This 1.01ct lab-grown oval sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436074859 or 436074859. Listed at 11 retailers as of October 29, 2026, with prices from $577 to $3,122, a $2,545 spread on the same certified stone. MOH London lists it at $3,122. 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.
