About this 1.23ct natural marquise diamond

This 1.23ct natural marquise sits in the classic one-carat band, graded I colour (near-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 2416475837. Listed at 17 retailers as of November 1, 2026, with prices from $5,800 to $11,197, a $5,397 spread on the same certified stone. NZ Jewellers lists it at $11,197. 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.
