About this 0.51ct natural asscher diamond

This 0.51ct natural asscher sits in the half to three-quarter carat band, graded J 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 2506879455. Listed at 6 retailers as of November 5, 2026, with prices from $696 to $2,253, a $1,557 spread on the same certified stone. Diamond Exchange Canada lists it at $2,253. 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.
