Antique jewelry object group: engagement ring (or anniversary ring) Condition: excellent condition Country of origin: Belgium Style: Fifties (of the twentieth century) Period: ca. 1950 Material: platinum Extra information: Betrothal rings were used during Roman times, but werent generally revived in the Western world until the 13th century. The first well-documented use of a diamond ring to signify engagement was by the Archduke Maximilian of Austria in imperial court of Vienna in 1477, upon his betrothal to Mary of Burgundy. Before the 20th century, other types of betrothal gifts were common. Before the end of the 19th century, the bride-to-be frequently received a sewing thimble rather than a engagement ring. This practice was particularly common among religious groups that shunned jewelry. Engagement rings didnt become standard in the West until the end of the 19th century, and diamond rings didnt become common until the 1930s. Now, 80% of the women are offered a diamond ring to signify engagement.
