About this 3ct lab-grown oval diamond

This 3ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG828671575 or 828671575. Listed at 11 retailers as of November 6, 2026, with prices from $585 to $5,807, a $5,222 spread on the same certified stone. Brilliant Earth lists it at $5,807. 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.
