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 LG499190402 or 499190402. Listed at 9 retailers as of November 3, 2026, with prices from $8,169 to $19,621, a $11,452 spread on the same certified stone. MOH London lists it at $19,621. 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.
