About this 0.51ct natural asscher diamond

This 0.51ct natural asscher sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6375642132. Listed at 12 retailers as of November 4, 2026, with prices from $688 to $1,863, a $1,175 spread on the same certified stone. MOH London lists it at $1,863. 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.
