About this 0.4ct natural radiant diamond

This 0.4ct natural radiant sits in the sub-half-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 5553819239. Listed at 20 retailers as of October 30, 2026, with prices from $539 to $2,022, a $1,483 spread on the same certified stone. NZ Jewellers lists it at $2,022. 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.
