Marie Antoinette Earrings

Marie Antoinette Earrings

There’s no more fascinating subject in history than the doomed French Queen Marie Antoinette. Much maligned by history (she never said “Let them eat cake,” in response to the people’s need for bread), she was an unwilling part of the one of the greatest revolutions in history. And met an untimely end at the guillotine in 1793. While she loved jewelry, and possessed many magnificent jewels, she often preferred simple muslin gowns and very little jewelry. Many of the portraits of her by Elisabeth Vigee-Lebrun show her dressed just like that.

Two large, pear-shaped diamond earrings, weighing 14.25 and 20.34 carats respectively, are part of the Smithsonian Institution’s collection. The diamonds once were supposedly set in earrings that belonged to Marie Antoinette and some sources say they were her favorite pieces of jewelry and she wore them constantly. They were taken from her during an attempt to flee France as the Revolution dawned and the position of the Royals became dangerous.

The diamonds were later acquired by the Grand Duchess Tatiana Yousupoff of Russia. When jeweler Pierre Cartier puchased the diamond earrings in 1928, their authenticity was attested to in an affidavit by Russian Princess Zenaide Yousupoff and her son, Prince Felix Yousupoff, stating that they originally belonged to Queen Marie-Antoinette and have never been reset in the one hundred years that they were in the family. Marjorie Merriweather Post acquired the earrings from Pierre Cartier in October 1928. Harry Winston reset the large diamonds in platinum replicas of the original silver settings in 1959. Cartier, Inc. designed the triangular tops. In November 1964, Mrs. Post's daughter, Mrs. Eleanor Barzin, donated the earrings, along with the original setting to the Smithsonian Institution. The diamonds are originally from India or Brazil, the only significant sources of diamonds in the eighteenth century.

Blue Heart Diamond

blue heart diamond ring
There is a spectacular diamond in the Smithsonian Collection called the Blue Heart Diamond. Fans of the movie Titanic might think the “Heart of the Ocean Diamond” was based on this stone, and it may have been! However, this diamond hasn’t been cast in the ocean, but is safe and sound at the Smithsonian!

It has also been called the Eugenie Blue Diamond, although it’s uncertain that the Empress Eugenie ever owned this particular stone. It was cut in Paris between 1909 and 1910, but the stone’s origin – Africa or India – is unclear.

It is an enormous heart-shaped, blue diamond weighing 30.82 carats. Its current setting is in a platinum ring, surrounded by white diamonds. It changed hands among famous jewelers – such as Cartier and Van Cleef & Arpels - and owners until it was bought by Harry Winston in 1959 who mounted the diamond in its current ring setting. Winston sold the ring to Marjorie Merriweather Post. Mrs. Post donated the ring to the Smithsonian and it remains there with other famous blue diamonds, including the Hope Diamond and the Heart of Eternity Diamond.

These famous blue diamonds have recently gone through a grading and examination process, to classify their colors and to determine the source of the color. The Hope Diamond is classified as Fancy Deep Grayish-Blue. The Heart of Eternity has been classified as a Fancy Vivid Blue. The Blue Heart Diamond has not yet been classified, but some experts categorize it as either Fancy Vivid Blue or Fancy Deep Blue. Blue diamonds are of particular interest to scientists not only because of the color and the impurities that create it, but because blue diamonds also have an electric conductive property that makes them unique among clear and other colored diamonds.

Minerals are Crystals

The earliest forms of jewelry were items that early humans found naturally, such as shells orbits of bones. Early grave sites have also revealed that pre-historic man buried his dead with flowers and with carved ivory beads. These primitive beads would have taken at least an hour each to make.

Early man also might have found bits of turquoise that occurred naturally in areas of Turkey and North America. The pearlescent swirls found inside an abalone or conch would have also been used as jewelry.

They might have also found the earliest types of precious gems in the form of natural crystals, such as quartz or diamonds. Crystals are solid substances where the molecules are arranged in a symmetrical fashion, and they generally fall into one of six shapes:

pyriteIsometric, or cubic crystals are shaped like blocks and are symmetrically shaped. An example of an isometric crystal would be pyrite. This is also called fool’s gold because it has a metallic yellow or brassy color similar to gold.

zircon
Tetragonal, where the crystals are shaped like four-sided prisms and pyramids. An example of a tetragonal crystal is the zircon.

aquamarinesHexagonal crystals are shaped like six-sided prisms, or pyramids. An example of this kind of crystal is the beryl, which includes gems like emeralds and aquamarines.

