Gem Lore:
Opal - derived from the Latin word ‘opalus’, which translates to ‘see a change in colour’. The romans believed Opal to be a beautiful combination of all the other precious gemstones. Another interpretation in ancient India, considered the opal to be the embodiment of ‘Goddess of the Rainbow’. In recent years, the gemstone has been carved out to symbolise hope and honesty. Precious opals exhibit the optical effect, known as play of colour. The iridescence of red, orange, yellow, green, blue and violet flashes, is due to a combination of diffraction and interference of light.
White Opal's - possess a magical phenomenon termed opalescence. The translucent, pearly white appearance, resembles the sky on a cloudy day. Not many people know, that the cause of a cloudy sky and white opals are similarly linked. The effect merely relies on large particles scattering light. White opals been associated with the meaning of purity and nurturing.
Sapphire - derives from the Latin word ‘saphirus’ and Greek word ‘sapheiros’, which simply translates to the colour blue. This gemstone is referenced frequently throughout Ancient Literature. From being the celestial material given to Moses, that sacredly held the inscription of the Ten Commandments. The ancient Persians, who believed the earth to rest on a giant sapphire, which was then reflected in the sky. To Helen of Troy, who was thought to possess a large star sapphire, the reason behind her desirability. In most recent times, sapphire has come to symbolise wisdom and creativity.

Even the pH level of you skin and the natural oils it produces, can tarnish your gold jewellery.
