This 1.55ct lab-grown oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG825630610 or 825630610. Listed at 14 retailers as of October 29, 2026, with prices from $399 to $2,928, a $2,528 spread on the same certified stone. Brilliant Earth lists it at $2,928. 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.
