This 1.87ct lab-grown round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG634412486 or 634412486. Listed at 10 retailers as of November 1, 2026, with prices from $471 to $1,219, a $748 spread on the same certified stone. MOH London lists it at $1,219. 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.
