This 1.37ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG395935572 or 395935572. Listed at 3 retailers as of October 28, 2026, with prices from $1,255 to $3,737, a $2,482 spread on the same certified stone. The Diamond Guys lists it at $3,737. 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.
