First time poster but long time reader. I'd appreciate any assistance in identifying these two heavy sterling bracelets by the same artist. They have a lovely sculpted design. One is a slip on bangle & the other a cuff.
There's a circular makers mark with "925" & other letters written within it. There's also a stylized cursive signature on each piece. I can't make out any of the letters, except for maybe a "Jill"? I'm hoping someone here easily recognizes it as these pieces are very nice:


I'm happy to provide additional images of the mark on my other bracelet if these aren't clear enough.
Many thanks in advance!
