DIAMOND

April Birthstone

Since ancient times, diamonds have been admired objects of desire. Formed one hundred miles beneath the Earth’s surface over a billion years ago, diamonds are the hardest gem of all. Diamonds have a long history of folklore; some of which say diamonds were created when bolts of lightning struck rocks, and others said the gem possessed healing powers. For centuries, diamonds have been adorned by women and men and regarded as the ultimate gift and a symbol of eternal love.

Today, diamonds are still admired all around the world. Until the middle of the twentieth century, there was no standard by which diamonds could be evaluated. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4C’s of Diamond Quality are the universal method for assessing the quality of any diamond, anywhere in the world.

Ancient Egyptian mummies were often buried with an Emerald carved with the symbol of verdure– flourishing greenness–on their necks to symbolize eternal youth.

Fancy Colored Diamond Jewelry

FANCY COLOR DIAMONDS

Fancy color diamonds are true miracles of nature. The geological conditions needed to create these colors are rare, making them scarce and highly prized. They come in pale pinks and blues, bright yellows, oranges, greens, reds, and brown colors like cognac and champagne.

Fancy-color diamonds are evaluated by their color intensity, unlike colorless diamonds that are graded on their fire and brilliance. Shades that are deep and distinct in color are rated higher than light or pale shades. GIA describes color in terms of hue, tone and saturation. Hue refers to the diamond’s color, tone refers to the color’s lightness or darkness, and saturation refers the color’s depth. Using highly controlled viewing conditions and color comparisons, a fancy color grader selects one of 27 hues, then describes tone and saturation with terms such as “Fancy Light,” “Fancy Intense,” and “Fancy Vivid.” This color system was developed by GIA and is used worldwide.

Today, yellow diamonds are thought of as “traditional” and are among the most abundant of all “fancy colored” diamonds. Red, green, purple, and orange diamonds are generally the rarest, followed by blue and pink.

PEARLS

June Birthstone

In all of human history, mankind has admired, even worshipped, pearls. Persian mythology called them “the tears of the gods.” Ancient Chinese legend claims the moon holds the power to create pearls, instilling them with its celestial glow and mystery.

Pearls are unique because they are the only gemstone formed within a living creature. Since natural pearls are rare and difficult to recover from the ocean’s depths, man invented the technique of culturing salt and freshwater pearls from mollusks carefully seeded with irritants similar to those produced by nature.

Cultured pearls come in many beautiful colors, from pale cream and white to rose, lilac, green, gold, gray, and black. There are four main types of cultured pearls: Akoya, South Sea, Tahitian, and Freshwater each having unique qualities that separates them for the other.

Today pearls are both classic and contemporary; a strand of white pearls can be timeless but a bracelet of chocolate pearls is more modern. One thing to keep in mind with pearls, no matter the color or size, they can be worn every day or they can compliment the most formal attire.
