About this 1.59ct natural heart diamond

This 1.59ct natural heart sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555565353. Listed at 7 retailers as of November 6, 2026, with prices from $1,876 to $3,513, a $1,637 spread on the same certified stone. Wholesale Diamonds Direct lists it at $3,513. 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.
