About this 3ct lab-grown round diamond

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 LG478113815 or 478113815. Listed at 9 retailers as of November 3, 2026, with prices from $4,592 to $11,030, a $6,438 spread on the same certified stone. MOH London lists it at $11,030. 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.
