The Diamond Marketplace for Hard-Asset Investors

As a hard-asset investor, you seek protection against inflation.

But, even though diamonds are the most portable of the hard assets, you’ve probably avoided them because:

  • Retail store markups mean a big loss when you’re ready to sell. (High bid/ask spread)
  • How do you sell? A pawnshop is not a good option.
  • Tracking value over time is difficult with non-fungible assets like diamonds.

Earthplanet Minerals solves these historic problems with a technology-based, two-way marketplace designed for the needs of investors, not jewelry buyers.

Investment Focus


At Earthplanet Minerals, we believe that focus is the key to success. We invest in two asset types:

Class-A
Raw Minerals
Industrial CVD Diamonds

We form joint ventures with experienced developers/Miners with proven track records of success. We look for long-term relationships that can grow over time. With the strength of the Witwatersrand Basin and as part of our global strategy we have access to consistent multiple equity sources.

Benefits of Earthplanet Minerals Marketplace


Preserve Your Investment Value

By trading diamonds in a near-frictionless environment, you buy and sell close to wholesale value. Thus you don’t lose half your value from the moment you “drive it out of the showroom.”

Always Know Your Diamond's Value

Our platform uses patent-pending virtual-fungibility™ technology to track your diamond’s approximate value from the time it was purchased, and lets you re-list your diamond with a few mouse clicks.

Enjoy Your Asset Before You Trade

When you buy a diamond, you can choose to either vault it, or take delivery. Unlike bullion, diamonds can be enjoyed as jewelry while still serving your portfolio. Return your diamond to the vault when you wish to sell.


How it Works

Trade Close to Wholesale Price.

Earthplanet Minerals sells newly-issued diamonds at a 10% margin over wholesale cost. The industry average for diamond e-tailers is about 25%.

Enjoy Investment-Grade Liquidity.

Earthplanet Minerals screens its diamonds to maximize their liquidity. “Investment-Grade” diamonds should be easy to sell, not just easy to buy.

Access a 2-Way Marketplace.

Earthplanet Minerals operates a buy/sell marketplace in which investment-buyers, market-makers, and diamond industry wholesalers compete against each other to minimize spreads, and maximize liquidity.

Leverage Patent-Pending Technology.

Earthplanet Mineral’s proprietary virtual-fungibility technology makes pricing transparent, and delivers to you—the hard asset investor—a close to “metals trading” experience.

Take Delivery Anytime.

If you chose to vault your diamond, you will receive a warehouse receipt, which you can redeem at anytime and take delivery of the diamond—to store privately or enjoy as jewelry while in your portfolio. Return your diamond to the vault when you’re ready to sell.
