About this 0.91ct natural asscher diamond

This 0.91ct natural asscher sits in the just-under-one-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 6542430400. Listed at 4 retailers as of October 31, 2026, with a relatively tight 13% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
