Birthstone of the Month – Pearl

In honor of the month of June we are going to dedicate this month’s blogs to the mystical pearl, June’s birthstone. Similar to a diamond, a pearl has many different features which make every pearl unique. This month we will go over the history of the pearl, how pearls are created, common pearl terms, as well as pearl care and how to buy pearls, because pearls have been and always will be a classic gift.

Known as the world’s oldest gem, records of the pearl date back to ancient Egypt where they were considered the prized possessions of royalty, symbols of wealth and prestige. Worn by brides during their wedding, they were also said to bring love. Until pearl cultivation began not everyone could afford pearls, then in 1916 pearl cultivation began, which made the pearl available and affordable to all.

Today a pearl is known as a classic piece of jewelry, and a must have in every woman’s jewelry box. Famously worn by Audrey Hepburn, Coco Chanel, Princess Diana and countless others, the pearl is a symbol of elegance.

The only gem grown in a living organism the process of a pearl’s creation is an interesting one. The creation of a pearl is the result of a biological process, a way for the oyster to protect itself against foreign substances. The formation of a pearl begins when a foreign substance slips into the oyster and irritates it, resulting in the Oyster covering up the foreign object with layers and layers of nacre which over time creates a gorgeous pearl.
