About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded H 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 7438685377. Listed at 5 retailers as of October 30, 2026, with prices from $1,327 to $3,364, a $2,037 spread on the same certified stone. Diamond Exchange Canada lists it at $3,364. 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.
