This 1.45ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG818654273 or 818654273. Listed at 19 retailers as of November 4, 2026, with prices from $313 to $2,364, a $2,051 spread on the same certified stone. Brilliant Earth lists it at $2,364. 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.
