If you could ask the humble zircon, the answer might be mistaken identity and decades of undeserved obscurity.
In the Victorian era, the peak of popularity for zircons, a mined mineral, colorless ones were regularly used as diamond alternatives and blue ones were particularly popular.
“Zircon can come in a wide range of colors — blue, yellow, brown, green and, rarely, a purplish-pink color,” said Nathan Renfro, senior manager of colored stone identification at the Gemological Institute of America.
Then, along came cubic zirconia, an inexpensive synthetic crystal discovered in the 1930s but not developed to the point it could be faceted until 1969.
By the end of the 1970s, it bypassed zircon and became the most common diamond simulant.
