When it comes to jewelry, a little knowledge goes a long way. This introduction to gemstones is as good a place to start as any in your quest to understand and buy quality jewelry.

Jewelry is one of the most popular gifts in the world. Whether you're giving someone an engagement ring, a birthday present or a holiday gift – jewelry is always a welcome sight. Both women and men enjoy receiving precious gold, silver and gemstone jewelry; watches, bracelets, rings, necklaces and earrings are all great choices for either gender. When it comes to gemstones, there are a few more things to consider than when you're just purchasing a precious metal.

First of all, it's important to note that gemstones are often associated with certain occasions. Diamonds, for example, are usually given for romantic occasions, such as engagements and weddings. Colored stones may be given for many other reasons, or just because they appeal to the wearer. Many people choose their colors from a guide to gemstones that lists which stones correspond to which birth months. That way, they can either wear the stone for their month, or a stone representing the birth month of someone they love (ie, children or spouse). Here is a list of which stones represent which calendar months (some months have two stones associated with them):

January – Garnet

February – Amethyst

March – Aquamarine or Bloodstone

April – Diamond

May – Emerald

June – Pearl or Moonstone

July – Ruby

August – Peridot

September – Sapphire

October – Opal or Tourmaline

November – Yellow Topaz or Citrine

December – Blue Topaz or Turquoise

Choosing a gemstone for a gift can also depend on some of their more mythical qualities – some stones, such as amethyst and moonstone, are said to have properties that enhance the wearer's abilities. (Amethyst for energy, moonstone for clarity, as an example.) They also can be chosen for their worth; diamonds are the most valuable of all the gemstones, followed by the related stones of emerald, ruby and sapphire. Other reasons for wearing specific stones can include their association to a part of the world (such as jade for China and amber for the Baltic area), or for various religious and spiritual purposes.
