The largest groups in this collection are Trilobite (16 pieces). Each piece is listed individually with its own weight and measurements, so two specimens of the same species are priced on their own merits rather than to a common rate.
Locality matters commercially as well as geologically: a specimen labelled with its named mine is a different object to a collector than one labelled only by country, and it prices accordingly. Astro Gallery names the source on every listing where the source is documented.
Four checks settle the question on almost any piece, and they are worth knowing whoever you buy from.
A treated stone is still a real mineral — heating and dyeing are legitimate enhancements, and the problem is undisclosed treatment rather than treatment itself. Astro Gallery answers treatment, locality and condition questions on any individual piece before purchase, by phone on (212) 889-9000 or at customerservice@astrogallery.com.
Astro Gallery guarantees satisfaction on website purchases. A specimen may be returned in its original condition and original packaging, with the packing slip, postmarked within 14 days of purchase, to Astro Gallery of Gems, 417 Fifth Avenue, New York, NY 10016. Cash refunds are processed within 2 weeks of receipt, and store credit is issued immediately on receipt. The buyer pays return shipping, and damage on arrival should be reported within one business day of delivery. In-store purchases follow different terms from website purchases.
Any piece in this collection can also be examined in person before purchase at 417 Fifth Avenue in Manhattan, or at any of Astro Gallery’s four galleries.
