About this 0.9ct natural radiant diamond

This 0.9ct natural radiant sits in the just-under-one-carat band, graded H 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 6183759166. Listed at 21 retailers as of October 30, 2026, with prices from $1,647 to $4,284, a $2,637 spread on the same certified stone. NZ Jewellers lists it at $4,284. 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.
