Once upon a time there was an “amazing?” crystal expert on yt who totally dissed me in a comment about MY knowledge of quartz and crystals in general. She even dismissed the fact that I’d been taught much by Peter, my late friend, who was a crystal expert and an energy healer. Heyho. Such is life.

I’ll bet all the minus £30 that I have in my bank account that she already knows why some of the most famous paintings known are so luminous.

Yes?

And about the Venetian Mills that ground the quartz pebbles.

AND exactly how the likes of Giotto and Raphael and Michelangelo and Giorgione and Bellini and Durer and Tintoretto and Vasari and Veronese and …. used this medium in their work.

And because she is permanently cheek by jowl with a scientifical physicistical, she can explain about the refraction index etc.

I bow in humble supplication to her AMAZING Swiss Chard :o)
