About this 1.86ct natural radiant diamond

This 1.86ct natural radiant sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2547503175. Listed at 5 retailers as of October 31, 2026, with prices from $17,029 to $21,519, a $4,490 spread on the same certified stone. Blue Nile lists it at $21,519. 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.
