Spessartite attracted attention in the early 20th century, particularly during the Art Deco period. The geometric, symmetrical designs of the period perfectly complemented the gem’s bright, bold colour.

It should be noted that what is often referred to as “synthetic spessartite” on the market is more likely to be an imitation rather than a genuine synthetic gem. This can lead to confusion, as sellers and jewellers sometimes mistakenly or deliberately use the terms “synthetic” and “imitation” interchangeably.

However, it is important to understand that these terms have distinct meanings and are not at all equivalent.
