March Birthstone
The March birthstone is aquamarine. Famed for millennia for its pure and even blue or blue-green color, potentially large size, and sparkling clarity, the aquamarine has been a valued gem to many cultures. Aquamarine is a variety of the gem species beryl, making it a close cousin of emerald.
April Birthstone
April's birthstone is diamond. The vast majority of diamonds are transparent, colorless, and show an extraordinary display of well-defined white and multi-colored flashes. Rarely, diamonds also occur in a rainbow of exciting body colors.
May Birthstone
May's birthstone is emerald, a rich green variety of the diverse beryl gem group which must exhibit a dark enough tone and saturation to be called by that name.
June Birthstone
June's birthstone is the pearl. Pearls can only be grown by a very small percentage of mollusk species which may live in either saltwater or freshwater environments. Each species produces a distinctive-looking pearl that is characterized by a specific range of colors and sizes.
July Birthstone
This vibrant red gemstone is the July birthstone and is closely associated with love, passion, and romance. While there are affordable options to be found, the largest and most beautifully colored rubies can be very expensive; the best rubies may be sold for the highest cost-per-carat costs of any colored gemstone.
August Birthstone
Peridot is the August birthstone. It is also sometimes called the “evening emerald” because of its unique capacity to sparkle under natural or artificial light. However, it should not be confused with emerald because peridot has its own distinct characteristics setting it apart from other gemstones.
September Birthstone
The September birthstone is sapphire. Sapphires are members of the gem species corundum. Depending on the exact chemistry of individual stones, sapphires may present a whole spectrum of colors with the exception of red. This is because red sapphires are put into their own category and called rubies.
