Band- In terms of band metal, you have several choices. You can choose 14K or 18K gold (white or yellow), platinum, and titanium. Gold is considered to be the more classic and traditional. Platinum is very popular, more rare (more expensive) than gold, and sure to out live other metals in terms of wear and tear. Titanium is not as popular as the other metals, but excellent for people who are not used to wearing jewelry or have sensitive skin.

Settings- The setting refers to how the diamond is mounted to the band. A solitaire setting is most popular because it reflects the most light and reveals more of the diamond. However, it is not recommended for women with active lifestyles due to susceptibility to damage. Settings that may suit an active woman are channel, bezel (where the diamond is under the band), and flush.

Diamonds- Now on to what may prove the most difficult decision you will make; the diamond. Become acquainted with the 4 Cs: Cut, Clarity, Carat, and Color.

Confused? Observe what jewelry when ordinarily wears. Does she wear a lot of silver or white gold? If so, she would probably kill for a platinum engagement ring. Ask her friends and family (women friends and family, the men will be as lost as you are) for suggestions. To get her ring size, trace the inside circle of a ring she owns on a piece of paper and take it in to the jewelry. And above all, enjoy shopping for the engagement ring, if she says "yes" you will find yourself in the jewelry store more often.
