About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded E 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 2566403110. Listed at 21 retailers as of November 2, 2026, with prices from $3,241 to $7,672, a $4,431 spread on the same certified stone. NZ Jewellers lists it at $7,672. 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.
