About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6445655444. Listed at 6 retailers as of October 26, 2026, with prices from £4,602 to £6,982, a £2,380 spread on the same certified stone. Wholesale Diamonds Direct lists it at £6,982. 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.
