August’s Trio of Distinctive Gemstones

It’s been a year since spinel was added to August’s birthstone line up. Those celebrating a birthday during the eighth calendar month now have three gemstone choices: peridot, sardonyx, and spinel.

Spinel

For those who are still unfamiliar with spinel, it is often assumed to be other gemstones, like ruby or sapphire.  Cobalt blue, like the one above, is one of the most desired colors. But it can be found in a variety of colors, such as the much coveted red, as well as black, violet blue, greenish blue, grayish, pale pink, mauve, yellow or brown. Spinel can also be found in various cuts, like octagons, trillions, squares, rounds and fancy shapes, like ovals, pears, and cushions.

No matter what the shape, spinel is spectacular! Take a look at these designs by our AGS members. Click on the images for a closer view.

 

Peridot

The verdant peridot is the gemstone most commonly associated with August. Peridot’s recognizable green hue could sometimes vary from yellowish-green to olive to brownish green, contingent on how much iron is present. Yet the finest peridot is a brilliant green without any hints of brown or yellow.

Sardonyx

Sardonyx

Since as far back as Roman times, sardonyx has been highly valued as a stone representing strength, courage, happiness, and clear communication.

The unique reddish, zebra-striped banding of sardonyx stands out beautifully when the stone is smoothed, so it is often cut in cabochon and worn as beads or featured in an eye-catching pendant or ring.

Sardonyx makes a great gift for those born in August who want something a little different than the traditional birthstone. Readily available and relatively inexpensive, sardonyx makes an affordable addition to anyone’s collection.

Four Fun Facts About January’s Gemstone

Rhodolite garnet and emerald sunbeam earrings by Ricardo Basta Fine Jewelry.

If you’re celebrating a birthday or any special occasion this month, then the garnet is a worthy addition to your fine jewelry wardrobe. Here are four fun facts about the colorific January gem:

1. Not all garnets are red.

Garnet is actually the name of a group of minerals that comes in a rainbow of colors, from the deep red of the Pyrope garnet to the vibrant green of Tsavorites. Some rare garnets are even blue, colorless, or—most rare of all—change colors in different lights. But the most common color is a beautiful range of reds, from rust colored to deep violet-red.

2. It’s more than just a gemstone.

For thousands of years, the garnet has lived a glamorous life as a gemstone. But in the past 150 years, it has also been put to the test as an effective industrial mineral. In the United States, garnet has been utilized for waterjet cutting, abrasive blasting, and filtration.

3. Their inclusions make them unique.

Some garnets have inclusions that are part of the beauty of the overall stone (like “horsetails” in Demantoid garnets, or Hessonite garnets which sometimes have a “turbulent” look). So you may discover that you like the distinctive look these inclusions bring to the piece.

4. Garnets have been around for a very long time.

The garnet is so durable, remnants of garnet jewelry can be found as far back as the Bronze Age. Other references go back to 3100 BC when the Egyptians used garnet as inlays in their jewelry and carvings. The Egyptians even said it was the symbol of life. The garnet was very popular with the Romans in the 3rd and 4th Century.

Today, the garnet can be found in a range of jewelry pieces and styles, from beautiful rings to stunning tiaras. Since the garnet can come in a range of colors, rare garnets in green or blue make breathtaking pieces, especially in pendants or drop earrings.

Here are a few designs from AGS members featuring the many colors of the garnet. Click on the images for a larger view.

The Mistaken Identity of November’s Birthstones

novemberbirthstonesThe month of November is represented by two richly colored gemstones: topaz and citrine. The gemstones look similar, in fact, that they’ve often been mistaken for one another throughout history. But they are actually unrelated minerals, and topaz occurs in a wide variety of colors far beyond yellow.

The good news is that both of these gemstones are fairly abundant and affordably priced, which means anyone can find a topaz or citrine that will fit their budget.

Topaz

Once upon a time, all gems that were yellow were once considered topaz, and all topaz were presumed to be yellow. Alas, it’s been discovered that topaz is available in a wide variety of colors, with Imperial topaz—a vibrant orange hue with pink undertones— being the most prized. Blue topaz, although abundant in the market, rarely occurs naturally and is often caused by irradiation treatment.

Pure topaz is colorless, but it can become tinted by impurities to take on any color of the rainbow. Precious topaz, ranging in color from brownish orange to yellow, is often mistaken for “smoky quartz” or “citrine quartz,” respectively—although quartz and topaz are unrelated minerals.

Topaz is a traditional gift for those with November birthdays. It’s also given to celebrate 19th wedding anniversaries, and certain types (blue and Imperial, respectively) acknowledge 4th and 23rd wedding anniversaries, as well.

When buying topaz, realize that this gem is most often treated with irradiation to produce desirable colors—particularly blue. Because these processes so closely resemble how topaz forms in nature, there is practically no way to determine whether a stone has been treated.

Citrine

The second birthstone for November, citrine, is the variety of quartz that ranges from pale yellow to brownish orange in color. It takes its name from the citron fruit because of these lemon-inspired shades.

The name “citrine” was commonly used to refer to yellow gems as early as 1385 when the word was first recorded in English. However, since the gem’s color closely resembled topaz, the two November birthstones shared a history of mistaken identities.

Once citrine was distinguished from topaz, it quickly became popular in women’s jewelry as well as men’s cufflinks and rings. Today, it remains one of the most affordable and frequently purchased yellow gemstones.

Whether shopping for a November birthday, a 13th wedding anniversary, or just an affordable piece of jewelry to complement any style, citrine makes a perfect gift. These beautiful design from AGS members ought to spark some gift ideas. Be sure to click on the images to get a larger view.
