About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2155642428. Listed at 12 retailers as of October 30, 2026, with prices from $5,263 to $11,835, a $6,572 spread on the same certified stone. NZ Jewellers lists it at $11,835. 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.
