About this 1.02ct lab-grown oval diamond

This 1.02ct lab-grown oval sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG447000426 or 447000426. Listed at 10 retailers as of November 5, 2026, with prices from $1,064 to $7,171, a $6,106 spread on the same certified stone. MOH London lists it at $7,171. 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.
