I have never seen antique pocket watch faces transformed into a beautiful piece of jewelry. The face itself is lovely, with beautiful engraving and raised numerals. The center diamond is approximately 5 points but does have a chip. I didn’t notice when I bought this. The shamrock has lovely seed pearls, I think the settings for the gemstones are gold. Looks like the initials on the back are EDB (possibly the watch maker). This can be worn as a pin or a pendant. Absolutely stunning piece!!
