Artisan Crafted 18k & sterling cuff and necklace with pendant

Artisan crafted 18k & sterling silver gemstone cable hinged cuff and necklace with gemstone pendant. Both pieces are marked 18k, 925 and Indonesia. I think the pink gemstone is pink opal or pink quartzite. Not sure, there is 18k going around the gemstone plus small beads going around gemstone. The cuff is about 6 1/2 inches. It is very easy to get on and off. The chain is 17 1/2 inches and the pendant is 1 3/8 inches by 3/4 inches. This is a really nice set
