About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of October 31, 2026, with prices from $16,352 to $20,496, a $4,144 spread on the same certified stone. Blue Nile lists it at $20,496. 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.
