About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded E colour (colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 1226391120. Listed at 8 retailers as of October 29, 2026, with prices from $17,432 to $24,003, a $6,571 spread on the same certified stone. Yorxs lists it at $24,003. 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.
