I found a floating Amethyst on a mineshaft

I was testing the last snapshot (21w44a) looking for caves and just try to enjoy the snapshot for a bit and I went to explore a Mineshaft when I noticed a Floating Amethyst, I thought it may be just a render bug but then I saw it was really a generation glitch, here are some screenshots.
Seed and coordinates are provided at the screenshots.
Hope it helps!! Have a nice day o/
