I am offering a 20 ft container of rough black obsidian (20 tons approximately). Price per container US$18,000 (US$0.90/kg). Two months delivery.

After arrival of the goods in the country port of destination, the customs clearance in the importing country needs to be completed by the buyer at his own cost and risk, including all customs duties and taxes.

We have an inventory of 38,000 tons of black obsidian. Check the video to see the quarry and the material. Average stone sizes is 6 inches x 4 inches x 4 inches. We can also fill up 4 containers with bigger stones (over 10 kgs each).

This is the first time ever that one container is auctioned in www.gemrockauctions.com. The obsidian comes from a quarry in Guatemala, and shipping is from Guatemala.

We have mining and exportation licenses. Laboratory information: density 2.31 g/cm3. Silica (SiO2) 71.92%-75.80%. Obsidian is natural volcanic glass formed as an extrusive igneous rock.Obsidian is hard and brittle; it thereforefractures with very sharp edges, which were used in the past in cutting and piercing tools, and it has been used experimentally as surgical scalpel blades. In Mesoamerica it was also used by pre-columbian peoplewho carved and worked obsidian for tools, knifes and weapons and decorative objects.
