Birthstones that represent your astrological star sign and/or your month of birth have been used throughout history by many cultures, inspiring many myths and legends that still have a bearing on people’s choice of gem today.
A star sign gem, or one of the twelve-month gems, is a great way to celebrate your personal history, however, I would recommend choosing a gem that represents a moment in your life that you are most proud of.
Star signs are associated with certain characteristics and can be complementary to them. Therefore some believe that there is a special significance in choosing a gem for your birth sign to bring luck and ward off negative energies.
Birth month gemstones
The twelve birth month gems have a big cross-over with the astrological birthstones so it is worth looking at both. It is also said that if you wear a particular gem for a specific month, you will be protected by its energy for that period.
Gemstones by colour
In pre-history colour was originally the most important feature of a gemstone, meaning there was no real difference between ruby and garnet. Another historical factor is that some gems have actually changed names over the centuries. For example, Lapis was known as Sapphire, Diamonds would have likely been white sapphire or white topaz.
So frankly, if none of the gems on this page feel right for you, check out crystal gems that appeal to you because of their colour.
These can be an equally supportive base for you, as you have an immediate affinity for them which means you like wearing them and they will therefore be complementary to you – it’s a win-win!
It would be a shame to choose a historical gem that you don’t like or admire because you feel it should represent something that you lack.
History | Gemstones by zodiac
In 46 BC birthstones were associated with the Julian calendar introduced by the Romans under the power of Julius Caesar.
However, when the Gregorian calendar was introduced in the 16th century it had to correct the inaccurate measurements due to the leap years that took place over a 1700-year span.
As you can imagine, these alterations meant that the original alignment of birthstones to the zodiac from the ancient calendars were no longer harmoniously in line.
History | Gemstones by month
The original origin of the 12 gems by month is from the book of Exodus, where the high priestess Aaron of the Israelites is described as wearing a breastplate with the gems inset.
The book of Exodus was written sometime between 600 and 400BC from stories that would have been told by previous generations, in the oral tradition of storytelling.
The first academic research of the Breastplate was carried out by a Roman scholar who he compiled the first list of Birthstones based on his findings c.37-100AD.
History | Pre-Roman gemstone mythology
The idea of birthstones goes back way before the Romans, for example, a thousand years ago the Tibetians created the “Mythical Birthstone List”, and there is also an Ayurvedic Birthstone list that traces back to approximately 1500 BC.
Within many of the myths and legends about what birthstones are, invariably it always comes down to which gem will be the most auspicious for the wearer.
In an effort to organise gems favoured over the centuries a list was created in 1912 by the National Association of Jewellers group, however, the list is ever-growing.
For example, spinel was added to August in 2016, as there is a strong call from jewellers and gem enthusiasts to expand the list of official birthstones, meaning gemstone lovers have a choice that suits their preferences in the modern world.
