About this 1.7ct lab-grown oval diamond

This 1.7ct lab-grown oval 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 LG445037770 or 445037770. Listed at 11 retailers as of October 29, 2026, with prices from $1,380 to $5,425, a $4,045 spread on the same certified stone. MOH London lists it at $5,425. 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.
