About this 0.91ct natural oval diamond

This 0.91ct natural oval 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 1555721585. Listed at 5 retailers as of November 5, 2026, with prices from $909 to $1,338, a $429 spread on the same certified stone. GemTrove lists it at $1,338. 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.
