Silver prices hit a two-year high above $21 per ounce on Monday, as precious metals continue to gain from the safe-haven rally following the U.K. referendum.
Some investors say silver has further to run and may be a better bet than gold.
"Silver is a metal that most people don't really think about when they think about precious metals, but it does have this dual property towards both an industrial metal and a precious metal. So many of the reasons that investors chose to invest in gold, silver has many of those properties, at the same time as having a lot of demand coming from industrials," PureFunds CEO Andrew Chanin told CNBC last week.
Spot silver prices have gained around 19 percent since referendum day on June 23 to trade above $21 per ounce on Monday, before paring some gains to trade at around $20.40. The rally has accelerated since June 29.
By comparison, spot gold has rallied by 7.8 percent in the same period to around $1,351 per ounce.
