The exact origin of the diamond solitaire pendant is challenging to trace, as the design is based on elementary principles: a single diamond held in a simple setting that showcases the stone. This concept can be traced back to the practice of wearing gemstones as amulets or adornments, which is thousands of years old.
The use of diamonds in jewelry became more widespread after significant diamond deposits were discovered in South Africa in the 19th century. The solitaire setting, which uses a single stone, became famous for engagement rings in the late 19th and early 20th centuries. This trend likely influenced the design of other types of jewelry, including pendants.
However, it’s important to note that jewelry design is a creative field with many contributors over time. The “idea” of the diamond solitaire pendant doesn’t necessarily belong to a single person or time period but evolved as part of the broader history of jewelry design.
