Are diamonds worth more now than 40 years ago?

Well, that's an interesting question! Diamonds have always been seen as a symbol of luxury and status, and their value has fluctuated over time depending on various factors such as supply and demand, mining costs, and global economic conditions. But when it comes to comparing the value of diamonds now to 40 years ago, it's not as simple as a straightforward "yes" or "no" answer. In some ways, diamonds may be worth more now due to inflation and other economic factors that have driven up prices over time. However, other factors such as advancements in diamond mining technology and increased supply could potentially lower their relative value. So, to really answer the question, we would need to take a closer look at the specific diamond market and compare data from 40 years ago to today. Without that information, it's difficult to give a definitive answer. But suffice it to say that the value of diamonds is complex and depends on a variety of factors.
