About this 3.07ct lab-grown oval diamond

This 3.07ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG605390350 or 605390350. Listed at 12 retailers as of October 28, 2026, with prices from $426 to $1,900, a $1,474 spread on the same certified stone. Rare Carat lists it at $1,900. 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.
