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 Old European Cut Diamonds
- 1stDibs ExpertMay 5, 2023How old an old European-cut diamond is varies. The old European cut is a precursor to the modern round brilliant cut. The stone appears circular when looked at from the top (because of its low table or largest facet) and has a high crown (the part above the middle of the stone) with larger facets. The tip of the stone, or the culet, is flat instead of pointed. This style was used predominantly in the 19th century, hence the name. It is best to consult a certified appraiser for assistance with dating and identifying antique jewelry. On 1stDibs, find a variety of European-cut diamond jewelry.
- 1stDibs ExpertAugust 24, 2021Yes, old European cut diamonds can be worth more than many other cut diamonds as they are not produced anymore. This cut was developed and popularized between the years 1890 and 1930 and is likely to be found in an antique ring belonging to this period and featuring a round-cut diamond.
- 1stDibs ExpertFebruary 22, 2021Although old European cut diamonds are often priced lower than modern cuts, due to scarcity, they can sometimes be more valuable than modern cut diamonds.
- 1stDibs ExpertApril 5, 2022Jewelry makers stopped using the old European cut for diamond and other gemstone jewelry around 1930. The style was common during the Art Deco period, but the brilliant cut became popular in the years that followed. On 1stDibs, shop a selection of Old European cut diamond gemstone jewelry.
- What is an old European diamond?1 Answer1stDibs ExpertApril 5, 2022An old European diamond is one that features an Old European gemstone cut. This type of cut became popular during the Art Deco period and has a round shape with 58 central facets. You'll find a variety of European cut diamond gemstone jewelry on 1stDibs.
- What is a European cut diamond?1 Answer1stDibs ExpertFebruary 22, 2021European cut diamonds were most popular from the late 19th century to the mid-20th century. They're quite brilliant in terms of shine quality and feature a large culet,small table and round shape.
- How old are mine cut diamonds?1 Answer1stDibs ExpertApril 5, 2022Mine cut diamonds are up to 300 years ago. Mine cut diamonds were popular around the 18th century during Victorian times and are still in high demand today. You’ll find a wide selection of mine cut diamond jewelry on 1stDibs.
- 1stDibs ExpertFebruary 22, 2021Because the old mine cut is no longer used on diamonds, diamonds with this cut are rare and so you can often get quite a lot of money for them. Nevertheless, it is still dependent on the quality of the individual diamonds and on the color, clarity, cut and carat number.
- 1stDibs ExpertFebruary 22, 2021Old mine cut diamonds are usually worth less than old european cut diamonds. Because they are generally 10-15% less expensive, they are often larger than other cut diamonds for engagement rings.
Roman Malakov DiamondsMarch 22, 2021Like any other diamond, an old mine cut diamond's worth depends on a variety of factors. These factors include the 4C's (color, clarity, cut, carat), the overall beauty and "make" of the stone, the demand, supply, etc. On average however, old mine cuts are typically priced slightly lower (around 5-10%) than modern cut diamonds.
