About this 3.01ct natural marquise diamond

This 3.01ct natural marquise sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6243054712. Listed at 13 retailers as of November 4, 2026, with prices from £30,767 to £49,590, a £18,823 spread on the same certified stone. Helzberg Diamonds lists it at £49,590. 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.
