About this 1.42ct lab-grown oval diamond

This 1.42ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG825631417 or 825631417. Listed at 18 retailers as of October 23, 2026, with prices from $493 to $1,400, a $907 spread on the same certified stone. Brilliant Earth lists it at $1,400. 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.
