Investors who talk about the great potential of the diamond industry now have a chance to put their money where their mouth is.

The first exchange-traded fund to focus on the diamond and gem industry premiered on the New York Stock Exchange Nov. 29.

The PureFundsISE Diamond/Gemstone ETF, which trades under GEMS, has holdings for companies involved in the gemstone industry, including exploration, production, or sales of precious stones.

Its top 10 holdings include Signet, Tiffany, Chow Tai Fook, Harry Winston, Blue Nile, Luk Fook Holdings, Petra Diamonds, Chow Sang Sang, Anglo American, and Gem Diamonds.

“Diamonds and other gemstones have traditionally been a difficult asset to invest in because there is no spot or futures market, so we developed an ETF that exclusively invests in companies that produce, refine, sell, or hold gemstone inventory,” said Paul Zimnisky, CEO of PureFunds, in a statement. “We believe new demand for diamonds and other gemstones will continue to come from developing parts of the world where the trend of gifting gemstones is catching on fast. Investors are also driving demand, as gemstones are being bought as a hedge against inflation, the same way precious metals are. We expect the companies in this fund to benefit if the demand for gemstones remains favorable.”
