Diamonds are well-known for being the world’s most precious gemstones in the global jewelry market. Major diamond producing companies around the world have witnessed stable growth in their revenues, thanks to the demand for diamond jewelry, such as engagement rings, diamond necklaces, diamond earrings and diamond bracelets.
The global demand for diamond jewelry was worth over $80 billion in 2016, while the US is the largest diamond jewelry market in the world, representing nearly half of the global diamond sales. The thriving market has also stimulated diamond production. According to the latest data presented by diamond expert Paul Zimnisky, the world’s total mined diamond production is estimated to be 142.3 million carats or $15.6 billion worth in 2017, representing a 11.5% increase in carat volume produced over 2016 and an 9.9% increase in total value produced.
