About this 2.5ct lab-grown oval diamond

This 2.5ct lab-grown oval sits in the two to three carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG445036146 or 445036146. Listed at 10 retailers as of October 29, 2026, with prices from $1,500 to $8,448, a $6,948 spread on the same certified stone. MOH London lists it at $8,448. 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.
