About this 1.52ct natural heart diamond

This 1.52ct 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 6565414464. Listed at 4 retailers as of October 31, 2026, with prices from £3,239 to £3,851, a £613 spread on the same certified stone. Blue Nile lists it at £3,851. 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.
