The Legacy of Diamond in Jewelry Design
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.
Shop antique and vintage diamond rings, diamond necklaces and other extraordinary diamond jewelry on 1stDibs.
- What is a calibre cut?1 Answer1stDibs ExpertApril 5, 2022A calibre cut is a specific type of cut gemstone used in jewelry. Normally, the term describes jewelry that features multiple small faceted gemstones in square, oval or rectangle shapes arranged closely together to form outlines or accent lines. Find a selection of calibre cut gemstone jewelry on 1stDibs.
- What is an emerald-cut sapphire?1 Answer1stDibs ExpertApril 5, 2022Not to be confused with an emerald gemstone, an emerald-cut sapphire is a sapphire cut into a rectangular shape. An emerald-cut adds the illusion of flashing lights across the stone with its unique shape and step-cut along the edges. Browse a wide selection of sapphire jewelry in a variety of cuts on 1stDibs.
- 1stDibs ExpertOctober 12, 2021The best cuts for a blue sapphire are said to be oval, round, and cushion. The look of an oval-cut sapphire is similar to that of a round sapphire. The slightly extended shape, on the other hand, can make it appear larger than a similar-weight stone. A round cut is one of the most traditional shapes, and it helps a gem dazzle to its full potential. The presence of about 58 facets results in a large amount of light being reflected. Cushion cut, sometimes known as the 'pillow-cut,' has been popular for generations due to its cushion-like appearance. The gemstone has a rectangular form with soft, slightly rounded corners in this cut. Typically, the crown has 58 to 64 big facets. These cuts were popular in numerous forms of jewelry, including rings, pendants, and earrings. Find a wide variety of blue sapphire jewelry on 1stDibs.
