About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1565154993. Listed at 11 retailers as of November 5, 2026, with prices from $3,406 to $7,079, a $3,673 spread on the same certified stone. Wholesale Diamonds Direct lists it at $7,079. 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.
