ~19.1mm | ~19.4mm | ~19.8mm | ~20.2mm | ~20.6mm | ~21.0mm | ~21.2mm | ~21.6mm |
This is an approximate conversion based on inner diameter. Ring sizing may vary slightly depending on the ring design and fit.
Jadeite Bangle Measurements
For jadeite bangles, In DIA (Inner Diameter) refers to the internal diameter of the bangle.
CS DIA (Cross-Section Diameter) refers to the thickness of the jadeite forming the body of the bangle.
If you already own a bangle that fits comfortably, you can measure straight across its inner opening from one inner edge to the opposite inner edge to compare its size with our product measurements.
