About this 1.7ct lab-grown round diamond

This 1.7ct lab-grown round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG442067091 or 442067091. Listed at 10 retailers as of October 25, 2026, with prices from $1,227 to $5,650, a $4,423 spread on the same certified stone. MOH London lists it at $5,650. 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.
