About this 0.57ct natural radiant diamond

This 0.57ct natural radiant sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1509350892. Listed at 2 retailers as of November 1, 2026, with prices from $1,075 to $1,360, a $284 spread on the same certified stone. 77 Diamonds lists it at $1,360. 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.
