This 1.7ct lab-grown round sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG451055580 or 451055580. Listed at 9 retailers as of November 5, 2026, with prices from $3,267 to $10,254, a $6,987 spread on the same certified stone. MOH London lists it at $10,254. 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.
