This makes amethyst earrings, necklaces, pendants or rings the perfect gift for anybody born in this month and under this sign. Amethyst jewellery is also the appropriate for fourth and sixth year anniversary gifts. Given its mesmerizing purple hue, amethyst earrings and necklaces are perfect for dark-coloured hair. Australia also boasts very dark amethysts that tend to be much smaller in size, but this is not always the case.Amethysts will sometimes have some kind of heat treatment to enhance their colour. It was also a favourite of the legendary Russian Empress Catherine the Great and figures as a centrepiece of the British Crown Jewels. Therefore, because purple is the colour of royalty, wearing an amethyst ring or broche shows that you are special.However, extreme heat or light can turn amethyst stones into yellow so it is important to store them away from any strong heat or light sources.Amethyst is classified as quartz and is the most highly valued variety of quartz available. It has always been a highly prized gemstone and figured prominently in the crowns, sceptres and various artefacts of royalty throughout history. The ancient Egyptians and Greeks thought it possessed everlasting properties and could even extend the reign of a ruler. Any type of amethyst jewellery would also match perfectly with a purple dress or gown.Part of the appeal of the purple stone is because of the wide variety of amethyst. In fact, amethyst is not only found in Brazil but also found in Argentina, Bolivia, Uruguay and across South America, as well as in Zambia, Namibia and other African countries. South American amethyst tends to be larger in size and lighter in colour than African amethyst stones.
