Gemstones Personified! Who Is YOUR Gemsona?

While enjoying one of our favorite pastimes (looking up fun gemstone facts, of course!) we randomly stumbled across a term we had never encountered before: “gemsona.” In classic internet fashion, we soon ended up clicking on links that led to other links, until we finally found out what the term was referring to: gemstone-inspired characters, more specifically from a cartoon called Steven Universe (Cartoon Network). We soon learned all about this adorable animated show, and the cast of awesome gemstone super heroes!

Wikipedia’s brief setting & synopsis of Steven Universe:

“The series is set in the fictional Beach City…on the American East Coast, where the Crystal Gems live in an ancient beachside temple, protecting the world from evil. Ageless alien warriors, they project feminine humanoid forms from magical gemstones that are the core of their being. …[Steven is] a young half-human, half-Gem boy who inherited his gemstone from his mother, the Crystal Gems’ past leader Rose Quartz. As Steven tries to figure out his gradually-expanding range of powers, he spends his days with his human father Greg, his friend Connie, the other people in Beach City, or the Gems.”

We decided to find out which “gemsonas” corresponded to each of the birthstones of each BDB staff member. Some are original characters from the Steven Universe TV show, while the others are creations by Dou Hong, a character designer at Nickelodeon, who has created an entire cast of characters and features them on his fan art blog.

Underwater Gems: Fascinating Facts About Pearls

Coolest news story of the month: a fisherman in the Philippines recently revealed that he had been keeping the world’s largest pearl under his bed for the past 10 years. The monster pearl is one foot long, over 2 feet wide, and weighs 75 pounds!

Despite its gnarly appearance, the pearl has been declared to be worth over $100 million. The fisherman said he found the pearl in a giant clam while out fishing over a decade ago.

When we read this story here at Blue Door Beads, our first thought was “Holy moly! That thing is crazy huge!” The, our second thought was, “Huh…I thought only oysters produced pearls…?” And that got us thinking some more: what else don’t we know about pearls? Turns out, quite a bit. But now we’ve done some research and are ready to share some really interesting pearl facts with you!

Besides oysters, what other types of critters produce pearls?

Many salt- and freshwater mollusks, not just oysters, produce pearls. They may be formed in mussels, conchs, cowries, and scallops — to name a few — “and come in a rainbow of colors, depending on the species of mollusk.” (nationalgeographic.com) Although fairly rare, even giant clams have produced their fair share of pearls, including the Pearl of Lao Tzu and the as-yet-un-named pearl pictured above.

What exactly is a pearl?

It’s “an adaptation to get rid of a piece of schmutz,” explains Paula Mikkelsen, a biologist who studies mollusks at the Paleontological Research Institution in Ithaca, New York. “The mantle [the fleshy part of the shell] pulls calcium carbonate from the water and layers it around the intruding irritant” in an attempt to relieve the discomfort (nationalgeographic.com) The irritant is most frequently organic material, parasites, or even “damage that displaces mantle tissue to another part of the mollusk’s body.” These small particles or organisms can end up inside a mollusk when the shell valves “are open for feeding or respiration.” (www.wikiwand.com) In the photo below, you can see what a natural pearl looks like when cut in half:

The layers of nacre wrapped around the nucleus resemble a jawbreaker cut if half — although it’s not nearly as tasty-looking! Most pearls are a made of a combination of calcium carbonate, aragonite, calcite, and an “organic horn-like compound called conchiolin.” (www.wikiwand.com)

The reason why you don’t find a pearl in every wild mollusk is because, for the most part, mollusks are able to open their shells to expel any irritants. Scallops can even open their shells rapidly enough that they can travel quickly by “clapping.” (Here is an amusing short video!) This is why pearls used in the jewelry industry typically come from mollusk farms, where the critters can not only have uniformly-shaped “irritants” inserted into their shells — resulting in more uniformly-shaped pearls — but they can also be kept stationary (i.e. have their shells kept closed) by having nets placed over them.

