About this 1ct natural marquise diamond

This 1ct 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 7556051351. Listed at 7 retailers as of October 30, 2026, with prices from $1,904 to $5,010, a $3,107 spread on the same certified stone. NZ Jewellers lists it at $5,010. 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.
