About this 3ct natural marquise diamond

This 3ct natural marquise sits in the three to five carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2486939533. Listed at 5 retailers as of November 5, 2026, with prices from $60,854 to $76,122, a $15,268 spread on the same certified stone. The Diamond Guys lists it at $76,122. 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.
