The turquoise exhibits were extensive, and had enough information to interest anyone on your group, whether they are interested in history, geology or how to buy turquoise. It actually has so much information that there is no way to absorb it all.
On the other hand, all the staff dodged questions about Gertrude Zachary (who they refer to as Gertrude Schmidt) and the actual history of the castle. One staff member went so far as to say that she really wasn’t part of the family. Ok, she was only married to Richard Zachary for a year. But she built the castle where the museum is now housed, and it would be polite to at least acknowledge that. Families may not always get along, but trying to discount her role as a business woman, or the collector of many of the antiques on display or the very building we were in left a bad taste in my mouth.
Go to the museum, enjoy the excellent exhibits and learn how to buy turquoise. But take what you are told about the castle with a grain of salt.