Topaz
Orthorhombic crystals. An example of an orthorhombic crystal is topaz. Topaz can come in a variety of colors, although the mostly highly prized is a deep amber color. At one time, topaz was much more valuable, until rich veins of it were found in Brazil, which devalued the market.

gypsumMonoclinic crystals are short and stubby, with tilted faces at each end. Monoclinic crystals include gypsum.

feldspar
Triclinic crystals are usually flat with sharp edges but no right angles. Each crystal has three unequal axes. An example of triclinic crystal is feldspar.

Hope Diamond Is A Curse?

hope diamondIs there anyone who hasn’t at least heard of the famous Hope Diamond? Many people are surprised when they first learn that this famous stone isn’t a clear diamond, but instead is a brilliant blue stone, surrounded by white diamonds and suspended from a diamond necklace.


Hope Diamond in a NecklaceIt first appears in history in the mid 1600s when it was purchased by a merchant named Jean Baptiste Tavernier, who sold the stone to Louis XIV of France. At that time it was a 112-carat stone, described as having a beautiful violet color. It was recut into a 67-carat stone and the color was named French Blue. During the French Revolution, the diamond was stolen during a looting of the crown jewels. It reappeared in 1812, but recut once again and was acquired by George IV of England who had to sell the stone to pay off debts. The exact transaction is unknown, but the diamond is next found as an entry in the collection of Henry Philip Hope, whose name is attached to the diamond to this day.

Hope Diamond a curse?
Eventually the stone was owned by the Cartier jewelry firm in Paris and purchased by Evalyn Walsh Maclean of Washington, DC. It was at her request that the stone was reset and made into the necklace that we know of today. It was acquired by Henry Winston who purchased it from Mrs. Maclean’s estate in 1947 and eventually became part of the Smithsonian Collection.



McLean wearing the Hope DiamondThere is a long-standing legend of a curse attached to the Hope Diamond, which the story says was plucked from an idol in India. True or not, many who have owned the Hope Diamond have met with misfortune, including the Hope family, who supposedly went bankrupt from owning the diamond. It’s possible that the whole concept of the curse originated with Pierre Cartier who sold it to Mrs. Maclean with the story of a curse, because she thought objects surrounded with bad luck were actually good luck for her. Sadly, Mrs. Maclean’s first son was killed at age 9 in a car accident and her 25-year old daughter committed suicide. Her husband was declared insane and was institutionalized until his death in 1941. Was it part of a curse?

Selecting Diamonds

Diamonds are graded for certification by laboratories using grading criteria. Four of these criteria are critical to understand when making a diamond purchase or investment.

Known as the “Four C’s” these criteria are:
color, cut, clarity and carat.

Color is the result of the composition of a diamond and it does not change. When a jeweler is describing the color of a diamond they are referring to the presence or absence of color in white diamonds. Because a diamond with no color allows maximum light to pass through, colorless diamonds are preferred for their sparkle.

Cut refers to a diamonds reflective quality. Most diamonds are cut with 58 facets. The brilliance of diamonds is heavily dependent on the cut. The different angles and the finish of a diamond determine its ability to reflect light and cause its brilliance and fire. Remember that the cut of a diamond can have an impact on its durability as well as its beauty. Some cutting faults can make a diamond prone to breakage. A diamond that is cut too thin can also cause light to leak out of the back and the diamond will lose some of the sparkle and appear not to shine. So, as you can see the Cut is probably the most important of the Four C’s.


Clarity. During the formation process, inner flaws, or inclusions occur in most diamonds. The number and size of these inclusions determine what is referred to as the clarity of a diamond. Diamonds that are clear create more brilliance and therefore are rarer and highly priced. To be considered “flawless”, a diamond must have no surface or internal imperfections visible upon being viewed by a skilled diamond grader using 10 power magnifications.

Carat is the unit of weight by which diamonds are measured. One carat is equal to 200 milligrams. A carat is divided into 100 segments called points. 150 points would equal one and a half carats.

When you go to the store to make that all important diamond purchase, do not be shy! Ask questions, get the answers needed to make an informed purchase. Shopping for certified diamonds enables you to make an informed selection. Knowing the “four C’s” allows you to comparison shop and purchase the best diamond at a fair price. But, before making a purchase, shop around and decide what shapes and styles really appeal to you. Enjoy your diamond for years to come!

