About this 0.54ct natural radiant diamond

This 0.54ct natural radiant sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3425352015. Listed at 10 retailers as of November 6, 2026, with prices from $483 to $1,327, a $844 spread on the same certified stone. MOH London lists it at $1,327. 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.
