Tumblestones sorted by stone - A-C | Semi precious and gemstone tumbled stones

Some of our massive range of tumblestones - this listing is for stones starting with A, B, or C. We've made the overall stone type most important - so Moss Agate is listed under Agate, for simplicity.

A little about each stone:

• Agate, fossilised Coral - cool coral fossils from Indonesia.
• Agate, banded - simple banded Agates from Brazil, often dyed.
  
• Agate, Blue Lace - one of the more precious types, a gorgeous blue banded Agate.
  
• Agate, Botswana - a grey and white (or pink, grey, and white) banded Agate from Botswana.
• Agate, Crazy Lace - a mixed up brown, pink,red, white and grey partially banded partially brecciated material from Mexico.
  
• Agate, Green Moss - one of most peoples favourites, a clear-milky Quartz with swirly inclusions of Chlorite forming a moss-like frond inside the stone. In some cases the inclusions are very dense and make the stone look almost entirely green.
  
• Agate, Turritella - a bit of a misnomer, actually - this is not an Agate and doesn't contain Turritella! It should arguably be called Elimia chalcedony.
  
• Amazonite - a cute green and white feldspar mineral found around the world.
• Amber - from mixed locations, small chips of polished amber.
• Amethyst - a famous purple mineral available in several grades and colours.
  
• Amethyst, chevron - a purple and white banded mineral often with distinct chevron-like bands of white Quartz.
• Ametrine - a purple and orange combination of Amethyst and Citrine. Often heated in a lab to produce the effect.
  
• Angelite - a very soft duckshell blue mineral - not to be stored with other stones.
  
• Apatite - a common mineral found around the world. This blue material is from Madagascar.
• Aquamarine - technically the name for the blue or blue-green gemstone variety of Beryl. These tumblestones are Beryl, but certainly not a gem grade.
  
• Aura Quartz - a clear Quartz tumblestone artificially coated with layers of metals which cause an iridescence.
  
• Aventurine, green, red - a common mineral with small sparkly inclusions under the surface.
  
• Bloodstone - a form of green Jasper with red inclusions caused by Iron. These often look almost like bloodspots.
  
• Bronzite - a very cool material that looks almost like dozens of layers of shiny rust stuck together. It isn't, though. Also known as Enstatite.
  
• Calcite, orange - a common mineral popular among younger collectors due to its low price and bright colours. Often from Mexico. Too soft to store with other stones.
  
• Carnelian - a common red variety of Agate.
  
• Chiastolite - an interesting stone with a graphite inclusion that often forms a cross like shape.
  
• Chrysoprase - a pale apple green mineral which gets its colour from a small amount of nickel.
  
• Citrine - while natural Citrine exists, this material is almost always heat treated Amethyst, artificially heated in a lab. Real natural Citrine is very expensive.
  
• Coprolite - polished pieces of... fossilised poo! No, I'm not kidding. Dinosaurs, reptiles and marine reptiles all left behind poo which fossilised and could then be polished, cut, or studied.
