Sterling silver 925 is made up of 92.5% fine silver and 7.5% of other metals, typically copper. Both the fine silver and other metals are then blended to make sterling silver. This process provides the strength and stabilises the metal to provide the perfect material to create jewellery that will last a lifetime.
My sterling silver is sourced from an environmentally conscious supplier that uses the latest technology and vast experience to manufacture scrapped silver rather than brand new mined raw material where ever possible. They buy the silver and (other metals) from existing jewellers and refine the silver back into pure silver.
This environmental approach extends into the advanced manufacturing equipment they use, reducing emmissions, using recycled water and lowering their carbon footprint. The final product of recycled sterling silver is a far more superior and environmental product.
Over time the other metals within the sterling silver will darken called "Oxidising" or "Tarnishing". Depending on the jewellery and your own personal preference, this effect can compliment the piece of jewellery with age or if you prefer to give it a clean.
Sterling silver can always be cleaned and re-polished back to its original glory. Gently use a silver cloth and polish around the stone. Another way is to take it to your local jeweller.
