I noticed there are people who would like to see more jewelry ID marks or siggies. I've got a nice collection, and right now I'll list a few. I've included some info about the companies, but I know there are others here with much more knowledge - Please add what you can!! I have bunches more; I'll break them up into several articles.
On my other blog,
Brain Damage in the Fast Lane, I will be posting Fabric Identification information. Burn testing directions AND pictures - lots of pictures - about what these look like - they can be confusing!! Other hints too.
Anyway, here are some jewelry marks:
This is a little enamel HAR flower I'm going to have trouble parting with...

I have several Mexican silver pieces; this one is from Taxco; you can tell because the number starts with T. The rest of the number refers to when it was made & who the artisan was.

Two Sisters is a contemporary company; it was founded by 2 of the 3 people who founded MYLU (whose names I completely forget) - I think they may still be in production.

SFJ - no longer in production, but no one seems to know anything about them. Items seem to be from 70-80s.

Grosse & Henkle: extremely well-respected Germany firm. Made a lot of jewelry for Christian Dior. This piece (which I have for sale) is identical to one they made for CD.

Metropolitan Museum of Art (NYC) Some are vintage, some aren't. This piece isn't - it's still sold.

Originals by Robert - almost always on a cartouche. He was a designer for Miriam Haskel before founding this firm. The company was renamed to simply "Robert Originals" but this was never used on the jewelry.

One of the ubiquitous Sarah Coventry marks - perhaps the most common.

This is the stamp of the "ruby Z" company founded by Candice Loheed, one of the premier founders of the California Ceramic Jewelry movement. Originally one of the founders of "Parrot Pearls), she left to form her own company - as did several others. This is a stamp, not a signature. This pin was hand made & hand painted but not by CL personally.

This is a pewter Modernist pin by Rune Tennedmed of Sweden. The mark is pre-1958 ; he used a copyright symbol starting in '58.


Here's a Sandor mark that came on this sweet enamel flower - a delightful surprise!


I think this is enough for now!! I'll keep posting more periodically.Most of these pieces are for sale in my Bonanzle store,
Dragonmum's Vintage Valuables.
Questions, comments & buyers welcome!!
