Vintage Native American Hummingbird Brooch/ Pin RL

Wow, what a beautiful piece. Native American brooch in sterling inlaid with opal. I believe this is Zuni. Trademark is RL. There are 2 Zuni artists that used RL and I am not sure which one this is. Zuni often uses synthetic opal and I do not know if this is synthetic or natural. The price reflects the unknowns. Excellent vintage condition. This piece will come in a drawstring pouch. M
