May’s Birthstone – Emerald – Green Beryl

In a set of poems released by Tiffany & Co. in 1870, each month is matched with a gemstone. The poem for May reads:

Emerald Ring 14 Karat White Gold Heart Shape 4.7 Carats R61618

Emerald Ring 14 Karat White Gold Heart Shape 4.7 Carats R61618

“Who first beholds the light of day
In spring’s sweet flowery month of May
And wears an emerald all her life
Shall be a loved and happy wife.”

Emerald is a rich forest green color gemstone. It is a member of the Beryl mineral family along with siblings Aquamarine and Morganite. Emerald is also a member of the four precious gemstones along with Ruby, Sapphire and Diamond.

Emerald‘s chemical composition includes the elements Beryllium (Be), Aluminum (Al), Silicon (Si) and Oxygen (O). The dark green color of Emerald is created by trace element Chromium (Cr), and sometimes Vanadium (V). Green Beryl is only considered an Emerald if it has a strong green to dark green color. The lighter green Beryls are simply called “Green Beryl.” This is very similar to Ruby Vs. Pink Sapphire and Rubellite Vs. Pink Tourmaline.

Emerald (and other beryls) are quite hard at about 7.5 to 8 on the Mohs scale. The emerald is often clouded by inclusions. They are not classified as faults but show the difference between natural and synthetic stone. Almost all natural emeralds are treated with oil to fill in and diminish the appearance of these inclusions and fissures. Due to these inclusions and fissures, emeralds can be rather brittle or fragile. A little extra care is needed when using emeralds in jewelry.

Unlike Diamonds, Emeralds’ clarity is judged by the naked unaided eye because of these inherent inclusions. Diamonds are generally judged with a 10x loupe for their clarity.

Columbia is currently the largest producer of fine Emerald gemstones. Brazil and Zambia are also very large producers of fine Emeralds. Brazilian emeralds are prized for their excellent clarity and slightly yellowish green color, while Zambian emeralds are desired for their slightly bluish green color, which is similar to that of Colombia’s ’emerald-green’ emeralds.

The Gachala Emerald is one of the largest gem emeralds in the world, at 858 carats (171.6 g). This stone was found in 1967 at La Vega de San Juan mine in Gachalá, Colombia. It is housed at the National Museum of Natural History of the Smithsonian Institution in Washington, D.C. One of the world’s largest emeralds is the so-called ‘Mogul Emerald’. It dates from 1695, weighs 217.80 carats, and is some 10cm tall. One side of it is inscribed with prayer texts, and there are magnificent floral engravings on the other side. This legendary emerald was auctioned by Christie’s of London to an unidentified buyer for 2.2 million dollars on September 28th, 2001.The New York Museum of Natural History, exhibits a cup made of pure emerald, which belonged to the Emperor Jehangir, next to the ‘Patricia’, one of the largest Colombian emerald crystals, which weighs 632 carats.The Viennese treasury contains a vase, 4.5 inches (12 cm) high, with a weight of 2205 carats, which was cut from a single emerald crystal.

Both hydrothermal and flux-growth synthetics have been produced, and a method has been developed for producing an emerald overgrowth on colorless beryl. Hydrothermal synthetic emeralds have been attributed to IG Farben, Nacken, Tairus, and others. The first satisfactory commercial product appeared on the market in the 1960s. These stones were initially sold under the names “Emerita” and “Symeralds”, and they were grown as a thin layer of emerald on top of natural colorless beryl stones.The largest producer of hydrothermal emeralds today is Tairus in Russia, which has succeeded in synthesizing emeralds with chemical composition similar to emeralds in alkaline deposits in Colombia, and whose products are thus known as “Colombian Created Emeralds” or “Tairus Created Emeralds”.

Emerald is thought to bring good luck and enhance well-being. The magnificent green of the emerald is a color which conveys harmony, love of nature, life and of the springtime. It has also, for centuries, been the color of beauty and of constant love. In ancient Rome, green was the color of Venus, the goddess of beauty and love. Today, this color still occupies a special position in many cultures and religions. Emerald is also thought to be a stone of wisdom, enhancing memory and increasing mental clarity. Emerald is the anniversary gemstone for commemorating the 20th and 35th year of marriage.

New Gemstone Line and Men’s Cobalt and Ceramic Rings

We have been working on a brand new line of large gemstone sterling silver pendants, earrings and rings for a few months now. We finally have the first set of new designs available. We are still working on many more new designs to add to this line.

We have a new line of men’s cobalt and ceramic band rings. There are some cool new titanium rings on the way soon, too.

In the works, we have a whole new line of amber sterling silver jewelry.

Here are some of the new pieces:

What is a carat? Carat Weight and Millimeter Dimensions of a Gemstone Explained

We get quite a few inquiries from customers asking why the same millimeter size of gemstone has different carat weights from one gemstone to another. We also get customers saying he/she expected the gemstone to be larger/smaller because of the carat weight listed. We thought we should take a few minutes to explain why this is.

Aquamarine Gemstone Earrings - Peora JewelryCarat is a unit of measurement. It is used to measure mass or weight. You might think of diamonds when you hear the word “carat,” but it is actually used to measure all types of gemstones in jewelry.

A carat is exactly 200 milligrams or 0.2 grams. When referring to diamonds, most jewelers will use the term “point” or “pointer” to describe the size of a specimen. As you may have guessed, a “point” is 0.01 carat or 1/100th of a carat. So a ten “pointer” diamond would be 1/10th of a carat or 0.1 carat.

Now, when we try to equate carat weight to physical dimensions like millimeters, things get a bit tricky. Because diamonds and gemstones come in all sorts of shapes, each shape will convert differently between carats and millimeter size. With diamonds, it is generally accepted that a 1.00 carat round diamond will be 6.5 mm in diameter, but a 1.00 carat princess or square shape diamond will be 5.5 mm in diameter.

Emerald Gemstone Pendant Necklace - Peora JewelryDiamonds are more or less the standard comparison for carat weight and millimeter size. However, depending on the type of gemstone, the carats to millimeter difference can vary widely. Each gemstone or mineral type has a different density, which means it will convert from carats to millimeters differently.

Let’s take the diamond’s most commonly used inexpensive stand-in, Cubic Zirconia, as an example. The Cubic Zirconia is actually much denser than diamond, roughly 1.7 times as dense. So a 1.00 carat round CZ would actually be only a 5.3 mm diameter compared to the 6.5 mm of a diamond with the same carat weight. Some other gemstones that are more dense than diamonds include: sapphire, ruby, alexandrite and garnet.

Garnet Gemstone Ring - Peora JewelryConversely, let’s take Opal as another example. Opal is significantly less dense than diamond so it will be a much larger size stone with the same carat weight. A 1.00 carat round Opal will be almost 8 mm in diameter compared to the 6.5 mm 1.00 carat diamond. Other gemstones that are less dense than diamonds include: amethyst, tourmaline, aquamarine, emerald and quartz. Topaz and Peridot are fairly close in density to diamond.

So what do we take away from all of this? Basically, if you are searching online for a piece of gemstone jewelry that is not a diamond, you might as well disregard the carat weight altogether. Just look for the millimeter dimensions of the gem and pull out your trusty ruler.
