How To Buy Her the "Right" Engagement Ring

Diamond engagement rings are quite possibly the most important jewelry purchase a guy will make in his lifetime (let's hope it's only once in his lifetime!). Hey, if Howard Stern can do it, so can they. But it's true most men don't know the first thing about buying jewelry - let alone THE jewel.

Ladies, here are some tried and true tips you can sneak under his nose to help nudge him in the right direction. And for the guys out there, this one is for you!

• Know the Four Cs - Cut, clarity, carat and color are the main factors that determine the quality of a diamond and thus, its price. It's critical to educate yourself in each of these areas before you start shopping.

• Do your homework - shop around, look at stores' Web sites, ask trusted friends and relatives where they buy their jewelry, do jewelry research on the Web. In other words, arm yourself with as much information as possible before you're ready to make the purchase.

• Know her style - pay attention when she admires someone else's engagement ring or a ring in an advertisement; ask her friends and family what she likes. Look in her jewelry box; notice the style of jewelry she already wears. Also note the kind of metal she prefers (yellow gold, white gold, platinum). Go shopping with her at the mall and browse by a few jewelry stores; you'll get to see first-hand what really catches her eye.

• Find her ring size - Just imagine - you pop the question, she happily accepts, she starts to put the ring on - and it doesn't fit. What a letdown. You want that magic moment to be perfect. So either get a ring from her jewelry box and bring it with you, or make an impression of her ring in soap or clay, or trace the inside of her ring on a piece of paper, or even put her ring on your own finger as far as it will go and mark that spot with a pen. A jeweler can get an accurate measurement through any of these strategies. And of course, you can always ask one of her best friends or relatives for her ring size - just be sure you choose someone who can keep a secret.

• Have a budget in mind, but be flexible - Diamonds are available in a range of prices, so you're certain to find one that suits your taste and budget. Once you understand the Four Cs, you'll be able to find a stone that represents the best value, based on the combination of color, cut, clarity and carat weight you desire. But don't automatically pass up the "perfect" ring just because it's more than you planned to spend. Remember that this is an investment that will last a lifetime - and it won't depreciate in value. As for how much you should actually spend, consider the commonly accepted guideline of two month's salary. However, this is only a directional tool to help you establish a budget.
