Opal and tourmaline from Gem 2000.

When it comes to color choices, October’s birthstones give you some amazing choices. Whether you choose opal or tourmaline, you’ll get a display of exciting and intense colors, making them popular choices for jewelry designers and collectors.

Opal

The name “opal” derives from the Greek opallos, meaning “to see a change (of color).” They range in color from milky white to black with flashes of yellow, orange, green, red, and blue. An opal’s beauty is the product of contrast between its color play and its background.

Opal is a formation of non-crystalline silica gel that seeped into crevices in the sedimentary strata. Through time and nature’s heating and molding processes, the gel hardened into the form of opals. The opal is composed of particles closely packed in spherical arrangements. When packed together in a regular pattern, a three-dimensional array of spaces is created that gives opal its radiance.

Approximately 90 percent of the world’s precious opal comes from Australia. The following are other countries that produce precious or fancy varieties: Brazil, Mexico, United States, Hungary, Peru, Indonesia, Honduras, Guatemala, Nicaragua, Slovakia, Czech Republic, and Ethiopia.

Each opal is totally unique, like fingerprints!! To get a really good look at the opals in these designs, click on the images below for a larger view.

Tourmaline

Since tourmaline is available in a wide variety of colors, it is ideally suited to almost anyone’s taste. It is known for displaying several colors in the same gemstone. These bi-color or tri-color gems are formed in many combinations; the gemstones with clear color distinctions are highly prized.

Tourmaline is found in many localities including Brazil, Afghanistan, East Africa, and the USA.

The following designs feature the varying hues of tourmaline. Click on the images to see a larger view.

As summer stretches out toward its final dog days, and the thermometer keeps bobbing toward the high end, you are probably feeling the need to cool down. We have some nice ice to help. As usual with us, it’s the jewelry kind of ice.

Let’s look at five amazingly lovely pieces of jewelry we’ve recently featured on our AGS Facebook page to help us take our minds off of the temperature.

First up, these blue topaz and peridot earrings, and blue topaz pendant, from Goshwara are as calming and cool as the ocean itself.

Staying with the light blues, we love this custom engagement ring from Tacori:

Let’s keep the light blue theme going, with this big, beautiful zircon ring from Carizza:

Straying from the lighter blues, let’s get a little deep, as in the deep violet hue of this Tanzanite beauty from United Color Gems.

UGCLast, but certainly not least, imagine this blue-green sapphire from Gem 2000 in the style of your choice. What would you do? A pendant? A solitaire ring?

Garnets – Warm, Strong & Mysterious

By Isabelle Corvin, CG, Staff Gemologist at Panowicz Jewelers

Happy birthday, January babies!

Born the first month of the year, you get to start with a celebration of life. Ignore the dreary weather with a warm garnet as your birthstone!

A somewhat under-appreciated jewel, garnets hold a mystery and allure all their own. A group of closely related species, the garnet family of gems is vast and varied.

  • Everything from classic Pyrope and Almandite; the traditional reds, from dark to light, sometimes slightly brownish, to Rhodolite, a shy little stone with flirty edges of purple added to red
  • Then there are members like cool Tsavorite, the vivid to minty green rebel striking out and being different
  • Demantoid, the fun-loving gem in yellowish-green colors with fire like a diamond
  • Don’t forget Spessartite, the flashy and robust gem of bright orange
  • And Hessanite, a softer, “honey” color, often hiding amid the rest of the group
  • In fact, Garnets come in every shade BUT blue!

Garnets in a variety of colors by Underwood’s Fine Jewelry.

Throughout history, garnets have been known as stones of warmth, strength, and mystery. The most common color, a deep red, was popular in many cultures and used in a variety of items—not just jewelry.

It was the most popular stone for adornment and inlays in the late Antique Roman period, and a strand of garnet beads was found in an Egyptian tomb dating back some 5,000 years.

It was said to be a stone of valor, that wearing it as an amulet gave someone strength and enhanced bravery. It was also connected with love due to the color, and no surprise, it was associated with the element of fire.

There is a legend that Noah didn’t use lanterns in the Ark—he hung garnets. They were said to glow due to their inner fire and throughout the entire voyage of the ark, stayed lit.

In more modern times, garnets are associated with Capricorn, the zodiac sign, and are believed to help with strengthening both emotions and the physical.

In a more science-based outlook, garnets are used as abrasives in many fields.

