This 0.45ct lab-grown heart sits in the sub-half-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847661828 or 847661828. Listed at 7 retailers as of October 26, 2026, with prices from £95 to £620, a £525 spread on the same certified stone. MOH London lists it at £620. 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.
