Description
Hold a slice of deep geologic time in your hands. This double phantom Tamil Nadu quartz formed over half a billion years ago, long before plants, animals, or anything familiar existed. Its hematite phantoms record shifting conditions in superheated, iron‑rich hydrothermal fluids: a dense, dark hematite layer from a high‑oxygen pulse, followed by a lighter “dust” phantom from a weaker one. These phantoms aren’t surface features — they’re ancient chemical signatures sealed during growth, a rare, clear record of a changing Precambrian world preserved inside quartz for over 600 million years
There is a double termination and sparkling druzy on the reverse side. This crystal has a few dings along the edges, and at the tip, as expected from a specimen this old.
Size: 43 x 23 x 17 mm. 28 grams
From Karur District, Tamil Nadu, India.
