About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5242018471. Listed at 12 retailers as of October 29, 2026, with prices from $8,532 to $12,191, a $3,659 spread on the same certified stone. The Diamond Guys lists it at $12,191. 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.
