Do Find The Right Engagement Ring
Since wearing an engagement ring is a lifetime commitment, make sure it’s the right style that suits your personality, your lifestyle, and your sense of aesthetics. Timeless design is always reccommended. Trendy designs become popular (remember nugget jewelry?) and then they are always replaced by “trendier” designs. Your engagement ring and wedding band should always appeal to you and Classic design will do exactly that.

If your groom-to-be is going to plan a surprise attack, make sure he knows in general terms the styles that appeal to you.  Casual window shopping will help you convey styles that you like, or more importantly styles that you do NOT like. Even off-the-cuff remarks about someone else’s engagement ring can be a good hint to your fiancee.  Asking the mother or the sister style preferences can also be a good way to proceed.

Do you want  to Pick the Engagement Ring
Most brides want their proposal to include an engagement ring, but others are very particular about their jewelry, and want to be part of the buying/designing process.  Perhaps a joint shopping trip to the jewelry store will give the bride-to-be the opportunity to point out several different good possibilities and letting the final choice be up to the groom.  That way, the actual ring is still a surprise and the groom knows he hasn’t made a mistake.
Generally it is a good idea to go Wedding Band shopping together closer to the time of the wedding.  This ring means something entirely different than the engagement ring and each individual needs to have a say on the comfort aspect, design concept, and overall wearability of their band. 
The wedding bands and engagement rings you choose will be one of the most enduring pieces of your wedding day. Not only are they an important element of becoming married, but they are also a long-lasting symbol of your love and commitment. Therefore, you’ll want to choose jewelry that is timeless and high quality. Ultimately, you’ll also want to be an educated consumer who knows what you’re getting for your dollar.
