Calcite on chalcedony from Brazil - large cabinet size
Calcite on chalcedony from Iraí, Rio Grande do Sul, Brazil
The 3 large calcite crystals are very stong pink fluorescent, the smaller ones are light pink fluorescent, the chalcedony is purple fluorescent. On 2 of the large calcite crystals is a yellow fluorescent spot.
Unfortunately I can't make pictures of the fluorescence, but you won't be disappointed.
