About this 1.04ct natural radiant diamond

This 1.04ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1505100272. Listed at 9 retailers as of November 6, 2026, with prices from $3,562 to $4,787, a $1,225 spread on the same certified stone. Yorxs lists it at $4,787. 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.
