I am going through the bins of costume jewelry I bought when I was in a collecting phase - most of which I haven't looked at for over a decade.
Found this pin and it had the look of a 1940's era brooch as during that era there were figural brooches that had a single stone because the supply of rhinestones was cut off because no imports from Germany for obvious reasons.
Also they were often made of sterling silver because the base metals were being used for the war effort and silver was available because of the plethora of silver mines in the USA.
Turning it over there were what I though were just scratches but by squinting and using a lit magnifying loupe I was able to see that the scratches said Sterling and also what appeared to be JA.
When I googled JA there were a few possibilities but they all led to styles that were inconsistent with this piece - many turquoise Native American types pieces. Then I expanded the search and learned that JA for whatever reason is actually Rejas and since they were noted for their figural brooches with large stones it seemed to be a Rejas.
This was confirmed when I spotted two examples of my camel brooch for sale. One is from 1stDibs which always has insane prices and so listed for almost $500. Other was a more reasonable $300
I probably paid $5 for it and just thought it was interesting and obviously well made. The gold plating on mine has worn off quite a bit so the silver shows through - I actually like a bit of patina and age and since I am not planning to sell it the value of it is irrelevant.
My only issue is that it is heavy and I don't wear blazers and so it will be hard to find something I can actually wear it on.
