About this 4.01ct natural marquise diamond

This 4.01ct natural marquise sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 4 retailers as of October 31, 2026, with prices from $143,503 to $184,764, a $41,260 spread on the same certified stone. GS Diamonds lists it at $184,764. 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.
