This 3ct lab-grown round sits in the three to five carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG499106431 or 499106431. Listed at 9 retailers as of November 1, 2026, with prices from $6,413 to $15,404, a $8,991 spread on the same certified stone. MOH London lists it at $15,404. 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.
