This 1.3ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG451056277 or 451056277. Listed at 11 retailers as of November 3, 2026, with prices from $941 to $4,287, a $3,346 spread on the same certified stone. MOH London lists it at $4,287. 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.
