This 1.02ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG829618880 or 829618880. Listed at 8 retailers as of October 29, 2026, with prices from $436 to $1,191, a $756 spread on the same certified stone. MOH London lists it at $1,191. 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.
