About this 1.87ct lab-grown oval diamond

This 1.87ct lab-grown oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG790601831 or 790601831. Listed at 11 retailers as of October 31, 2026, with prices from $517 to $1,960, a $1,443 spread on the same certified stone. Brilliant Earth lists it at $1,960. 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.
