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 $1,668 to $8,250, a $6,582 spread on the same certified stone. MOH London lists it at $8,250. 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.
