This 0.45ct lab-grown round sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG462173063 or 462173063. Listed at 9 retailers as of October 29, 2026, with prices from $412 to $2,055, a $1,643 spread on the same certified stone. MOH London lists it at $2,055. 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.
