I see a 23 in my rose quartz tumble stone

I have been praying , meditating and affirming with my rose quartz, aventurine and citrine since a few days back. I keep them around the prayer candle as I pray, I hold them on my palm as I meditate and keep the rose quartz on my chest when I affirm. When I am busy I would keep them near my laptop and play Buddhist mantras or binaural beats .

I have been noticing some changes inside the rose quartz but thought it was for body heat. Then today I checked it properly and noticed there is number 23. It is very clear.
At a another part of the crystal there is a “J” which also looks like a”3”.

Has this happened to anyone? Is 23 a bad number?
