About this 1.21ct natural asscher diamond

This 1.21ct natural asscher sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2121393022. Listed at 9 retailers as of November 6, 2026, with prices from $5,423 to $9,224, a $3,801 spread on the same certified stone. Yorxs lists it at $9,224. 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.
