Information about Gemstones and Pearls



Popular Gemstones


Many of our jewelry items feature one or more gemstones. According to the Gemological Institute of America (GIA), to qualify as a gem, a stone must be beautiful, durable, and rare. Some gemstones (like pearls, coral, and amber) are classified as organic, meaning that they are produced by living organisms. Others are inorganic, meaning that they are generally composed of and arise from minerals. Stones that are identified as synthetic are created in a laboratory (as opposed to natural gemstones, which are created by natural processes without human help).

Here are the descriptions of the gemstones featured in MMA's Silver Star line of jewelry that's available on our site.

 

What are "Rough Cut" Colored Gemstones?

Rough cut stones are a wonderful way to wear gorgeous genuine gemstones at a great price point. These stones go through a chemical process to even and enhance their color and develop their natural characteristics, but with rough cut gemstones the emphasis is less on extensive cutting and polishing and more on bringing out the unique natural features of the stone. Fans of this organic look value the individuality and variety of each gem selected.

Because a rough cut style embraces the natural variations in the stones, designers can get much larger gems at a fraction of the cost. This style is a beautiful, affordable option for wearing large carat weight, 100% genuine stones like emeralds, rubies, and sapphires.



Pearl Jewelry and Shell Jewelry

 

What Are Cultured Pearls?

Almost all pearl jewelry in the marketplace today is made up of cultured pearls. This means that the pearls were produced with human assistance by oysters or other mollusks at a pearl farm (as opposed to being found and collected by divers). To create a cultured pearl, a pearl farmer will trigger the natural process of pearl formation by inserting a small irritant into the oyster or mollusk. The oyster will then surround it with layer after layer of nacre. It is this nacre that gives pearls their characteristic beautiful luster. Creating a cultured pearl can take from 6 months to 3 years, depending on the type and size of pearl, and it requires both constant care and clean, pure water. 

What Types of Pearls Are There?

Cultured pearls may either be freshwater pearls or saltwater pearls, depending on the type of oyster or mollusk that produces them and the climate where the oyster lives.  Freshwater pearls are the most plentiful and affordable type of pearl on the market. They come in a wide variety of shapes and colors, and are sometimes dyed to create a bright colorful look.  Saltwater akoya pearls are round, white (sometimes with a rose overtone), and are often used to make classic pearl necklaces or pearl earrings.

What Is Mother of Pearl?

Mother of Pearl is a type of shell. It comes from the inside shell of a pearl-producing oyster or mollusk. This shell is made up of nacre, the same material the oyster produces to coat a pearl.
