This 1.53ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1553492009. Listed at 3 retailers as of November 1, 2026, with prices from $9,718 to $12,966, a $3,247 spread on the same certified stone. 77 Diamonds lists it at $12,966. 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.
