About this 0.7ct natural radiant diamond

This 0.7ct natural radiant sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1448374995. Listed at 16 retailers as of October 27, 2026, with prices from $1,439 to $3,980, a $2,540 spread on the same certified stone. NZ Jewellers lists it at $3,980. 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.
