The colours and names are wonderfully poetic, and, even without knowing the geology behind them, they intrigue me. Quartz, malachite, smithsonite, berthierite, freibergite; sparkly with points and nodules; bright hues of blues, greens, reds and purples from Wallaroo, Burra Burra, and other places in South Australia.
5 Special Rocks:
Fluorescent rocks from the Sterling Hill and Franklin mines in New Jersey. They really do glow in the dark! Malachite - how beautiful is that!
Gypsum - probably not as soft and fluffy as it looks Someone has organised these colourful pebbles in a way that appeals to my OCD nature. Opalised shells from a piece of ancient sea-bed.
