This 0.91ct lab-grown oval sits in the just-under-one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG800644948 or 800644948. Listed at 4 retailers as of October 31, 2026, with prices from $288 to $600, a $312 spread on the same certified stone. Taylor and Hart lists it at $600. 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.
