About this 1.65ct natural heart diamond

This 1.65ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 780633158. Listed at 2 retailers as of November 2, 2026, with prices from $8,463 to $10,017, a $1,555 spread on the same certified stone. 77 Diamonds lists it at $10,017. 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.
