Polished diamond imports into the US have declined once again. In 2017, the US imported $21.7 billion worth of loose polished diamonds, a 3% decline compared to imports in 2016. The sad part is that this marks the third consecutive year of declines in the import of polished diamonds. In 2014, imports stood at $24 billion. In 2015, they fell 4.6% to $22.9 billion, and in 2016, they declined yet again, this time by 2.5% to $22.3 billion. Cumulatively, imports declined by 10% during the four-year period.
