About this 1.54ct natural heart diamond

This 1.54ct 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 2484824894. Listed at 20 retailers as of October 28, 2026, with prices from $11,417 to $20,258, a $8,841 spread on the same certified stone. Queensmith lists it at $20,258. 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.
