I am very familiar with Morgan Hill Poppy jasper. It is really beautiful material but can have fractures and vugs. Fractured cabs are either recut or tossed. Vugs are sometimes hidden and show up when grinding and they can fracture, get better, stay the same or get worse. When a cab is complete and it is attractive, I list with disclosure. A lot of people are not scared off by a vug. Some years ago, some beautiful Koroit cabs were poster here, so I bought a rough parcel from the Koroit guy and what arrived was junk. I either got a full or partial refund. It gave me an opportunity to work with the material and I was able to make 3 cabs. One small one had a lot of opal and the others were a lot of matrix. I made this one and it had no flash, pits on the face and a serious one on the back . I got a question from a potential buyer that I responded to and completed the sale: "I do see the naturally occurring pits and surface cracks that are common in boulder opal. But are there unseen issues that I should be aware of?" He also mentioned that he uses them for macro photography. He received the cab and part of his review was: 'This is a wonderful boulder opal sold at a great price. This purchase really exceeded my expectations." He posted the following picture with the review: I thought the material was not very good because I expect flash and few defects. Someone with more experience was very happy. I'm still not looking for any more.

The use case makes a lot of difference.

Acceptable defects? I know this must be different based on what type of rock it is and what it is being used for. I like to think of my finished rock as it would be judged by the standards for the RTH cabochon challenge, or the World Tumbling contest, in my case just tumbling. I know about the defects for Montana agate by articles written about it and from the many posts and photos on here. So I accept the naturally occurring pits and vugs according to what others say. I found some very unusual poppy jasper that was very colorful but pitted here in the Pacific Northwest where the pits just wouldn't go away with tumbling, so I just stopped working with it. Poppy jasper is really hard to work with and in most cases never comes out perfectly pit or undercut free, but they are rare and cool enough to just accept the problems, for sure. Thanks for posting.
