About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6562628874. Listed at 4 retailers as of October 31, 2026, with prices from $18,497 to $21,714, a $3,217 spread on the same certified stone. Aurelinne lists it at $21,714. 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.
