This 1.53ct lab-grown oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG451057554 or 451057554. Listed at 8 retailers as of November 5, 2026, with prices from $3,133 to $10,351, a $7,217 spread on the same certified stone. MOH London lists it at $10,351. 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.
