Questions About Old Cut Diamond Onyx
  • 1stDibs ExpertMay 5, 2023
    How 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 ExpertApril 5, 2022
    Mine 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, 2021
    Although 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, 2022
    Jewelry 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.
  • 1stDibs ExpertFebruary 22, 2021
    Because 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 ExpertAugust 24, 2021
    Yes, 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, 2021
    Old 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.
  • Like 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.
