About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6243093257. Listed at 13 retailers as of October 31, 2026, with prices from €1,966 to €3,670, a €1,704 spread on the same certified stone. Helzberg Diamonds lists it at €3,670. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
