Astro Gallery - New York Times
Astro Gallery, located at 417 Fifth Avenue in Midtown Manhattan, is hidden in plain sight—essentially a “by‑appointment” gem store tucked behind an unassuming facade. The gallery is the world’s largest natural history shop, spanning around 10,000–12,000 sq ft and packed with minerals, gems, fossils, meteorites, crystals, home decor, and jewelry. It caters to both serious collectors and casual browsers, offering everything from pocket-sized stones to massive amethyst geodes and museum-quality specimens. The tone in the article emphasizes its museum-like quality with educational displays, yet every piece is available for purchase—straddling the line between spectacle and retail.
