A Guide to Birthstones

Birthstones are believed to enhance a persons physical and emotional well-being, in different ways for each gemstone. The history of birthstones spans over a long period of time and involves religious writings, ancient beliefs and more recent folklore.

The Old Testament was the first known reference to twelve symbolic gemstones, they were chosen to represent the 12 tribes of Israel. The stones were mounted on a breastplate, a sacred object worn by the high priest Aaron. Much later in history, the twelve stones were associated with the 12 months of the year and the Zodiac we consult today. There is still a great deal of speculation as to the actual gemstone types used and their respective positions on the Breastplate.

Birthstone jewellery is also used as a Talisman, an object thought by some to possess magic powers and bring good luck. The talisman may be a single unmounted gem or gems mounted in pendants rings or other objects. Gems are also used for amulets, objects thought to give protection against evil, disease and danger. They were common in the ancient past when travellers were known to wear amulets to protect them from dangerous events and feel safe when travelling by road or sea.

The birthstones shown below are based on the modern system, which varies slightly from country to country. There are also alternative birthstones for some calendar months, allowing a greater choice and a more affordable range. For example, the April birthstone is diamond, the alternatives for April include white Sapphire, Goshenite (white beryl) and white topaz, all available at a much lower cost.
