About this 1.23ct natural marquise diamond

This 1.23ct natural marquise sits in the classic one-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 1568201059. Listed at 20 retailers as of November 4, 2026, with prices from $15,187 to $25,015, a $9,828 spread on the same certified stone. NZ Jewellers lists it at $25,015. 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.
