A mistake was made fulfilling my order and the nozzles were shipped separately from the hotends. A representative reached out the next day and let me know about the issue and how they had chosen to resolve it.

I had to assemble the nozzles and hotends. No problems yet. I have been a big fan and customer of DUROZZLE for a few years, and I don't think any nefarious motives were at play here. They offered me a generous discount on my next order after I reported that a diamond nozzle broke, and I've been happy with their products. 4.5 stars on this order. I subtracted half a star just for the inconvenience.

I received my Durozzle Diamond nozzle a couple days ago and have printed in PLA, PCTG, and ASA so far with it and I can say that it allows me to get my hotend up to the required temp for a perfect ASA print while being able to handle the more pedestrian PLA and PCTG. I would like to try nylon next and eventually CF Nylon with this hotend. So far so good.
