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.
Questions About Marquise Black Diamond
- Are Marquise diamonds good?1 Answer1stDibs ExpertFebruary 17, 2023Whether marquise diamonds are good is largely a matter of personal preference. However, many people appreciate the shape of the cut or feel that it looks flattering on their hands. Also known as the navette cut (meaning “little boat” or “sailboat” in French), marquise-cut stones are easy to identify due to their elliptical shape that is tapered on both ends. Stones with a marquise cut are considered modified brilliant because they have 58 facets. On 1stDibs, find a variety of diamond jewelry from some of the world's top sellers.
- 1stDibs ExpertJune 15, 2023What a marquise diamond symbolizes is largely a matter of individual interpretation. Some people associate the elongated shape with joy and happiness, while others believe it is a symbol of love. On 1stDibs, shop a collection of marquise-cut diamond jewelry on 1stDibs.
- 1stDibs ExpertFebruary 13, 2023Marquise cut diamonds can be less expensive per carat compared to other popular diamond shapes. The 4Cs, the grading system that was established by the Gemological Institute of America (GIA) in the 1950s, are the guidelines that determine how marquise diamonds are graded. The price of marquise cut diamonds will be affected by market conditions as well as the aforementioned 4Cs, which are carat weight, color, clarity, and cut quality. Find a collection of diamond jewelry on 1stDibs.
- 1stDibs ExpertOctober 19, 2021A marquise-cut diamond looks great in a variety of settings, but you should choose one that protects the center stone. Some of the top marquise diamond ring settings are bezel, prong and halo. Find a variety of marquise-cut diamond rings on 1stDibs today.
- Is black diamond a real diamond?1 Answer1stDibs ExpertApril 5, 2022Yes, a black diamond is indeed a real diamond. There are three types of black diamonds; natural, Carbonado and treated black diamonds. Treated black diamonds are altered with high pressure and high heat to achieve the black color. Shop a collection of expertly vetted gems from some of the world’s top sellers on 1stDibs.
- 1stDibs ExpertFebruary 22, 2021Yes, a black diamond is a real diamond. Black diamonds have the same chemical composition as traditional colorless diamonds. Although black diamonds are rarer than colorless diamonds, they are less coveted and therefore cheaper.
- 1stDibs ExpertOctober 12, 2021Black diamonds are said to have a deep spiritual connotation and are frequently used to ward off evil. The gorgeous dark gemstone is thought to offer a link between the spiritual and physical worlds. Diamonds, in general, represent a deep emotional bond, which is why they are ideal for engagement rings. On 1stDibs, find a variety of black diamond jewelry and watches.
- 1stDibs ExpertAugust 26, 2024The difference between a black diamond and a black sapphire is that the two are different gemstones. A black diamond consists of carbon converted to a crystalline solid through changes driven by pressure and temperature. A black sapphire is a type of corundum, an aluminum oxide mineral. Generally, black diamonds are harder, rarer and more expensive than black sapphires. On 1stDibs, shop an assortment of black diamond and sapphire jewelry.
- 1stDibs ExpertSeptember 9, 2024Yes, black diamonds are generally worth something. The specific value of a genuine black diamond depends on its size, measured in carats, as well as its color, cut and clarity. If you own a black diamond or a piece set with one, a certified appraiser or knowledgeable jeweler can give you an idea of how much it may be worth. Shop a variety of black diamond jewelry on 1stDibs.
- 1stDibs ExpertFebruary 22, 2021White, or colorless, diamonds are generally the most valuable diamond variety. Black diamonds are certainly more rare than white ones, but the latter is generally more expensive.
- 1stDibs ExpertApril 5, 2022What black diamond rings symbolize is largely a matter of personal interpretation. Charisma, power, passion and self-assuredness are some of the characteristics commonly associated with black diamond jewelry. Shop a range of diamond gemstone rings from top sellers around the world on 1stDibs.
- 1stDibs ExpertNovember 1, 2023Black diamond engagement rings are popular for many couples. An antique, new or vintage black diamond engagement ring is an edgy, dramatic choice. Just keep in mind that with diamonds, it's all about sparkle, and the darkness of a black stone obscures its fire and brilliance. If the inky opacity of a black diamond seems a bit extreme and you'd like a little light to shine through, consider a gray diamond, which can be cut for maximum brilliance. Brides with a taste for the cool and unusual might also consider salt-and-pepper diamonds, which have white and black inclusions that produce a silvery gray, speckled look. Find black diamond engagement rings on 1stDibs.
- 1stDibs ExpertOctober 5, 2021What a 1-carat black diamond is worth varies according to the cut, type (natural/treated) and the demand and supply. Both natural and treated black diamonds increase in value as demand increases. It ranges from $100 to $3,000 per carat. On 1stDibs, you can find a variety of unique and designer black diamond jewelry & watches from different periods to choose from.
- 1stDibs ExpertNovember 14, 2023To tell if black diamond earrings are real, first examine the surface of the gemstones. Real black diamonds usually have imperfections, while fakes usually appear flawless. Because it can be difficult to identify well-made synthetic gemstones with the naked eye, consider consulting a knowledgeable jeweler, dealer or appraiser for assistance with authentication. Find a variety of black diamond jewelry on 1stDibs.
- 1stDibs ExpertFebruary 22, 2021Black diamonds can make good engagement rings because they symbolize authority, power and passion. They also can be less expensive than clear diamonds.
- 1stDibs ExpertNovember 8, 2023Whether black diamond engagement rings are bad luck depends on a person's individual beliefs. In Italy, rubbing a black stone like a black diamond is considered good luck by some people. However, in India, black diamonds are a traditional symbol of bad luck. Find a variety of diamond engagement rings on 1stDibs.
