This 1.27ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG763605026 or 763605026. Listed at 14 retailers as of November 1, 2026, with prices from $235 to $1,365, a $1,130 spread on the same certified stone. MOH London lists it at $1,365. 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.
