Corrections

JewelLoop is a reference for people in the trade, so accuracy comes first. Every article and tool names the professional sources its facts come from, and we check them again when standards or rules change.

Found a mistake?

Write to [email protected] with the page address, what is wrong and, if you can, a source that shows the correct information. We read every message.

How we correct

• We check the point against at least one named professional source, usually two.
• If we were wrong, we correct the page and add a short note at the end of it: what changed and on which date.
• Spelling and layout fixes are made without a note.
• Facts on each article carry a “facts last checked” date.

What we do not change

Headlines from other publications link to their own sites; please contact that publication about its articles. Directory entries list places and institutions only, and are never ranked or paid for.
