Any Swarovski collectors/experts?

I have a harlequin/jester brooch that I believe is an unsigned Swarovski piece. It's well made, gold tone metal, enamel pants and a Swarovski? crystal paved shirt. I can't locate any kind of signature or stamp on it but I have seen a handful of unsigned Swarovski jewelry items on the market. I was able to locate one other identical but different color enamel pants that had sold on Etsy as a 'rare' Swarovski brooch. This one also did not appear to have a signature or stamp. Is there a Swarovski history website I could consult or does anyone recognize this from a specific theme or line of Swarovski items?

 

Many jewelry makers use Swarovski stones in their jewelry. I know more about their figures, but I believe they also mark their jewelry.

I just checked out my collectors' book & they show all brooches marked with a swan.

 

I wonder if it is Boucher?

 

Boucher jewellery is marked. It could be based on a Boucher design though.

 

I know these are identified on the internet as a "jester" or "harlequin" but... Looks more like a costumed ballet dancer in an arabesque position to me.

Ohh it does look like Boucher. Especially if you look at the hands feet and heads of other dancer figural brooches. The overall style looks very similar. But how to verify with no stamp

 

It looks like a take on Petrushka as choreographed by Fokine for the Ballets Russes:

 

Bocher's work is much more finely done and expressive.

As noted, Boucher was signed and most often stamped with a design number. Swarovski jewelry, made entirely by them, is clearly marked. The OPs pin looks like a nice piece of rhinestone jewelry, but it's impossible to know whodunnit.
