A Gemstone—also known as a precious stone or semi-precious stone—is a mineral or an organic material which is rare, valuable, durable and beautiful. Others—known as synthetics—are man-made but have very similar properties to natural gems.



Through the ages, various civilisations have set gemstones in jewellery and personal adornment; they have also been recognised by the ancients for their sacred, magical and healing properties. Found in Egyptian tombs and temples, the ancient Egyptians wore them as amulets and charms. Native Americans, Mayans and Aztecs all used gems in their ceremonies. In the Middle-Ages, gemstones were crushed into wine and administered as medicine.



Some cultures associate gemstones with zodiac signs, whilst others have been associated with different months of the year. This custom of wearing birthstones has spread throughout the world, but can be sourced back to Poland in the 18th Century.

This selection varies from country to country, and there may be more than one birthstone; however, below is a list of the most popular selection:

February Amethyst
March Aquamarine
April Diamond
May Emerald
June Pearl
July Ruby
August Peridot
