Questions About Square Cut Gemstone
  • 1stDibs ExpertOctober 19, 2021
    A sugarloaf cut gemstone or cabochon cut involves one of the oldest stone-cutting techniques. It sees that the doming and polishing of a gemstone are carried out, which gives it a flat edge that is best suited for a fine jewelry setting. It is most popular for displaying the natural colors of stones in their pure state. Shop a diverse range of vintage sugarloaf cut gemstone rings on 1stDibs today.
  • 1stDibs ExpertApril 5, 2022
    Emeralds are frequently cut into squares due to their properties. Because they are brittle, the gemstones benefit from stronger rectangular and square shapes. Also, these cuts tend to hide the natural blemishes found in many emeralds. Shop a large selection of emerald gemstone jewelry on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    No, a square emerald cut is not the same as an asscher cut. Although they have the same basic shape and are both step cuts that maximize clarity, the asscher cut shows off a sharper angle at the corners. Shop a wide variety of gemstone jewelry on 1stDibs.
