About this 16.48ct lab-grown oval diamond

This 16.48ct 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 7471895740. Listed at 10 retailers as of October 27, 2026, with prices from $6,820 to $45,493, a $38,673 spread on the same certified stone. Do Amore Diamonds lists it at $45,493. 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.
