About this 0.91ct lab-grown oval diamond

This 0.91ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG602387870 or 602387870. Listed at 5 retailers as of October 28, 2026, with prices from $273 to $467, a $194 spread on the same certified stone. Diamond Heaven lists it at $467. 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.
