About this 4.29ct natural marquise diamond

This 4.29ct natural marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2145040645. Listed at 7 retailers as of November 4, 2026, with prices from $189,043 to $296,398, a $107,354 spread on the same certified stone. MOH London lists it at $296,398. 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.
