About this 1.85ct natural radiant diamond

This 1.85ct natural radiant sits in the one-and-a-half to two carat band, graded E colour (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 6552180324. Listed at 3 retailers as of October 29, 2026, with prices from $20,587 to $24,084, a $3,498 spread on the same certified stone. Blue Nile lists it at $24,084. 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.
