Has anyone any experience with hallmarks?

[Collectorofcookbooks]

Trying to decipher this one and I’m getting nowhere. Can anyone help?

Apparently is UK made, mid 30’s, platinum and white sapphire. Needs a good clean!

Looks like JHL then a crown, 18, can’t tell, a wonky 9...

Are you sure it is Platinum and not white gold? The JHL is normally the makers mark, a typical crown is for gold, 18 would normally mean 18kt gold and the funny 9 is probably a date letter (they look different each cycle so you can identify them).

Well, I was told VERY firmly it was platinum - doesn’t mean it is though!

I just want to make sure I clean it properly, that’s my main concern. It’s filthy.

Get a silver polishing cloth and give it a gentle going over. You can buy the infused cloth in the supermarket. If the stones are all solid gently clean it with a little soapy water and a soft toothbrush before rinsing it and buffing with the cloth. I always do this over a sieve just in case a stone comes loose.

It may have some platinum in the setting but it sounds like it is hallmarked as gold. Try and get a better close up picture of the hallmark though, I use the macro setting and move the camera back and forth gently until it focusses. A better view of the hallmark could help with identification.

Thanks, I’ll give that a go!

If it has a crown then it is gold. Platinum has an orb symbol. Plus 18 indicates 18 carat, a gold standard.
