This 0.42ct natural radiant sits in the sub-half-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551816127. Listed at 5 retailers as of October 30, 2026, with prices from $510 to $1,732, a $1,222 spread on the same certified stone. NZ Jewellers lists it at $1,732. 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.
