10K White Gold Pink & Purple Pendant on Sterling Silver Chain

10K White Gold Pink & Purple Pendant on a Sterling Silver Chain. I believe the stones are pink and purple but I have a hard time with colors so I could be wrong and they could possibly be different shades of pink. I believe the top part of the pendant setting which holds the attached dangling pendant is stamped 10K. See pictures as it is hard to read so I’m not positive that is what it says. I’m unsure what the pink and purple stones are. The chain I put this on is Sterling and is marked 925. I never had this appraised so I can not give you more information but I can say that it is a very pretty necklace and it would be great with a formal gown. It has been worn and has age so it shows all over wear and has imperfections. Measurements are rough approximate measurements and colors may be off because of lighting.
