This 3ct lab-grown round sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG499190409 or 499190409. Listed at 10 retailers as of November 5, 2026, with prices from $2,262 to $16,077, a $13,814 spread on the same certified stone. MOH London lists it at $16,077. 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.
