About this 1.87ct natural radiant diamond

This 1.87ct 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 1219042376. Listed at 4 retailers as of November 1, 2026, with prices from $17,791 to $25,431, a $7,640 spread on the same certified stone. MOH London lists it at $25,431. 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.
