S0524 Azurite on Malachite. $130 inc free post.
From Milpillas Mine, Cuitaca, Mun. de Santa Cruz, Sonora, Mexico.
3.3 x 2.6 x 1.5 cm
A cluster of well formed, electric blue azurite crystals to 1cm, grown over fibrous chatoyant malachite. The azurite crystals glow with a bright, glossy luster and incredible colour. Sits well for display. Arguably this locality has produced some of the best azurite in the world. The source of this material is has been closed since 2012. This is hard to find and very expensive now.

S1067 Indochinite Tektite. $40 inc free post in Australia
4.6 x 2.0 x 1.7 cm From Vietnam
Asia's version of moldavite.
A nice black teardrop shaped tektite with lots of interesting surface grooves. The shape shows the direction of travel through the atmosphere with the smooth leading edge on the widest end. These were formed 780,000 years ago from the impact of a meteorite which melted the earths crust on impact and ejected this glassy material into the atmosphere. This is in good condition and would be suitable for a nice pendant. Happy to take $10 off per item on multiple buys.

Left handed quartz.
4.9 x 4.3 x 2.8 cm

These are not your average quartz crystals. The crystals are quite bright and they have some interesting S faces indicating left handed growth as explained in the attached diagram. In good condition with just a small amount of microscopic chips. The base is contacted but this does not show, as the crystals sit nicely for display. Happy to take $10 off for each item on multiple buys. The diagram attached is coutresy of the quartz page website. Who would have thought this is a thing.
