About this 1.3ct natural radiant diamond

This 1.3ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2378005480. Listed at 10 retailers as of November 4, 2026, with prices from $6,013 to $11,587, a $5,574 spread on the same certified stone. MOH London lists it at $11,587. 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.
