A splendid specimen of transparent quartz crystals over blue shattuckite from Sonora, Mexico. The secondary copper silicate shattuckite has a pleasing blue color to dark blue below the qiartz. Above grow sharp, lustrous and water clear quartz crystals. Due to the high quartz transparency the blue shattuckite at the base is well visible and it gives a nice colorfulness. In very good condition – some outside edge contacts. On acrylic base.

Charming!
