This 0.7ct 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 LGF6G63383 or F6G63383. Listed at 2 retailers as of November 4, 2026, with prices from £658 to £1,123, a £466 spread on the same certified stone. 18carati lists it at £1,123. 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.
