This 1.51ct lab-grown round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436045567 or 436045567. Listed at 10 retailers as of October 29, 2026, with prices from $1,099 to $6,356, a $5,257 spread on the same certified stone. MOH London lists it at $6,356. 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.
