Custom Made Sterling and Gemstone Ring Signed

Custom made one of a kind sterling swan ring. Very heavy. 30 mm east to west. 20 mm north to south. Rises 10mm off the finger. Can be sized. Very large pear shaped topaz. I don’t remember what the green and pink stones are. I purchased this ring many years ago from the artist. It is signed with a cursive “O”. Absolutely beautiful and unusual.
