About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 260000079694. Listed at 6 retailers as of October 23, 2026, with prices from $3,784 to $7,151, a $3,366 spread on the same certified stone. Wholesale Diamonds Direct lists it at $7,151. 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.
