About this 0.8ct natural radiant diamond

This 0.8ct natural radiant sits in the just-under-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 1267798317. Listed at 7 retailers as of October 31, 2026, with prices from $2,617 to $4,927, a $2,311 spread on the same certified stone. Cape Diamonds lists it at $4,927. 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.
