This 1.81ct lab-grown oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436074872 or 436074872. Listed at 10 retailers as of October 31, 2026, with prices from $1,000 to $4,991, a $3,991 spread on the same certified stone. MOH London lists it at $4,991. 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.
