About this 1.05ct natural marquise diamond

This 1.05ct 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 7551521933. Listed at 6 retailers as of October 30, 2026, with prices from $4,542 to $10,520, a $5,978 spread on the same certified stone. NZ Jewellers lists it at $10,520. 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.
