Why do people buy jewels?

Why do individuals opt to invest in jewels, often considered a luxurious and exclusive form of asset? Is it merely for the allure of sparkling diamonds and precious gems, or is there a deeper rationale behind such purchases? Could it be a hedge against economic uncertainty, a means of preserving wealth across generations, or perhaps a reflection of personal taste and status? Additionally, what drives the allure of rare and unique jewelry pieces, and how do they compare to other investment opportunities in terms of value appreciation and liquidity?
