 Amethyst - drop             

We specialize in Gem Minerals, Quartz, and especially Amethyst.  Other gems we carry include Aquamarine, Opal and Tourmaline.  New finds include Amethyst from Guerrero and Vera Cruz Mexico, and Tata, Morocco.  Faden Quartz from South Waziristan, a Tribal Area in Pakistan. We consider Faden Quartz to be an amazing demonstration of piezo-electric properties utilized during the growth of these complicated yet aesthetic formations almost unrecognizable from normal habits of Quartz.

We have acquired select Quartz specimens from the Dave Daniel collection, many of which we sold to him in years past, and they are worthy of being in any top collection. If you're looking for Chrysanthemum Stones, we have a huge selection in sizes from 1 inch to 2 feet.

Our prices are based on the idea that a collection of minerals in good quality and variety should be affordable to the average person.  A good idea for any collection is to stick to a certain size, "thumbnails" fit inside of a 1" cube, miniatures fit in a 2" cube, and anything larger is small cabinet size, up to a 4" cube, or cabinet size 6"?,  or large cabinet size over 6". 


From the Federally Administered Tribal Areas, Pakistan we have a large shipment of high-end Faden Quartz, with  many rare specimens including groups with scattered Brookite crystals.  New crystal habit of Epidote from Baluchistan, Pakistan, hundreds of crystals in stock-wholesale inquiries for quantity invited.

See our Vanadinites from Morocco and Arizona (Minerals H to Z), and NEW! Very good pseudomorphs of Dolomite after Aragonite from New Mexico. (Minerals A-G)

Lots of Aquamarines from $25 on up (Namibia Minerals, Afghan-Pakistan Pegmatite section and in Minerals A-G, under Beryl, var. Aquamarine)
