Mappin Webb Antique Diamond

Appointed the Crown Jeweler in 2012, Mappin & Webb is one of the most widely recognized makers of silver and luxury goods in the world. With a roster of prestigious clients that has included six British monarchs as well as Charles Dickens, Winston Churchill and Harry Houdini, the historic firm has supplied fine jewelry and silver objects for royalty all over the globe including the Russian Imperial Household, the Siamese royal family and the Indian Maharaja.

Mappin & Webb’s origins are rooted in Jonathan Mappin’s workshop in Sheffield. He opened in 1775 with the intent to serve British society with the highest quality silverware ever made. His son and grandson, both named Joseph, carried on his vision until the mid-19th century when his four great-grandsons incorporated the business into Mappin Brothers Ltd. and embarked on a substantial expansion of the firm.

Nearing 1860, two of the great-grandsons, eldest Sir William Mappin and youngest John Mappin, left to pursue other opportunities. John opened his own business, Mappin & Company, and was joined two years later by his brother-in-law George Webb. Webb passed away in 1868 — the same year that saw the family form Mappin & Webb Co.

Webb’s name lived on in the company even after 1889 when the company became Mappin & Webb Ltd. In 1897, Mappin & Webb were granted their first Royal Warrant as silversmiths to Queen Victoria. The firm has been a holder of Royal Warrants since then.

Mappin & Webb supplied soldiers in the battle of Omdurman with their acclaimed Campaign watch. The company also supported wartime efforts during both World Wars in their enormous factory in Sheffield. Today Mappin & Webb is among the most prominent makers of Sheffield silver in the world.

Watches of Switzerland Operations Ltd. acquired Mappin & Webb in 1998 after a series of mergers and acquisitions.

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.
