Birthstones: The History & Significance

Each month we are featuring the birthstone of the month and did a post listing each of the birthstones & anniversary gemstones.  Most everyone knows their birthstone, but do you know the history and significance of birthstones?

Through out history, gemstones have played a very important role in the lives of people.  In current times birthstones represent the birth month of individuals.  Many believe that birthstones have special powers to those who wear them, others just like wearing a gem that represents the month in which they were born.

When did gemstones first become associated with the months of the year you ask?   Historians believe that the first known records come from the book of Exodus in the Old Testament of the Bible where it is written that  the Hebrew’s high priest is described as having a breastplate with 12 very specific stones mounted in four rows , one for each of Israel’s tribes.   In the first row there was a ruby, topaz and a beryl, in the second row there was a turquoise, sapphire and an emerald, in the third row there was jacinth, agate and an amethyst, and in the fourth and last row there was a chrysolite, onyx and a jasper.  They were all mounted in gold filigree settings , one for each of the names of the sons of Israel, each engraved with the name of one of the twelve tribes.  (Exodus,Chapter 39:9-14, New International Version)

In the 8th and 9th centuries, gemstones were also believed to be connected to the 12 apostles.  Since that time the 12 gemstones have been related to zodiac signs and birth months.  It is believed that the actual wearing of birthstones more than likely originated in Poland around the 15th and 16th century.  Some believed that the powers of a gemstone for a particular month were heightened by the wearer.  For this reason, it is believed that people wore the different birthstones for each month hoping to achieve the full effects of that particular stone.

In 1912 the Jewelers of America organized an official list that would connect each month with a particular stone.  The list changed according to what was most commercially available and not necessarily to what was deemed the proper birthstone for that particular month.  This list is still used today to identify the stone that represents the month.  There are some older birthstones lists that do vary from today’s modern list.

When choosing a birthstone for purchase, keep in mind that the same four C`s that apply to diamond buying also apply to colored gemstone purchases.  Birthstone gems are graded and priced based on the four C’s of Carat Weight, Cut, Color and Clarity as well as place of origin, availability or rarity, possible treatment and of course, the current fashion.  It is not uncommon for a particular birthstone to suddenly rise in price  because it is currently fashionable to wear it.  The type of gemstone a person selects will dictate the care that they require.  For instance, some genuine stones are very durable, while others require more care.  Rubies and sapphires are considered choices for everyday wear while an opal or a pearl require gentle handling.  Simply taking the time to understand how to care for your gemstones can lead to years of enjoyment.

Happy Birthday September Babies!

Happy Birthday to everyone born in September!

Your birthstone is the Sapphire, a symbol of trust and loyalty. Most people recognize a sapphire as a blue gemstone.  In ancient times, it was believed that the color of the sky came from the reflection of a giant sapphire that held the earth.  Truth be told… sapphires come in many colors and the earth does not sit on a sapphire.

Carat Weight – The Size of a Diamond

It’s the old quandary. Is bigger better? Size is sought after, naturally; but overall quality counts in the stretch

This balance of size and quality makes up much of the art of a professional gem cutter. It is the cutter’s job to produce a gorgeous diamond while giving the consumer the highest CARATAGE for his or her money.

Caratage means CARAT, the measurement used to weigh a diamond.

The word carat is taken from the perfectly matched carob seeds that people once used in ancient times to balance scales. So uniform in shape and weight are these little seeds that even today’s sophisticated instruments cannot detect more than three one-thousandths of a difference between them.

Don’t confuse it with KARAT, the method of determining the purity of gold.

What’s The Point?
One Carat= 200 milligrams, or 0.2 grams. 142 carats adds up to one ounce. Carats are further divided into points.

What does all this mean, and how does it work?
The price of a diamond will always rise proportionately to the size of the stone. Larger diamond crystals are more rare and have a greater value per carat. So, a one carat diamond of a given color and clarity will be much more valuable than 2 one half carat diamonds of equal quality.

Synthetic Diamonds

Synthetic diamond is diamond produced in a technological process; as opposed to natural diamond, which is created in geological processes. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, denoting the production method, High-Pressure High-Temperature synthesis and Chemical Vapor Deposition, respectively.

Numerous claims of diamond synthesis were documented between 1879 and 1928; most of those attempts were carefully analyzed but none were confirmed. In the 1940s, systematic research began in the United States, Sweden and the Soviet Union to grow diamond using CVD and HPHT processes. The first reproducible synthesis was reported around 1953. Those two processes still dominate the production of synthetic diamond. A third method, known as detonation synthesis, entered the diamond market in the late 1990s. In this process, nanometer-sized diamond grains are created in a detonation of carbon-containing explosives. A fourth method, treating graphite with high-power ultrasound, has been demonstrated in the laboratory, but currently has no commercial application.