Couples Diamond


The smart groom-to-be does his research before buying his fiancĂ©e a diamond ring! There are more styles and cuts to choose from than ever before. It’s not enough to be educated about the four Cs of diamonds – cut, color, clarity and carats. Now there are all types of diamond cuts and settings to choose from.

round brilliant diamond
The most popular style is still the round brilliant. It’s one of the earliest cuts ever developed and now relies on precise mathematical equations to create a stone with fire and brilliance that the earliest gem cutters could only have dreamed of.

princess-cut diamond
But many brides want something completely unique. There are many traditional cuts to choose from. A pear-shaped is just that – wider at one end than the other. Or she can choose an oval, emerald or heart-shaped diamond. There are other cuts with unique faceting, such as the square princess-cut diamond.

Ashoka diamond
Some cuts are patented, like the elongated Ashoka diamond or the Asprey & Garrard Eternal cut diamond. Other branded and patented cuts include:

Asscher cut diamond
Elara – a square-cut diamond with rounded corners
Asscher – a square diamond with rounded facets that gives an unusual complexity to the diamond
Couples diamond – this diamond is faceted to reveal either a circle of hearts or arrows inside. It’s a truly unusual diamond that requires precise cutting for the image to appear properly.

The price of a diamond increases exponentially with its carat weight. A one-carat diamond costs much more than 10 10-point diamonds and a two-carat diamond costs more than twice as much as a one-carat diamond (given equal quality in other areas).

Asprey-cut diamond
One way to enhance a ring is with embellishments such as baguettes or trillions. A baguette is a small emerald-shaped diamond that can be placed on either side of the main stones and a trillion is a triangle-shaped diamond that also is a good enhancement to the center stone.

Portuguese Diamond, Anyone?

There’s something so exciting about these incredibly large and perfect stones. Sometimes they have well-documented histories and we know where they came from and who owned them and when. But others have a past that’s not as well-known, and that only adds to the romance and mystique surrounding them.

One such diamond is called the Portuguese Diamond and is a 127-carat, cushion-cut diamond, shaped in an octagonal emerald shape. It’s nearly flawless. While it’s called the Portuguese Diamond, with a story that it was mined in Brazil and became part of the Portuguese Crown Jewels, there’s really no true documentation that says definitively that that’s where the diamond was mined. Must of the diamond’s history is pure legend and conjecture. One can only imagine who wore this incredible stone!

One part of the diamond's history that is well-documented is that in February 1928 Peggy Hopkins Joyce traded a $350,000 pearl necklace for the diamond and $23,000 in cash. According to New York newspaper accounts, it was mounted on a diamond-studded platinum choker to be worn close around the throat (probably the same necklace described above). Miss Joyce performed in the Ziegfeld Follies, and had six husbands, at least five of whom were wealthy. She was said to be almost as fond of jewels as of men. Sometime prior to 1946 Miss Joyce placed the diamond on consignment to the group of jewelers mentioned above, in an unsuccessful attempt to sell it.

Harry Winston acquired the Portuguese Diamond from Miss Joyce in 1951, and for the next several years it traveled the country as part of his "Court of Jewels" exhibition. In 1957, Winston sold the diamond to an international industrialist, who then traded it back in 1962. In 1963, the Smithsonian acquired the Portuguese Diamond from Mr. Winston in exchange for 2,400 carats of small diamonds.

How to Spot A Fake Diamond

In this world of advanced technology it is almost impossible to simply look at a diamond and determine whether it is real or not – especially if you don’t know much about diamonds. There are some steps that you can take to avoid buying a fake diamond, however.

First, only deal with reputable jewelers, and when you find a reputable jeweler, stick with them. Avoid buying diamonds or other jewelry from jewelers that you have never dealt with before in the past. Ask to see the certificate for the stone. If no certificate exists, walk away.

Look at the setting that the stone is in. Fake diamonds, such as zirconias, are usually set in low quality metals. Take a close look at the stone. Fake diamonds are not durable – natural diamonds, on the other hand, are the most durable stone on the planet. Look for scratches or nicks.

After purchasing a diamond, take it to another jeweler for appraisal. In fact, take it to two or three other jewelers for an appraisal to make sure that the appraisals are all fairly close. If you find that you have purchased a fake diamond, you may be accused of making a switch when you return to the store of your purchase; therefore, it is important to have a certificate for the diamond. No two stones are alike.
