About this 1.05ct natural marquise diamond

This 1.05ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6127141306. Listed at 16 retailers as of November 1, 2026, with prices from $11,458 to $20,712, a $9,254 spread on the same certified stone. NZ Jewellers lists it at $20,712. 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.
