About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2171782007. Listed at 18 retailers as of November 5, 2026, with prices from $3,025 to $8,014, a $4,989 spread on the same certified stone. NZ Jewellers lists it at $8,014. 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.
