Kai Yin Lo/KYLO Designer Brooch with removable chain

Kai Yin Lo/KYLO designer vintage brooch has two natural gemstones and the designer signature. The gemstones I believe are carnelian and onyx. The gold is KYL’s 925, that’s sterling silver with special plated gold. There are two ways of wearing, with or without a chain with an almost teardrop shaped fire-orange color carnelian. The brooch is about 2” long and the chain with the stone is about 5”.
