It used to be that nothing short of a diamond would do for a woman's engagement and wedding ring, and while a diamond may still be a girl's best friend, other gemstones are rising in popularity. Jewelry has always been a way for a woman to express herself and her personality, so why should bridal sets be any different? Here is a look at five different gemstones other than diamonds to consider for your rings.

Turquoise

If you're more comfortable in a pair of blue jeans and cowboy boots than a skirt and high heels, a turquoise engagement ring might be for you. Turquoise comes in a wide range of blues, and sometimes, it may be specked with copper or aluminum. Pair it with platinum or silver and a couple of smaller diamonds on either side for some added bling. With a rating of about 7 on the Mohs hardness scale (a diamond is 10 on a scale of 1-10), the gemstone will have no problem standing the test of time.

Sapphire

Sapphires are a 9 on the Mohs hardness scale, making them almost as hard as a diamond. They are far less expensive, however. While most sapphires are blue, they can also be found in a pretty pale peach or pink as well as green, yellow, and even white, so if you had your heart set on a diamond but just can't swing it financially, this may be the gemstone for you.

Garnet

Also the birthstone for January, this gemstone comes in at about an 8 on the Mohs hardness scale. Garnets also come in an assortment of colors, but a blood red is the most common. This stone looks great when paired with a gold setting and band, lending a regal look to it.

Tourmaline

This gemstone is similar in color to a rich, green emerald, but it tends to be a bit cloudier. This is a good thing, however, as scratches aren't as obvious over the years. It registers about a 7 on the Mohs hardness scale, and it pairs nicely with both gold and silver settings.

Opal

If you like the look of pearl, which is only about a 2 or 3 on the Mohs hardness scale and isn't suitable for an everyday ring, consider an opal. It has an iridescent sparkle to it, and with a hardness scale of about 6, it will stand the test of time.
