About this 1.74ct lab-grown round diamond

This 1.74ct lab-grown round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG754510419 or 754510419. Listed at 13 retailers as of October 29, 2026, with prices from £155 to £775, a £620 spread on the same certified stone. MOH London lists it at £775. 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.
