Wow Mike, an awesome specimen of red quartz from Dalnegorsk! As both a quartz fan and a Dalnegorsk fan I know that these specimens are highly sought after, and such a large and good one is hard to get. A superb Dalnegorsk classic, I love it!

Nice Wölsendorf classic, good colour! And the cavities seem to be part of a perimorph, do you know more about it?

I would consider both of your Huanggang quartz/fluorite specimens as masterpieces, they combine two of the most beautiful minerals and have an outstanding shape and quality.
Congratulations!
