Semi-precious gemstones and beads are mainly made up from pieces of natural minerals which have a lower commercial value than rare and costly gems like diamonds and rubies etc. There are exceptions such as Amber or Jet which are considered to be semi-precious but are not actually minerals. Most mineral gemstone beads are hard where as organic gemstone beads are soft such as Jet, Pearl, Coral and Amber (which is formed from fossilised tree resin). Semi-precious gemstones are often treated to bring out and often enhance the remarkable natural coloured within the rocks. They are then cut and polished to form many different shapes and sizes with both smooth and faceted surfaces. The finished gemstone shapes and beads are used extensively in the jewellery industries throughout the world because of their high aesthetic value.

Semi-Precious - Amber Round Beads Amber is a yellow-orange brown colour and although thought of as a semi-precious gemstone its not actually derived from a mineral but fossilised from the ancient resin from trees. Like pearls amber is an organic gemstone that’s formed from a biological process and has taken millions of years to form. The resin produced by the trees is a strong scented sticky resin that would collect bits of bark, seeds and insects as it ran down the tree trunk. As the resin aged it became harder and darker and formed the amber we know today. Most commercial Amber comes form either the Baltic’s or the Dominican Republic.
Semi-Precious - Aventurine Round Beads Aventurine is a type of quartz that forms when quartz is subjected to intense heat and pressure which causes the rock to melt and combine with other minerals.

The most common colour of Aventurine is green but it can also be found in yellow, orange, blue, gray or brown.
