1990's Diamond Tanzanite 18 Karat Gold Oval Halo Cocktail Ring

Miami-based Dover Jewelry caters to passionate jewelry connoisseurs looking for that rare or unique piece. The company specializes in estate jewelry styles ranging from Art Deco to modern. It has cultivated an extensive array of unique collectibles, like a 27-carat diamond Boucheron brooch. Its offerings also include stunning three-stone rings, diamond and gemstone dangle earrings and glittering platinum tennis bracelets.

Now a second-generation jeweler, Dover Jewelry was established to meet the growing demand for fine antique and vintage estate jewelry. The company defines estate jewelry as any piece that has been previously owned. Part of the appeal of estate jewelry is that, in many cases, gorgeous pieces cost roughly a quarter less than they originally retailed for. However, quality pieces from reputable jewelry houses still maintain their beauty and exquisite sparkle.

Dover Jewelry is known for sourcing estate jewels from the world's most renowned designers. Just some of the creators in the company's large collection include Bvlgari, Tiffany & Co, Piaget, Jaeger LeCoultre and Cartier. The jewelry is purchased from bank trusts, charities, attorneys, liquidators and private clients.

Engagement rings are among the most popular pieces in the Dover Jewelry collection. The company carries exquisite rings from numerous time periods. Buyers can choose from Art Deco rings from the 1920s and ’30s, mid-century modern rings from the 1950s and even early Georgian rings from the 18th century.
