FAQ
How accurate is the chart for different countries? It lists exact conversions for U.S., UK, European, Japanese, and Chinese sizes, so you can trust the numbers for those systems.
Can I save my size for later? Yes. Use My Vault to store the size on your device without any cost.
Is this an official appraisal of my ring? No. The chart and widget provide sizing information only; they are not a licensed appraisal and do not buy or sell jewelry.
What if I need a custom widget for my jeweler site? Upgrade to Widget Pro for $12 / month per domain. It removes the attribution line and adds a custom call‑to‑action.