Below is a diagram of the difference between a cross-section of a non-natural pearl that had an already-large round bead inserted inside it (usually made from a polished sphere made from a freshwater mussel shell), and a cross-section of a natural pearl that built its size up over time with many layers of nacre (pronounced NAY-kur):

So, while we’re on the subject…

What’s the difference between cultured pearls & natural pearls?

Turns out, in the modern-day jewelry and bead industry, almost all pearls are cultured pearls. This means they were created through human intervention of some kind, not created on their own out in the wild. Cultured pearls are supervised throughout their development; those supervising must ensure that the mollusk receives the food it requires and the surrounding water temperature remains consistent and pollutant-free. Consistency in these areas means pearls can be grown to be the same color, size, and shape. Cultured pearls can be either saltwater pearls or freshwater pearls.

To break it down, there are three types of saltwater cultured pearls, most of which can only be nucleated with one pearl at a time:

1. South Sea Pearls

South Sea pearls come in two colors: white and black. The white pearls are primarily cultured in the waters of northern Australia, the Philippines, and Indonesia and can vary from white, to light yellow, to gold (usually from the Philippine and Indonesian waters) from white-to-silver (usually from the Australian waters.) The black pearls are found “over a wide area from the Cook Islands to the Gambier Islands in French Polynesia.” (www.missjoaquim.com)

2. Tahitian Pearls

These are considered some of the most beautiful pearls in the world, ranging in color from charcoal gray to dark green and black. Tahitian pearls are only produced by the black-lipped oyster, which is only found around Tahiti and the French Polynesian Islands. The oyster itself is quite large, as much as 12 inches across and up to 10 pounds, which results in larger-than-average pearls. (www.missjoaquim.com)

3. Akoya Pearls

Considered to be the classic cultured pearl type, Akoya pearls are cultured in south-western Japan and China. Akoya pearls typically range from soft pink to “creamy silver” colors. “The Akoya breed of oyster is the smallest pearl-producing oyster used in pearl culturing. The resulting pearls also tend to be smaller, ranging in size from 2mm to 11mm and are consistently round or nearly round,” making them highly coveted in the jewelry industry.

The term freshwater pearl refers to a wide range of different shapes of pearls (such as potato-shaped, rice-shaped, coin-shaped, and many more), but can be summed up with one main definition: freshwater pearls are cultivated in mussels that live in fresh water lakes and rivers rather than oysters that live in oceans. The nacre of high-quality freshwater pearls does not typically have the glossy finish of Akoya pearls, “and they are evaluated on separate quality scales” than the chart pictured above (www.pearlparadise.com). Quite frequently, freshwater pearls are funkier in shape because, instead of inserting a perfectly round bead into the mussel, cultivators often add “a tiny piece of mantle tissue from a donor shell”; since the mussel is adding nacre to a non-solid item, the result is an irregular pearl. (www.wikiwand.com)

Which pearl colors are natural, and which are enhanced?

Pearls can commonly be found in a wide range of natural colors, including white, pink, silver, cream/ivory, and yellow. Pearls in darker colors (such as light brown, chocolate brown, green, blue, black, and purple) can also be found naturally, although they are much more rare. If you come across pearls that are in this darker color family and are inexpensive (i.e. less than a few hundred dollars), chances are the pearls have been enhanced with a bleaching-then-dyeing process. Check out the pictures below to see the wide variety of both traditional and non-traditional pearls that can be found in a variety of mollusks from around the world!

We hope you have enjoyed learning more about one of nature’s most interesting creations, and we also hope that the next time you come across pearls of any kind, you’ll think of the fascinating circumstances that helped make them possible!

One of the rarest natural pearls in the world, conch pearls are typically only found in 1 of every 10,000 conch shells. Very few of these pearls possess the brilliant, bright pink or red color that is so highly coveted; most range in color white, to beige, brown, yellow, or orange. The equally rare flame pattern is also a highly desired featured of conch pearls.

