Diamonds: The 4Cs

A fine diamond is like a smoldering fire trapped in ice. The enigma of its beauty has been a source of fascination for
thousands of years. Its hardness and polish are unsurpassed. Its unique combination of icy brilliance and fiery sparkle is
without peer. No wonder it is used as the supreme expression of love. This crash course in diamond buying will help you
understand how quality diamonds are valued and priced — and help you decide what’s most important to you in a diamond.
The easiest way to explain diamonds is using the four Cs: cut, color, clarity, and carat.

Of all the 4 Cs, cut has the greatest effect on a diamond’s beauty. In determining the quality of the cut, the grader evaluates
the cutter’s skill in the fashioning of the diamond; technology assesses the diamond’s light performance. The more precise the
cut, the more captivating the diamond is to the eye.

Gem-quality diamonds occur in many hues. In the range from colorless to light yellow or light brown, diamonds are
compared to Master Color-Comparison Diamonds under controlled conditions. Colorless diamonds are the rarest. Other natural
colors are known as fancy – their color grading is unique.

Diamonds can have internal characteristics known as inclusions or external characteristics known as blemishes.
When grading clarity, the diamond grading professional uses magnification and specific lighting and considers the effect
these characteristics have on the diamonds appearance and/or durability. Diamonds without inclusions or blemishes
are rare; however, most characteristics can only be seen with magnification.

The carat is the diamond’s physical weight measured in metric carats. One carat equals 1/5 gram and is subdivided
into 100 points. Carat weight is the most objective of the 4 Cs. It involves no estimates, comparisons or judgments.

The Fifth C: Confidence.
When you shop smart — with an American Gem Society’s top jewelers — you will feel confident
in your decision. You know that the jeweler is qualified to describe the characteristics of your diamond, so you could
make the choice that is right for you.







Gem of the Month:

Legends claim that birthstones confer health and happiness to the wearer. Whether fact or fiction,
birthstones are certainly beautiful in their own right. Here they are, listed by month:

January: Garnet
Transparent to semi-translucent, the garnet comes in almost every color,
but reddish orange to purplish red are the most popular. In the 13th century, garnets were
worn to repel insects and evil spirits and to ward off the evil eye of others.

February: Amethyst
A member of the quartz family, the amethyst is usually bluish purple
in color and ranges from very light to very dark. The stone’s availability and purported magical qualities
made it the stone of preference for both commoners and kings 4,000 years ago.

March: Aquamarine
In the beryl family, the aquamarine is greenish blue in tones light to dark.
It was the stone of sea goddesses of past times. Beads of aquamarine were found in ancient mummy tombs.
They were used as tribute to the gods of the netherworld for safe passage.

April: Diamond
The hardest, the most popular, and the most valuable gemstone (up to a certain size),
diamonds come in all colors. Called “The Philosopher’s Stone,” the diamond is an ancient symbol of
the perfected man whose divine spirit shines forth.

May: Emerald
In the beryl family, the emerald is light to dark green, transparent to opaque. In ancient Egypt,
the green gem was highly prized by the wealthy and the priesthood. The high cost made it far beyond
the average Egyptian’s pocketbook, though.

June: Alexandrite or Pearl
By tradition, alexandrite is June’s birthstone, but the stone is very scarce.
Today, most people claim the pearl as June’s birthstone. Ironically, the pearl is not a true gemstone
at all, but comes from oysters.

July: Ruby
Transparent to opaque, the ruby is in the corundum family and is dark red. This stone was given
as offering to Buddha in China and Krishna in India. A common belief was that dreaming of rubies meant
the coming of success in business, money matters, and love.

August: Peridot
Yellow green to lime green, the peridot is often found in Arizona. The ancient Egyptians
made small drinking vessels from peridot. These vessels were used in rituals, and the priests would
drink soma from them. This put them in touch with Isis, the nature goddess.

September: Sapphire
In the corundum family, the sapphire comes in all colors, with blue the most popular.
Clear sapphires are considered guardians of love. In the old days, it was thought to promote chastity in
virgins and ensure fidelity in marriage.

October: Opal
Every color of the rainbow, the opal can be milk white to intensely, vividly varied, depending
on quality. Ancient Arabs believed that opals fell from heaven in flashes of lightning, and that’s how they
received their intense, fiery color.

November: Topaz
Almost always transparent, the topaz comes in many colors, with yellow, gold and blue
the most popular. In the past, it was thought that the wearer of topaz had the magical ability to become invisible.

December: Blue Zircon or Tanzanite
Transparent as a gemstone, the blue zircon was said to be of the same
color as the blue hyacinth flower. Tanzanite, a rare stone mined only in Africa is also considered to be
the birthstone of December.