The properties of synthetic diamond depend on the details of the manufacturing processes, and can be inferior or superior to those of natural diamond; the hardness, thermal conductivity and electron mobility are superior in some synthetic diamonds (either HPHT or CVD). Consequently, synthetic diamond is widely used in abrasives, in cutting and polishing tools and in heat sinks. Electronic applications of synthetic diamond are being developed, including high-power switches at power stations, high-frequency field-effect transistors and light-emitting diodes. Synthetic diamond detectors of ultraviolet (UV) light or high-energy particles are used at high-energy research facilities and are available commercially. Because of its unique combination of thermal and chemical stability, low thermal expansion and high optical transparency in a wide spectral range, synthetic diamond is becoming the most popular material for optical windows in high-power CO2 lasers and gyrotrons.

Both CVD and HPHT diamonds can be cut into gems and various colors can be produced: clear white, yellow, brown, blue, green and orange. The appearance of synthetic gems on the market created major concerns in the diamond trading business, as a result of which special spectroscopic devices and techniques have been developed to distinguish synthetic and natural diamonds.

The Shape of a Diamond

The classic diamond is, to most people, a round gem of sparkling white brilliance with a kaleidoscope of dazzling facets to entice the eye.  Yes and no. Diamonds are natural crystals of varying size and shape formed in the earth over millions of years. The traditional round brilliant diamond, though the most popular diamond shape of all, is hardly the whole story.

By the diamond cutter’s art these crystals are carved into gems of spectacular and whimsical beauty. A cutter’s skill will produce a diamond of the greatest size with the fewest flaws and the most brilliance.

Round Brilliant

This shape has set the standard for all other diamond shapes, and accounts for more than 75% of diamonds sold today. Its 58-facet cut, divided among its crown (top), girdle (widest part) and pavilion (base), is calibrated through a precise formula to achieve the maximum in fire and brilliance.


Oval

An even, perfectly symmetrical design popular among women with small hands or short fingers. Its elongated shape gives a flattering illusion of length to the hand.


Marquise

An elongated shape with pointed ends inspired by the fetching smile of the Marquise de Pompadour and commissioned by the Sun King, France’s Louis XIV, who wanted a diamond to match it. It is gorgeous when used as a solitaire or when enhanced by smaller diamonds.


Pear

A hybrid cut, combining the best of the oval and the marquise, it is shaped most like a sparkling teardrop. It also belongs to that category of diamond whose design most complements a hand with small or average-length fingers. It is particularly beautiful for pendants or earrings.


Heart

This ultimate symbol of romance is essentially a pear-shaped diamond with a cleft at the top. The skill of the cutter determines the beauty of the cut. Look for a stone with an even shape and a well-defined outline.


Emerald

This is a rectangular shape with cut corners. It is known as a step cut because its concentric broad, flat planes resemble stair steps. Since inclusions and inferior color are more pronounced in this particular cut, take pains to select a stone of superior clarity and color.


Princess

This is a square or rectangular cut with numerous sparkling facets. It is a relatively new cut and often finds its way into solitaire engagement rings. Flattering to a hand with long fingers, it is often embellished with triangular stones at its sides. Because of its design, this cut requires more weight to be directed toward the diamond’s depth in order to maximize brilliance. Depth percentages of 70% to 78% are not uncommon.

Trilliant

This is a spectacular wedge of brittle fire. First developed in Amsterdam, the exact design can vary depending on a particular diamond’s natural characteristics and the cutter’s personal preferences. It may be a traditional triangular shape with pointed corners or a more rounded triangular shape with 25 facets on the crown, 19 facets on the pavilion, and a polished girdle. It is definitely for the adventurous.

Radiant

This square or rectangular cut combines the elegance of the emerald shape diamond with the brilliance of the round, and its 70 facets maximize the effect of its color refraction. Because of its design, this cut requires more weight to be directed toward the diamond’s depth in order to maximize brilliance. Depth percentages of 70% to 78% are not uncommon.

Cushion

An antique style of cut that looks like a cross between an Old Mine Cut (a deep cut with large facets that was common in the late 19th and the early 20th centuries) and a modern oval cut.

The shape of things to come in diamonds has already produced other fanciful and innovative styles such as the flower, cloverleaf, triangle and kite. Nor does it stop there. Some cuts are variations on standard shapes, others spin off the natural crystal formation of the stone, and still others take the idea of shape to revolutionary new heights. Individuality and taste determine the fashion, and the magic of the gem cutter transforms each stone into a unique work of art.

An Iron… How Romantic?!

Birthday, Anniversary, Valentine’s Day, Holidays…   What to buy?  Well a friend that worked in a local store in a small community told me that men would come in at the last minute to buy a gift for their wives and come to the counter with a iron, vacuum, or other home appliance.  She would sarcastically comment, “Nothing more romantic than the gift of work!”  They would think for a split second and in panic ask for help in picking out a more suitable gift for the occasion. Being a small community, the wives would find out and stop by the store to thank her for helping their husband pick out the perfect gift.
