An engagement ring will be worn for a lifetime. Even if the bride-to-be has her dream ring in mind, it’s wise for the man to seek the advice of a trusted jeweler before making the purchase.

A part of famous love stories (think Grace Kelly and Prince Rainier III of Monaco) since 1847, Cartier recently introduced a new engagement ring collection: Cartier d’Amour. “A new interpretation of the timeless solitaire,” notes Cartier’s Boston Boutique Director, Cedric Tonello, “it is intended to be admired from all angles and the unique setting enhances the center stone with a touch of modernity.” The jeweler’s Set For You by Cartier offering also includes the 1895, the Ballerine and the Déclaration settings. Bridal specialists ensure there won’t be any confusion in selecting a setting and will not only explain the 4Cs (carat, color, clarity and cut), but will also help client’s maintain the balance between the setting and the stone.

“Finding the right ring can be easy and fun,” says Craig Rottenberg, president of Long’s Jewelers, “but the gentleman should take all the time he needs to get it right.” In business for more than 130 years, Long’s starts with a few questions and then focuses on education to aid in the decision-making process. Its Diamond Center, and an iPad app that explains and visualizes the 4Cs, help answer any questions and lead the customer to find “jewelry that matches their style, taste, lifestyle and budget,” adds Rottenberg, who’s noticed two trends in wedding jewelry: custom designs and vintage pieces. Their design software accommodates the first, and for those seeking an antique diamond, Long’s has built a collection of refurbished rings to satisfy the latter.

Although M.R.T. Jewelers space is large—a 7,000-square-foot mini mecca with dual showrooms and a design workshop, explains vice president David Audette—its service is still personal. “We take great pride in our ability to read the prospective buyer and tailor the buying experience accordingly,” he adds. For some gentlemen, this may mean an in-depth discussion of the 4Cs or a diamond’s pavilion and crown angles. “For another, we may have a more relaxed conversation about the personality, hobbies and career of the future ring recipient,” says Audette. Recently, the jeweler, founded in 1918, debuted a new website from which many of its pieces can be purchased, including one-of-a-kind M.R.T. designs.

With an in-house design center, the family-owned Baxter’s Fine Jewelry, has the ability to “design jewelry to the specific needs of our customers,” says Paul Messerlian, CEO. To ensure clients receive the pieces they really want, the company has invested in people and equipment. “We are manufacturers and understand these needs,” he says. “We can custom match a band to your ring, we can make your dream ring come to life, and make the piece of jewelry as unique as the person wearing it.”
