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 LG754510325 or 754510325. Listed at 16 retailers as of November 3, 2026, with prices from $166 to $1,067, a $901 spread on the same certified stone. Flawless Fine Jewelry lists it at $1,067. 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.
