About this 0.86ct natural radiant diamond

This 0.86ct natural radiant sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1458165105. Listed at 17 retailers as of October 30, 2026, with prices from $3,155 to $8,058, a $4,904 spread on the same certified stone. NZ Jewellers lists it at $8,058. 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.
