Rocks, gems and minerals - Sunday Stamps II

In 1982 New Zealand issued a set of 6 stamps featuring minerals all of which are found there.

I can only show you two of the set.


Iron Pyrites is mined for its sulphur content and provides 40% of the world's sulphur. Pyrite, iron sulphide, is the world's most common sulphide. It is also known as "fool's gold"

I must confess that I had not heard of the mineral on the 5c stamp.

Carnelian is a variety of the mineral quartz and belongs to the largest class of minerals - the silicates.

The other stamps in the set feature - 
  • 1c Nephrite also known as jade
  • 2c Agate - a variety of quartz
  • 4c Amethyst - also a quartz variety
  • 9c Native Sulphur

I obtained the two stamps illustrated when I was given an envelope from New Zealand which I thought was worth showing again; it carried a lighthouse that would have been right for our theme two weeks ago.
