This 0.72ct lab-grown round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LGF5D99139 or F5D99139. Listed at 2 retailers as of November 4, 2026, with prices from £657 to £1,155, a £498 spread on the same certified stone. 18carati lists it at £1,155. 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.
