Hello Again, this specimen is extremely dense and hefty. it has 2 patches of tiny red crystals. the rock also has many tiny pores on much of its rather dull coated surface. there are small and very large windows where the blue crystalline mass within the rock shows its bright shimmer. it weighs 1,210 grams and measures 12x12x6 cm. i forgot where exactly i found it, but it was nearby my home on Long Island.

It looks like quartz with iron staining.Most softer rocks are ground up by time the glaciers got that far south.
