About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded F 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 6541730195. Listed at 29 retailers as of October 31, 2026, with prices from $3,271 to $7,427, a $4,156 spread on the same certified stone. NZ Jewellers lists it at $7,427. 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.
