About this 0.43ct natural cushion diamond

This 0.43ct natural cushion sits in the sub-half-carat band, graded F 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 2225869411. Listed at 13 retailers as of November 2, 2026, with prices from $476 to $1,658, a $1,182 spread on the same certified stone. Diamond Exchange Canada lists it at $1,658. 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.
