Choosing your Birthstone: Colors and Meanings
Choosing a ring (or any other piece of jewelry) based on your own birthstone – or your loved one’s birthstone – can show that you have put that extra bit of thought into finding something that is special and personal to them.
Most people choose their birthstone from consulting the Modern List of Birthstones for each month or from the Zodiac Sign Gemstones Chart. We show below the birthstones for these together with some information about the colors to be found for each gemstone.
However, as well as the Modern list of birthstones, there are also many ancient and cultural birthstone charts. Some of these birthstone charts coincide with the zodiac sign gemstones; others are totally different. To see some of the further options for birthstones from ancient sources see our Birthstone Chart.
Care should be taken when you are buying your birthstone ring to ensure that the gemstone is
- The best quality for its price; and
- That it will be robust enough for its daily use.
With this in mind, we have provided information on what to look out for when purchasing your special ring. All of this can be found in the various sections below.

Gemstone colors are graded according to their hue, tonal quality and saturation of color. The hue is the type of color and the tonal quality is how light or dark they are. Birthstones need good saturation to enable them to look vibrant otherwise they can look dull and lifeless regardless of how light or dark they are.
Gemstones are also graded by the quality of their clarity and transparency. Many gems have flaws or inclusions that can minimise the amount of light that reflects from the crystal structure of the stone. The better the clarity and transparency, the more light can bounce off the gemstone and enable its vibrancy of color to be displayed.
When buying birthstone jewelry online, it is advisable to check the merchant’s product details for information on the gemstones clarity and overall quality rating to ensure that your ring is of a suitable standard for its price.
Another important aspect to take into account when buying a birthstone ring is the amount of daily wear and tear it is likely to have. Not all gemstones are ideal for rings worn every day. Some are better than others at withstanding the scratching and knocks that invariably occur with normal daily activities. When selecting rings that will be worn regularly then styles that have been designed with durable gemstones are often the best option. Alternatively, if your favorite birthstone is not very durable, then look for rings where the gem is featured less prominently or as accent stones enhancing a larger more robust gemstone.
There are two main elements to a gem’s durability: First the stone’s ability to withstand surface scratching (measured by the Moh’s Scale of hardness) and the extent of cleavage the birthstone contains.
When selecting a gemstone ring that is to be worn daily it is advisable to select one with a stone that ranks high on the Moh’s scale. The hardest and highest ranking gem on the Moh’s scale is the diamond (ranked no 10), with ruby and sapphire (ranked 9). Birthstones with a hardness level of between 7.5 – 8 are still fairly robust for withstanding normal daily activities and these include Topaz, Aquamarine, Beryl and Emerald.
Even though a gemstone ranks high on the Moh’s scale for hardness this doesn’t mean that it cannot be damaged. Many stones have cleavage planes within their structures that can split or shatter when subjected to a severe blow at a weak cleavage point. There are four levels of cleavage: Perfect, Good, Indistinct and None. Gems with perfect cleavage produce a smooth surface along the cleavage plane when it is subjected to a sharp blow. Jewelers use their knowledge of cleavage when cutting precious gemstones in their natural state.
Gemstones with perfect cleavage include: Diamonds, Moonstones, Tanzanite and Topaz. Gemstones with no cleavage include: Agate, Amethyst, Citrine, Opal, Ruby and Sapphires. Depending upon the amount of cleavage a gemstone has it will break perfectly or imperfectly.
Selecting the best birthstone ring should therefore not simply be about the month, the zodiac sign or the color. It is also important to think about the amount of daily wear and tear that the gemstone will need to withstand. For example, diamonds may score high on the Moh’s scale and be resistant to scratching but their perfect cleavage can make them vulnerable to a severe blow.
Therefore, if your choice of birthstone is one where the wearer’s daily activities may put the ring at risk of damage, then it is advisable to avoid designs where the gemstone is set high and exposed. For vulnerable birthstones, look for styles where the gem is set low and protected by the ring’s metal. Channel, V-prong and bezel settings are particular good for less durable gemstones where the ring is likely to be subjected to a high risk of knocks and blows.
In order to help you select the most suitable gemstone for your ring we have created the following chart so that you can see how resistant or vulnerable your choice of birthstone may be to damage.