Melo pearls come from the Indian Volute (a.k.a. Melo Melo), which is a giant sea snail found in the waters of Vietnam, Burma, and Malaysia. Melo pearls are not only typically very large (400+ carats), but also range in color from papaya orange to shades of yellow, beige, brown, and white.

Clam pearls, like conch pearls, are also coveted to their flame patterns. Like Melo pearls, they are often quite large -- the bigger, the better!

Quahog clams are extremely common, and can be found from as far north as New Brunswick, Canada and as far south as the Gulf of Mexico. However, their pearls are very rare, and the very valuable lavendar pearls even more so! Check out this fun story about a cop from MA who found one of these treasures in his clam chowder!

All That Glitters – Heat-Treated Gemstones

A couple of years ago, during our annual buying trip to Tucson, AZ, we noticed a trend at A LOT of gemstone booths: brilliantly-colored quartz crystals, some with vibrant aurora-borealis-type finishes. We thought they were cool from the first time we saw them, and their popularity has only grown since then — these quartz crystals continue to be one of the top-selling bead types at Blue Door Beads!

Here's just a taste of the wide variety of aura quartz we sell in the shop!

Although we have had these crystals for quite some time, it’s only been recently that people have regularly started asking us what is done to the crystals to turn them such brilliant colors. Perhaps the summer sunshine has led people to create more colorful jewelry, so they naturally gravitate toward these shimmery little guys — or maybe folks have just become more inquisitive! Whatever the reason, we soon realized that we needed to find out more about the process of creating what we have since found out is referred to as aura quartz.

Aura quartz is created through a process called vapor deposition: clear, natural quartz is heated to1600 °F in a vacuum, and then vapor from a specific mineral (see list below) is added to the chamber. The atoms from the mineral “fuse to the crystal’s surface, which gives the crystal an iridescent” metallic sheen in a wide variety of colors, depending on the mineral used. (HibiscusMoon Crystal Academy)

The International Gem Society explains in slightly more scientific terms how the process takes place, but the two most important things to keep in mind (we believe) when using/buying aura quartz are:

1.) Vapor deposition is a permanent way to “coat” a crystal. The less-than-one-micron-thick metallic coating will not chip off because the mineral has been molecularly bonded with the surface of the quartz.

2.) Exposing natural crystal to such intense heat, combined with certain mineral vapors, can make the stones extremely brittle. The one exception to this fact is the variation of modified quartz called “flame quartz” or “rainbow quartz.” These quartzes “have been enhanced with a combination of titanium and gold. Titanium molecules are bonded to the quartz by the natural electrostatic charge of the crystal in a process known as magnetron ionization…since only electricity is used to deposit the titanium layers and create these colors, very little heat is involved and the integrity of the crystal is maintained.” (Wikipedia) Good to know!

Here’s a list of some of the more common types of modified quartzes, along with the various minerals that give them their distinctive colors once bonded to clear quartz:

  • Amethyst Aura Quartz (purple) –  magnesium & platinum
  • Angel Aura Quartz (bluish-silver) –  platinum and silver, but also sometimes gold or other trace metals.
  • Apple Aura Quartz (bright lime green) – nickel, which gives the stone a bright yellow-green color reminiscent of Granny Smith apples.
  • Aqua Aura Quartz (bright blue) –  gold
  • Champagne Aura Quartz (a metallic brown-gold) –– gold, iron, and platinum
  • Cobalt Aura (dark blue with an iridescent sheen) –  cobalt
  • Copper Aura Quartz (metallic copper) – Pretty self-explanatory: clear quartz bonded with copper
  • Kiwi Aura Quartz (teal green) – gold and silver, or platinum
  • Melon Aura (orange) – copper, gold, and iron
  • Opal Aura Quartz (clear with opalescent sheen) – platinum
  • Rainbow Aura (a range of colors, all with a dark iridescent sheen) – titanium and/or niobium
  • Ruby Aura (fuchsia) – made with gold, silver, and platinum
  • Sunshine Aura (bright yellow) – made with iron and/or platinum, and gold
We think amethyst aura quartz is one of the prettier varieties!
