Why Track Diamond Prices?

Diamond prices are an interesting topic because they are a reflection of global economic trends. For example, diamond prices increased during the Great Depression as people sought to invest their money in something that would hold its value. Similarly, diamond prices increased during the 1970s as a result of inflation. By understanding how diamond prices have changed over time, we can gain insight into the health of the global economy.

Delving into historical diamond market pricing reveals the interplay between supply chain dynamics, technological innovations in diamond mining, and changes in consumer preferences over time. For example, the emergence of lab grown or synthetic diamonds has introduced a new variable in the pricing equation, challenging the dominance of natural diamonds.
