About this 0.99ct natural oval diamond

This 0.99ct natural oval sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5172496817. Listed at 5 retailers as of October 31, 2026, with prices from $3,521 to $5,339, a $1,818 spread on the same certified stone. Cape Diamonds lists it at $5,339. 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.
