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 IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG726521154 or 726521154. Listed at 21 retailers as of October 28, 2026, with prices from £649 to £2,698, a £2,049 spread on the same certified stone. Rare Carat lists it at £2,698. 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.
