This 3ct lab-grown round sits in the three to five carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG480148932 or 480148932. Listed at 8 retailers as of November 5, 2026, with prices from $12,089 to $25,464, a $13,375 spread on the same certified stone. MOH London lists it at $25,464. 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.
