Untreated Ruby Bracelet

This deep red gem is the color of heat and passion — vintage and antique ruby jewelry is perfect for those born in the middle of summer.

Rubies are one of the few gemstones that can give diamonds a run for their money. Just consider the Van Cleef & Arpels “scarf” necklace the Duke of Windsor presented to the Duchess on her 40th birthday, in 1936 — set with diamonds and dripping with rubies, a testament to the deep-red gemstone’s power — or the slippers encrusted with 4,600 rubies that Harry Winston made to commemorate The Wizard of Oz’s golden anniversary. July babies have permission to adorn themselves with this beautiful red stone even when it’s not their birthday.

Rubies are considered precious stones — along with diamonds, sapphires and emeralds — and have a hardness of 9.0 on the Mohs Scale, surpassed only by Moissanite and diamonds. They are composed of corundum, a colorless mineral that is also the basic material of sapphires. In the July birthstone, the red of the gemstone — and the various hues seen in sapphires — are produced by the presence of trace elements. In the case of a ruby, this element is chromium. Rubies range in color from vermilion to a violet red. They are also pleochroic, which means that a stone’s hue can vary depending on the direction of viewing. The most sought-after color is pigeon’s blood: pure red with a hint of blue.

Rubies that are hosted in dolomite marble are the most prized: Because the marble is low in iron, so are the rubies, resulting in a more intense color. Rubies found in basalt, which has a higher iron content, are generally darker and less intense.

When shopping for antique and vintage ruby jewelry, remember that the 4Cs of selecting the perfect diamond — color, clarity, cut and carat — also apply to rubies.

According to the Gemological Institute of America, the color of the July birthstone should be a vibrant to slightly purplish red, and the stone should be clear and inclusion-free. Accordingly, the cut should show off its color and clarity. As for the last criterion, fine rubies more than a carat in weight are rare. Often, large rubies are more expensive than diamonds of comparable weights.

Today, antique and vintage bracelets are versatile and universally loved accessories that can add polish and pizzazz to any ensemble.

Bracelets were among the jewels discovered to have been buried with Pharaoh Tutankhamun when his tomb was unearthed in 1922, and wrist and arm bracelets were allegedly worn by Queen Puabi in Sumer, southern Mesopotamia. But preceding the adornments of Ancient Egypt and elsewhere, the people of prehistoric times likely wore the decorative accessory, fashioning it from shells and fish bones. When the Bronze Age allowed for more durable materials and semiprecious stones to be incorporated into jewelry, bracelets became a treasured symbol of wealth.

In the thousands of years following the debut of the world’s first bracelets, the artistry behind this common accessory has only broadened, with designers at popular jewelry houses growing more venturesome over time. David Webb looked to nature for his Animal Kingdom bracelets, and for her best-selling bracelets and more at Tiffany & Co., Elsa Peretti would frequently do the same. From bangles to tennis bracelets, the modern age offers plenty of options.

Internationally acclaimed bracelet designs have on occasion become powerful symbols of status, style and, in the case of Cartier's iconic design, love. The Cartier Love bracelet can be found on the wish list of most jewelry lovers and on the wrist of some of the world’s biggest stars. Its arrangement of mock screwheads and distinctive functionality — it was initially locked and unlocked with an accompanying vermeil screwdriver — is an enduring expression of loyalty, unity and romance. (Do you know how to spot a fake Cartier Love bracelet?)

While the Love bracelet has played a role in the skyrocketing popularity of cuff-style bracelets, they are far from the only glamorous option for collectors. Make a statement with an Art Deco design, a style that sees all kinds of iterations fitted with studded cuffs, one-of-a-kind shapes and dazzling insets. A chunky vintage gold bracelet in the Retro style will prove eye-catching and elevate any outfit.

One of the best things about bracelets, however, is that you never have to choose just one. Style icon Jacqueline Kennedy stacked her Croisillon bracelets — designed by Jean Schlumberger for Tiffany & Co. — with such frequency that the ornate bangles were eventually dubbed “Jackie bracelets” by reporters. Contemporary silver pieces can easily complement each other, rendering a layering of luxury almost a necessity.
