About this 1.81ct natural radiant diamond

This 1.81ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1553402176. Listed at 4 retailers as of October 31, 2026, with prices from $12,567 to $14,753, a $2,186 spread on the same certified stone. Blue Nile lists it at $14,753. 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.
