About this 1.9ct natural radiant diamond

This 1.9ct natural radiant sits in the one-and-a-half to two carat band, graded G 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 2458144036. Listed at 12 retailers as of October 26, 2026, with prices from $5,784 to $10,216, a $4,432 spread on the same certified stone. MOH London lists it at $10,216. 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.