Garnets are one of the few gems that display their full, natural color; no treatments are done to enhance or alter them.

Depending upon the type of the garnet, they can be found in many locations around the globe. They usually form in a cubic structure, like squares piled on top of one another.

Garnets are anything but plain or ordinary, and with a wide range of colors to choose from, there’s a member of the family that’s right for everyone. It shines on after years and carries with it ancient history.

It’s a pretty bauble and a treasured talisman. No matter how melancholy the weather may be this time of year, you can rest assure that a garnet will brighten up your day!

The American Gem Society’s Director of Marketing wanted to show off her favorite pieces of jewelry which happen to feature garnet! The earrings and ring were both designed by AGS member, M.J. Christensen.

 

Looking at Diamonds in a Different Light

/ americangemsociety / Leave a comment

Diamonds have been celebrated for centuries as a symbol of love and status and have been revered throughout the centuries. No wonder there are literally volumes of references to diamonds in fiction and historical tomes.

Though April is in our rearview mirror, we just can’t quite let go of our favorite gem, and in thinking about our obsession, three thoughts struck us that show how special diamonds really are:

Diamonds are the result of both nature and man. They come from the earth, but diamond cutters, who are skilled artisans, turn diamond rough into beautiful works of art.

Case in point: this masterpiece from Forevermark.

Diamonds and plants both need light. Plants need light to live. In a way, so do diamonds. The way light travels through a diamond creates sparkle. A well-cut diamond will have more sparkle than one that is poorly cut. Gemologists often refer to this sparkle as “life.”

A well-cut diamond shimmers with life; that because of the light being returned to the eye! Did you know that cut affects the value of a diamond by as much as 50%? A well-cut diamond will appear larger than one of similar size that is not as finely cut.

This well-cut beauty from Carizza also doubles as a show-stopper!

emerald cut

Diamonds can be a symbol of love, status and even purity . . . they are also a symbol of strength: A diamond forms under tremendous heat and pressure, just like human character! It takes billions of years to form a diamond, and while humans don’t have that luxury of forever, we grow and learn from life’s challenges. It’s no wonder that people celebrate their special moments with diamonds. Diamonds are also the most durable of gems, and measure 10 on the Mohs scale of mineral hardness.

Star Gems demonstrates that while a diamond may be tough, the right design can be soft and downright feminine.

Ask your American Gem Society jeweler to help you find the perfect diamond. Remember, something as rare and precious as a diamond deserves a report from a well-respected diamond grading laboratory. Ask for one from AGS Laboratories, a nonprofit diamond lab created with the AGS mission of consumer protection and the highest standards of grading.

April is the Month of Brilliance

The birthstone for April is a gem that’s near and dear to us. It’s the keystone of the American Gem Society logo, and they offer grading reports for this precious gem based on science and accuracy. We’re talking about diamonds.

Diamonds have been admired for centuries, and some historians estimate they were traded as early as four BC. One of the reasons it is so admired and valued is because of the process by which a diamond is formed well below the earth’s crust, then forced upward until it is uncovered. These natural forces are what make each and every diamond unique.

Part of the diamond grading process includes testing the diamond for clarity. This is when the lab determines the relative visibility of the inclusions in a diamond and their impact on the overall visual appearance. Inclusions are the internal or external flaws of the diamond which are a result of the tremendous heat and pressure a diamond is subjected to in its journey to the surface.

The gemologists in the AGS Laboratories have come across some very unusual and rare inclusions, which they call “Clarity Rarities.” Click here to see an example of their most recent find!

Diamonds come in several colors, including yellow, red, pink, blue, and green, and range in intensity from faint to vivid. Generally speaking, the more saturated the color, the higher the value.

AGS Laboratories only grades white diamonds and are the leaders in cut grade. Because of their proprietary light performance cut grade, diamond cutters understand how to cut a more beautiful diamond—which means you have more beautiful, sparkling options when shopping for diamonds!

This is why we love diamonds so much. Their beauty is endless and they never cease to amaze us. But enough talk about diamonds, let’s enjoy these gorgeous designs by some of our AGS members!

 

If you’re celebrating a birthday in April, a 60th anniversary (congratulations!), or love diamonds as much as we do, be sure to contact an AGS-certified jeweler near you. They’ll help you find the diamond of your dreams! And don’t forget to ask for an AGS Laboratories Diamond Grading Report. Accept no substitutes, and buy your diamond with confidence!
