This 1.71ct lab-grown round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG451055573 or 451055573. Listed at 11 retailers as of October 29, 2026, with prices from $1,602 to $5,959, a $4,357 spread on the same certified stone. MOH London lists it at $5,959. 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.
