About this 2.5ct lab-grown round diamond

This 2.5ct lab-grown round sits in the two to three carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG478123471 or 478123471. Listed at 12 retailers as of October 27, 2026, with prices from $3,288 to $12,135, a $8,847 spread on the same certified stone. MOH London lists it at $12,135. 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.
