This 1.13ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG508138146 or 508138146. Listed at 5 retailers as of November 4, 2026, with prices from $488 to $1,309, a $821 spread on the same certified stone. MOH London lists it at $1,309. 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.
