About this 1.4ct lab-grown oval diamond

This 1.4ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG847679022 or 847679022. Listed at 7 retailers as of November 1, 2026, with prices from $381 to $1,374, a $992 spread on the same certified stone. MOH London lists it at $1,374. 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.
