We keep costs down by not having a retail store or having a lot of employees. We buy only what will be a good deal to our customers, and have developed a network of some of the best worldwide sources.

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".  Free amethyst or faden quartz with any order.
