The Rapaport Group has released its Diamond Price Statistics Annual Report for 2020, evaluating the performance of polished-diamond prices. The report provides an in-depth analysis of the past year’s trends, and compares the price changes within specific diamond categories.
The Rapaport Diamond Index (RDI™), which tracks changes in the Rapaport Price List, fell for most categories in 2020, reflecting the dramatic decline in activity across the diamond industry when Covid-19 spread across the globe. Yet, the RapNet Diamond Index (RAPI™) rose in many size ranges, reflecting an improvement in average asking prices on RapNet. Average discounts were lower at year-end versus 12 months prior, meaning that demand was stronger relative to supply available in the market.
The pandemic brought much volatility to the diamond sector, with periods of little-to-no trading during the lockdowns and a gradual rise in demand during the surprisingly positive holiday season.
The Rapaport Diamond Price Statistics Annual Report charts the progression of polished prices for various sizes, both in 2020 and over the past 41 years. In doing so, it provides a complete study of the global diamond market’s history, as well as its current standing.
Also included is a diamond investment analysis detailing how various diamond categories have performed over the past 10 years in relation to other common investment instruments.
