Why the Fantasia Brand: Fantasia Mining is a USA company located in Massillon Ohio, with a 90,000 sq ft warehouse and over 2,000,000 lbs of stones and stone products in stock. We have been in business since 2010 providing stone related products to stores around the world, and as mine owners ourselves, we care very deeply about the quality of the products that we provide. The Fantasia brand of rough Moldavite is 100% natural and imported directly from our partner mine in the Czech Republic. Stone Size: 0.5" to 1" per piece avg. Stone Weight: 4-6 grams per piece Color: Green - Translucent Note: This item is sold by weight (grams) so as an example, a quantity of 20 is 20 grams total weight and not 20 pieces. The sizes, weight per piece, and colors are averages. It is possible to get pieces outside this range, or with other variances in shapes, color shades, patterns, clarity, translucency, number of pieces or other characteristics which can vary each time natural stones are mined.
