About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG499105205 or 499105205. Listed at 10 retailers as of November 1, 2026, with prices from $904 to $3,556, a $2,652 spread on the same certified stone. MOH London lists it at $3,556. 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.
