About this 1.02ct natural oval diamond

This 1.02ct natural oval sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2567596159. Listed at 14 retailers as of October 31, 2026, with prices from $3,236 to $6,043, a $2,807 spread on the same certified stone. Helzberg Diamonds lists it at $6,043. 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.
