About this 0.55ct natural radiant diamond

This 0.55ct natural radiant sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6375630167. Listed at 2 retailers as of November 5, 2026, with prices from $1,652 to $3,218, a $1,566 spread on the same certified stone. Diamond Exchange Canada lists it at $3,218. 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.
