About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6227965795. Listed at 19 retailers as of October 30, 2026, with prices from $4,736 to $10,473, a $5,737 spread on the same certified stone. NZ Jewellers lists it at $10,473. 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.
