This 12.03ct lab-grown heart sits in the over five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG683584066 or 683584066. Listed at 6 retailers as of October 31, 2026, with prices from $5,068 to $16,872, a $11,803 spread on the same certified stone. Taylor and Hart lists it at $16,872. 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.
