Market Overview: A Tale of Two Markets

The recent JCK Las Vegas show reflected a split diamond market. Long fancies and large round stones sold strongly amid shortages and steady demand. However, many of the “bread-and-butter” goods that constitute the bulk of the industry’s inventory are still struggling.

Trading at the show primarily demonstrated the supply trends that have taken shape. Miners and polished manufacturers have reduced their output over the past year, leading to shortages of select items. Still, tariffs and the ongoing impact of synthetics have hurt business for those with less salable goods.
