I checked in my 2002 edition of Whitburn's Top Pop Albums 1955-2001. The only jazz album that had been on the pop charts (A love supreme never got on any other than the Catalogue chart - and then only in Feb 2001!!!! ) that was certified platinum by RIAA at the time of publication was Dave Brubeck's 'Time out'.
One has to assume that Universal don't count any Columbia record as real jazz
Of course, some albums that weren't platinum in 2002 may be now, but it's a bloody long way to a million and not all the big jazz hits got half a million in sales. Ahmad Jamal's 'But not for me/Live at the Pershing', which was on the rather shorter pop charts from Sep 1958, got to #3 and stayed in the chart for just over 2 years. And that got bugger all in RIAA awards (though that may have been down to Leonard Chess not registering- Motown didn't until the seventies sometime. And Ramsey Lewis didn't get one for the 'In crowd' which sold big in R&B market's as well as in pop).
The only other jazz album from around those days that got a platinum award was 'Kind of blue', which was on the catalogue chart for two and a half years in the nineties. That, too, was never a pop hit. Nor was 'Sketches of Spain' only the catalogue chart for one week (which MAY be the last week reported in Whitburn - it's the same week as 'A love supreme'). That got a gold.
Oh, the Catalogue chart was created to get rid of the rock albums that were staying on the top 200 for too many years to stop the whole thing getting boring. An album qualified if it was selling enough to make the top 200, and had been on that chart for two years but had fallen below #100, or was a reissue.
