About this 1.3ct natural oval diamond

This 1.3ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 833690428. Listed at 19 retailers as of October 30, 2026, with prices from $5,219 to $11,677, a $6,458 spread on the same certified stone. NZ Jewellers lists it at $11,677. 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.
