Without jewelry, pearls would be nothing but oyster gallstones and treasure chests would contain nothing but dirty back issues of The Economist. Embrace the power of bling with today's Groupon: for $50, you get $150 worth of fine jewelry and watches at The Richter & Phillips Co. on East Sixth Street. This Groupon may only be used for in-store purchases.

A storehouse of high-quality gems since 1896, Richter & Phillips' stately shop sparkles with a dragon den's worth of diamond earrings, pearl and sterling silver necklaces, tennis bracelets, and backgammon beads. Surprise a long-time lover by presenting her with a suitably decked-out engagement ring and asking her if her sister will like it, or put your old bedazzler to good use by fastening certified loose diamonds to your sneakers. Richter & Phillips also stocks a bevy of fine watches from trusted brands such as Swiss Army, Omega, and Hamilton. Expert jewelers are always on hand to field questions and can give your holiday gift a truly memorable touch by custom engraving it with a heartfelt declaration of love or favorite sitcom catchphrase.
