About this 11.46ct lab-grown oval diamond

This 11.46ct lab-grown oval sits in the over five 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 6462165454. Listed at 9 retailers as of October 27, 2026, with prices from $3,494 to $29,379, a $25,885 spread on the same certified stone. Brilliant Earth lists it at $29,379. 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.
