This 1.81ct lab-grown oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG445036448 or 445036448. Listed at 11 retailers as of October 29, 2026, with prices from $1,424 to $7,386, a $5,962 spread on the same certified stone. MOH London lists it at $7,386. 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.
