About this 1.05ct lab-grown oval diamond

This 1.05ct lab-grown oval sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG764658604 or 764658604. Listed at 5 retailers as of October 26, 2026, with prices from £230 to £671, a £441 spread on the same certified stone. MOH London lists it at £671. 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.
