Purchasing a diamond or considering selling one is a big and seemingly overwhelming process. There are two parts to determining the value of your diamond – an appraisal and a certification.
A diamond appraisal determines its current monetary worth. The appraiser will examine both the appearance and the quality of the diamond. Current market value is also taken into account. A diamond’s monetary value can change over time based on the diamond’s normal wear as well as the market value of diamonds overall. It also does not guarantee a price for your diamond, but is an indicator of the potential value of your stone. Your appraisal is important if you want to insure your diamond against loss or theft and, if used for this purpose, should be updated every few years or per your insurer’s guidelines.
A certification is a report that includes the specific measurements and shape of your diamond as well as the specific characteristics of the stone. It includes the diamond’s 4Cs information (clarity, color, cut and carat – check out our December 14, 2021 blog for detail) as well as any imperfections in the stone. A certification does not indicate a diamond’s monetary value. When purchasing a diamond, it is not important to have a certificate, the same information will be in the appraisal, which should always be provided.
The most recognizable certification would come from the gem lab: GIA (Gemological Institute of America). Bridgewater Jewelers would be happy to help you appraise your diamonds if you are looking to sell or updating for insurance purpose.

Despite the prolific use of the terms antique and vintage, in the jewelry trade, they do have specific meanings. This is good news for those interested in truly antique or vintage pieces as it eliminates confusion around modern reproductions of jewelry from specific eras. Often reproductions are poor quality and fail to employ the techniques and materials used during the time period in question. Let’s explore the meaning of the terms antique and vintage.
One of the most Instragrammed sites in the world, Big Ben is the clock tower that was built as part of the Houses of Parliament in 1844 after a fire destroyed much of the Palace of Westminster in 1834. Big Ben first rang on May 31, 1859 and is famous for its accuracy and its massive bell. The name Big Ben actually refers to the great hour bell, which weighs more than 13 tons, but the entire clock tower has been associated with the name. The tower itself was named St. Stephen’s Tower until 2012 when it was renamed Elizabeth Tower at the celebration of Elizabeth II’s Diamond Jubilee, celebrating 60 years on the throne.
Discovered in the mid 16th century, La Peregrina Pearl is one of the most symmetrical natural pearls ever discovered. It was discovered in Panama and turned over to Don Pedro de Temez, the administrator of the Panama colony. Temez carried the pearl back to his Spanish homeland where he gifted it to the future king, Phillip II who gave it as a bridal gift to Queen Mary I of England. When Mary died, Queen Elizabeth I returned it to Spain where it remained one of the crown jewels for more than 250 years.
Did you know that jewelry used in movies is often real and sometimes created just for the movie? Remember the gorgeous ruby necklace presented by Richard Gere to Julia Roberts before they visit the opera in Pretty Woman? The necklace is white gold with diamonds and 23 rubies. Created for the film, the necklace is worth about $1.35 million.
And, could we talk about jewelry in movies without mentioning the Heart of the Ocean, a 56-carat blue diamond in a heart-shaped cut, created for Titanic? Sadly, the necklace never existed. Kate Winslet wore a replica made with zircons during the movie. The necklace was inspired by three famous diamonds that are part of the history of French royalty – the Regent, Marie Antoinette Bleu and the Hope diamond. Celine Dion wore a replica of the Heart of the Ocean during her 1998 Oscar performance of My Heart Will Go On, a 170-carat sapphire necklace set with 65 round diamonds worth about $2.2 million.
