5 diamond stocks to watch

Ready to invest in the precious gem industry? Learn how to invest in diamond stocks in just a few steps.

The best diamond stocks depend on your portfolio and investment goals — while volatility can be ideal for day traders, long-term investors will want to look to stocks with steadier gains over time.

You'll also want to consider which stocks are easy to buy. Many diamond stocks are located on non-US exchanges, which means you'll need a brokerage account that offers access to international stocks. Different brokerages offer access to different exchanges, so if you're interested in a specific non-US stock, you'll want to check if it's available through your brokerage account.

Bottom line

While it's possible to turn a profit investing in diamond stocks, keep in mind that—like any investment—diamond stocks are not immune to risk. These stocks are subject to fluctuating conditions both in the market and in the precious gem industry, so carefully vet your picks before you invest. If you're new to investing or if it's been a while since you've taken a critical look at your investment accounts, compare brokers to make sure you're getting the best trading features for your needs.
