Longines Diamond Watches Vintage

Longines is known for creating some of the most technically innovative and attractive timepieces in the world. Once worn by Humphrey Bogart, Albert Einstein, Richard Byrd and Charles Lindbergh, the company's vintage watches are now sought after by collectors and anyone desiring to wear a high-grade wristwatch.

Antique diamond rings, diamond tiaras and dazzling vintage diamond earrings are on the wish lists of every lover of fine jewelry. And diamonds and diamond jewelry are primarily associated with storybook engagements and red-carpet grand entrances — indeed, this ultra-cherished gemstone has a dramatic history on its hands.

From “A Diamond Is Forever” to “Diamonds Are a Girl’s Best Friend,” pop culture has ingrained in our minds that diamonds are the most desired, the most lasting and the most valuable gemstone. But what makes the diamond so special? Each stone — whether it’s rubies, sapphires or another stone — is unique and important in its own right. April babies might claim diamonds for themselves, but just about everyone wants this kind of sparkle in their lives!

There are several factors that set diamonds apart from other stones, and these points are important to our gem education.

Diamonds are minerals. They are made up of almost entirely of carbon (carbon comprises 99.95 percent; the remainder consists of various trace elements). Diamonds are the hardest gemstones, ranking number 10 on the Mohs Hardness Scale. Even its name, diamond, is rooted in the Greek adamas, or unconquerable. The only object that can scratch a diamond is another diamond. Diamonds are formed deep within the earth at very high temperatures (1,652–2,372 degrees Fahrenheit at depths between 90 and 120 miles beneath the earth’s surface) and are carried up by volcanic activity. Diamonds are quite rare, according to the Gemological Institute of America, and only 30 percent of all the diamonds mined in the world are gem quality.

In the 1950s, the Gemological Institute of America developed the 4Cs grading system to classify diamonds: clarity, color, cut and carat weight. Not all diamonds are created equal (there are diamonds, and then there are diamonds). The value of the diamond depends on the clarity (flawless diamonds are very rare but a diamond's value decreases if there are many blemishes or inclusions), color (the less color the higher the grade), cut (how the diamond’s facets catch the light, certain cuts of diamonds show off the stone better than others) and carat weight (the bigger, the better).

When you start shopping for a diamond engagement ring, always prioritize the cut, which plays the largest role in the diamond's beauty (taking the time to clean your diamond ring at least every six months or so plays a role in maintaining said beauty). And on 1stDibs, a range of buying guides can be found for those in the market for antique engagement rings, vintage engagement rings or Art Deco engagement rings.

Antique, vintage and luxury wristwatches have captured the hearts and minds of all manner of watch collectors as well as the watchmakers themselves — it's time you found your own.

Certain vintage watches for men and iconic watch designs for women are sought after not only because of their graceful proportions or innovative materials but also because of the illustrious histories of the houses that created them, histories that they stylishly embody.

Bulgari’s legendary Serpenti watch was on everyone’s list after the collection’s bold bracelet, which technically debuted after the timepiece, graced the wrist of actress Elizabeth Taylor. If anything, elaborately crafted timepieces — the unmistakably boxy silhouette of Cartier Tank watches, the elegant and minimal Calatrava designed by legendary Swiss house Patek Philippe — are even more effective than the shape we associate with traditional wristwatches.

Form watches — the all-encompassing moniker bestowed upon non-round watches — are making headlines and completing contemporary fashionable ensembles the world over. At the same time, both casual fans and careful collectors are drawn to the unbeatable charm of vintage styles, such as the icons designed by Omega that even James Bond can’t resist.

In the early days of watchmaking, watches were fragile enough that they necessitated protection from the elements. Now, wristwatches made of gold and steel can withstand the harshest climates — even 100 meters underwater, in the case of Rolex’s Submariner. Designer Gérald Genta, whose range of clients included Rolex, created for Audemars Piguet the first luxury sports timepiece to be made from stainless steel. First introduced in 1972, the Royal Oak was a perfect choice for blending the form and function that are now synonymous with sports watches.

Are you shopping for a wristwatch? It’s good to keep your needs as well as your specific personal style in mind: A smaller, subtle timepiece is a good fit for small wrists. When will you be wearing your new accessory? There’s a versatile model out there for everyday wear, while a rugged, feature-heavy watch is a safe bet if you’re prone to embarking on all-weather activities in the great outdoors.
