Diamonds are forever, that's how the song goes. And women love them, that's for certain. So, make sure you win your woman's heart by purchasing the right diamond ring on this special occasion.

When buying an engagement ring with a diamond, the main thing to look for is not to buy a fake one. Unfortunately, the market is stuffed with counterfeit diamond rings. Ensure that you purchase the ring from a well known dealer, and ask for a warrantee as well. Genuine diamonds have authentic certificates that specify they are true.

The next step would be to look at what specialists call the Three Cs that determine the diamond: the cost, the cut and the color.

Choose the right size. Diamonds are measured in carats, and the higher the number of carats, the larger the diamond is. The larger the diamond, the more expensive that is, but you can ignore this detail when it comes to an engagement ring. A ring with a large diamond is more valuable that a ring with small diamonds that have the same number of carats altogether as the big diamond.

Diamonds are also characterized by a cut. They can be hexagonal, pear shaped, heart shaped, octagonal- all this depends on the original shape in which the diamond was found and the shape chosen by the specialist who has accomplished the cut.

The form does not necessarily contribute to the value of the diamond ring; it is up to your taste only to pick the shape that you like.

Another determiner of a diamond's value is its color. Most people are acquainted with white or transparent diamonds only. However, there are several colors in which the diamonds can be found, and this does not mean that they are fakes or that they are irradiated with different substances. There are genuine diamonds, which can be found in shades of pink, green, yellow, and even blue.

The colored diamonds are very rare, and this leads to the fact that a genuine colored diamond is very pricey. In case you would want a colored diamond ring that does not cost you a fortune, you could choose an artificially colored diamond ring. These diamonds are popular among diamond fans, even if they are not exactly the 'real thing'.

Last but not least, the ring, which is adorned with the diamond, should be to your (or your lover's) taste. There are many models to choose from. There are certain dealerships that will manufacture the exact diamond ring you order. That will take some time, but you will have a unique engagement ring for a unique person.

A good idea is to visit several diamond ring dealerships and decide on the model you want.
