I don't know the brand, but I bought it at Ala Moana. Please understand that these are used items. The necklace chain can be used on its own, and the two pendants can be layered, or you can put them on separately for different arrangements. The pendants are pink gold and yellow gold. There is no engraving on the pendants, but I believe they are definitely K14. The chain and ring are 14k stamped. I deliberately chose a simple ring.
