About this 1.12ct lab-grown oval diamond

This 1.12ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG703511273 or 703511273. Listed at 7 retailers as of October 26, 2026, with prices from $284 to $1,224, a $940 spread on the same certified stone. MOH London lists it at $1,224. 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.
