Interstellar Gemstones

By Isabelle Corvin, CG, Staff Gemologist at Panowicz Jewelers

Gemstones are beautiful. Everyone knows that! They are flowers of the mineral world, treasures from deep within the Earth.

Most of the time.

There are some gems that are a special breed of stellar minerals. Interstellar minerals that is!

That’s right, there are some amazing gemstones that come from the stars above, or have been found on other planets. These gems aren’t just rare, durable and beautiful; they are (literally) out of this world!

Opal

Dilamani Black Opal

This incredible pendant by Dilamani Jewelry features Black Opal, which is, thankfully, found right here on Earth!

Opal is comprised of a silica gel substance, usually with a small percentage of water present. The silica forms microscopic spheres that stack upon each other to form opal.

Opal deposits are usually found in cracks and fissures; places where the silica was allowed to seep long ago. Usually, the “gel” is a byproduct of an acidic water-based compound. We know of our opals here on Earth, but what about on Mars?

In 2007, the Mars rover Spirit discovered many deposits of a silica-based rock that looked an awful lot like opals. NASA confirmed it was silica by using false color imaging and the spectrometer, which collects approximately 544 colors (wavelengths) of reflected light to detect minerals on the surface. The minerals are most prominent on outcroppings and in cliff basins in one section of the planet.

These were a surprising and important find on our neighboring red planet because it proves there was, at least at one time, water on the surface.

Perhaps someday they will be able to obtain a sample of this Martian Opal and take a closer look. Will it look like our opals or will it stun us with a different kind of beauty?

For now, they often call it Opaline Silica and eagerly study what they can of this Martian feature as it might hold clues to Mars many ages ago.

Peridot

ColoreSG-Peridot

Though peridot’s remarkable green hue looks out of this world, these sterling silver peridot post earrings by Colore|SG belong to our world.

Peridot is the gem variety of the mineral olivine with the chemical formula (Mg, Fe)2SiO4 – magnesium, iron, silicon, and oxygen. It’s the birthstone of August and is famous for its almost shockingly energetic green color.

On Earth, this gem is found in igneous rocks. Not on Earth, you might see it on a meteorite! The gems have been on pallasite, and around, meteorite impact craters.

The interesting thing to note is that peridot can’t handle super high temperatures, so the outer “shell” of meteorite must have protected it and burned off instead, as it entered the atmosphere.

It is also been observed as interstellar dust. This “dust” is seen in the tails of comets, the disks around young stars, and at the sites of impact craters.

This evidence suggests that the mineral olivine quite possibly was present at the creation of many planets. Perhaps even our own.

Usually, the peridot found on meteorites is small and pale in color, due to the extreme conditions from once it came. GIA laboratories ran a series of tests on the “space” versions of peridot and found key differences in the chemical makeup of the stones, meaning they can always tell if it’s an Earth grown peridot or a visitor from the stars.

The gemstone is often called the stone of sun, maybe that’s a little more literal than we thought.

Quartz and Feldspar

markschneider-quartz

This futuristic pendant features the earthly gemstones bubble quartz, moonstones, and diamonds. Designer Mark Schneider Design won 2nd place for Design Excellence in the 2013 MJSA American Vision Awards.

Quartz and feldspar are two of the most common minerals found on Earth, and makeup not only gemstones such as amethyst, citrine, chalcedony, and moonstone (among others,) but also sand, marble, ceramics, and plastics.

Quartz and feldspar are massive groups of minerals, and since it’s abundant on Earth, we fully expect to see it elsewhere in the universe!

But what might we see if we find these rocks far, far away?

Will we find a bright blue quartz, naturally colored?

A giant moonstone spire that stands taller than a skyscraper?

An entire planet of nothing but crystal?

No one is sure but the possibilities are endless!

The presence of these minerals tells us that other worlds may not be as different as our own, despite appearance. They were all formed in the same universe, after all.

“Diamonds”

Many types of “diamonds,” or something kind of like them, have been found. Some of these minerals are made of carbon but form in a different crystal structure. Since the crystal structure is unique to diamonds and is partially responsible for how tough and durable diamonds are, these stones have a key difference.

Others are small pieces, considered dust. There’s even some that form flat-like sheets, instead of how they form here on Earth.

There’s a bit of a debate if any of these can truly be called “diamonds,” but either way, they are unlike the gems we have here on Earth.

Glass

Multiple forms of glass have been found at impact craters, but the interesting thing about them is that they are often colored. We tend to think of glass as clear, transparent, but the majority of “natural” glass formed by impacts is green! Some of this is called Moldavite.

Discoveries are happening daily about the world beyond our own, and who knows what’s next.

Perhaps someday in the near, or distant, future, we’ll be talking to clients about setting “space” stones into rings, and working on marketing some rare mineral from a million light years away.

With the variety of minerals on Earth alone, the sky’s not even the limit on what we could discover!

Here’s to the rare, durable and beautiful gemstones that make our planet special.

And, apparently, other planets, too.

‘Tis the Season for Stackables, Studs, and Solitaires

The holidays are only a few days away, so if you’re still looking for something super special for the season, the American Gem Society (AGS) suggests stackables, studs, or solitaires. These pieces are always on trend and are regular go-to items in any fine jewelry wardrobe.

Below are some dazzling designs by our AGS members that are sure to inspire. If you need more ideas, you can always count on an AGS jeweler to help. Every year, our AGS members are required to continue their gemological education, staying up-to-date on changes and trends in the jewelry industry. Search for an AGS jeweler near you by clicking here.

Stackables

The beauty of a stackable bracelet or ring is that you can wear them individually, mix and match to change the look or wear them all together. So many options!

Studs

These days, when it comes to studs, the possibilities are endless! You could sport a solitaire diamond or gemstone by day, and then dress it up with an earring jacket by night.

Solitaires

Often a solitaire is presumed to be a round diamond, simply set as a ring or pendant. But today you’ll find these singular stones come in all shapes, sizes, and species—like corundum (ruby and sapphire) and quartz (amethyst and citrine).

Always keep in mind, when purchasing a diamond—whether it’s a loose stone or mounted—to ask your jeweler for an AGS Laboratories Diamond Grading Report. That way you can be confident that your diamond has been consistently and accurately graded by the only nonprofit diamond grading laboratory with the mission of consumer protection. Accept no substitutes. Happy shopping!
