TUMBLED GEMSTONES

WE OPERATE A STANDARD CHARGE FOR OUR TUMBLED GEMSTONES. YOU WILL NORMALLY RECEIVE MORE THAN ONE STONE. PLEASE NOTE THAT AS OUR STONES ARE ‘NATURAL’ THEY MAY NOT MATCH THE PICTURES EXACTLY. THE PICTURES ARE REPRESENTATIVE OF THE STOCK WE HOLD IN THE SHOP. Also available are our FREE gemstone information sheets. These are supplied in pdf format so you can print them out. They are attached to each tumble stone page. If one is missing, it means I am still compiling the information.
