Handmade sterling silver jadeite ring

Handmade sterling silver jadeite ring. Unique statement piece - D shaped piece of slightly transparent jadeite with gold flecks in a nice setting with etched detailing. The thin band has a column like design near the top. Possibly Israeli made, or Greek. Best color is the first photo - it’s more of a yellow green than a blue green. Stamped 925 and hallmarked (but I don’t recognize this mark), face is a bit over 1 x a bit over 3/4 inches, 6.47g. SPL
