This 1.38ct lab-grown oval 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 standard cut grade and certified by IGI LG634498617 or 634498617. Listed at 5 retailers as of November 1, 2026, with prices from $475 to $1,663, a $1,188 spread on the same certified stone. Brilliant Earth lists it at $1,663. 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.
