Diamond Prices – January 2021


As predicted we saw an increase in the average price of retail diamonds for December 2020. Consumers reallocated budgets from travel and services toward high-end luxury goods. The holiday period may have rectified the diamond market since the COVID-19 outbreak back in March 2020 but what does 2021 have in store?  Let’s take a closer look at the average price of round diamonds for January 2021 and how the prices differed from December 2020.

Round diamonds continue to be the most popular shape of diamond on the market consuming 74.71% of the market’s popularity. Followed by Oval (5.34%) and Emerald (4.53%) placing third. Round diamonds have increased in popularity over the holiday period, therefore decreasing the percentage of the popularity of the other four shapes.

Year-on-year diamond prices for December 2020 were exactly in line with those of the same month in 2019 – no change at all.  They were badly hit by the pandemic in March and April, when they were 4.8 percent down, but have risen more or less steadily ever since and have now reached pre-Covid levels.
