Allophane has short-range atomic order, it is a mineraloid, rather than a mineral which was mined Mexico. This specimen shows great under a UV light.


Kyanite, a aluminium silicate mineral often found in groups of light-blue crystals. This beautiful specimen was mined in Minas Gerais, Brazil. A similar variety is also found in Harts Ranges, NT, Australia.


This beautiful translucent specimen of Fluorite was mined from Cave-in-Rock, Illinois, USA and shows a deep purple under good light.


This chunky specimen of Aragonite was mined in Spain and made its way over to Australia where I acquired it from Greg at Blue Gems at the August 2016 Sydney Crystal Show.


Aquamarine can form stunning immaculate crystals, creating some of the most beautiful mineral masterpieces. With immaculate beauty comes a price tag.


Stunning specimen of natural Chalcanthite with small clear blue crystals on matrix. This piece was mined from Buckskin Mountains in Arizona, USA.


Citrine is probably one of the most talked about minerals going around. Is it natural, is it heat treated and does it matter!? From an aesthetic point of view, the golden points on a citrine cluster can look amazing and from a chemical formula point of view, it is still a variety of quartz (SiO2).

Elestial Amethyst

Amethyst comes in a variety of different shades of purple depending on the locality, usually caused by impurities of iron or manganese compounds. This piece is particularly special due to its formation known as elestial amethyst.
