13 Ct Eternity Band

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.

If you’re shopping for antique and vintage band rings, you likely know that this particular kind of ring is among the most versatile in jewelry.

You don’t need a special occasion to dazzle friends with a flashy sapphire band ring or to make a statement with a wide band ring — this accessory knows no boundaries, and many different iterations have materialized over the years. Whether you’re seeking an unadorned modern sterling-silver band ring for everyday wear or dual gold wedding bands for the big day, there are lots of options waiting for you.

On 1stDibs, there are enduring antique wedding bands to be found dating from the Victorian and Edwardian eras. Jewelers who were active during the reign of Queen Victoria — specifically, the Romantic period — designed rings with large colorful gemstones and decorative motifs, while the jewelry of the latter era was all about the exquisite diamond, platinum and pearl creations made by such famous names as Cartier and Boucheron. Matching wedding bands, which may reduce the stress of wedding-band shopping if you prefer a traditional route, afford you and your partner the chance to have the engagement ring and wedding bands in the same metal and design.

And because band rings aren’t necessarily relegated to black-tie events, they’ve come a long way, design-wise. David Yurman’s band rings, for example, are well known for their integration of mixed metals, and the celebrated jewelry designer’s powerful silver and gold bracelets, rings, pendants and earrings frequently express his iconic industrial-cable motif.

A simple and chic band ring goes with anything, from the evening gown you’ve chosen for a weekend gala to the jeans and vintage tee you’ve thrown on for a casual lunch with colleagues.
