This 1.57ct 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 LG440012265 or 440012265. Listed at 9 retailers as of October 31, 2026, with prices from $1,239 to $6,183, a $4,945 spread on the same certified stone. MOH London lists it at $6,183. 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.
