Here is something you may find interesting (Underlining and highlighting are mine).
In an archived thread titled,
Lizzie and Jewelry, Harry posted the following on May-4th-03:
… I happened to be reading Lizzie's will so I knew there were entries there.
Apparently Lizzie was quite fond of rings. Rebello lists a few entries as well as the will.
Page 237, from the Fall River Daily Herald, June 23, 1893:
"...On what is usually called the
engagement finger was a ring containing several stones of different colors set after a common design...."
Page 308:
"Lizzie purchased a ring set with three sapphires and two diamonds for $169.00. Between 1899 and 1905, Lizzie purchased four ring sets with diamonds worth a total of $1,545.00 according to the Diamond Record Book of Gifford Jewelry Store." - Source: Fall River Historical Society.
Page 331+ - Lizzie's will left the following:
"Lady's Yellow Gold Tiffany Diamond Ring - $1,500.00

I believe the ring we see on Lizzie's finger in the above photo, is the ring described in the Fall River Daily Herald, on June 23, 1893.
I wonder if this is the ring Andrew gave Lizzie, and because she wore it on her wedding band finger, Person misinterpreted it as an engagement ring.
