This 1.51ct lab-grown oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG800618212 or 800618212. Listed at 20 retailers as of November 3, 2026, with prices from $414 to $2,300, a $1,886 spread on the same certified stone. Brilliant Earth lists it at $2,300. 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.
