The Hardest Asset Is Now Liquid

Safely add diamonds to your investment portfolio via blockchain technology

A Blockchain-Based Diamond NFT Marketplace

Non-fungible Token Hard Asset Diamond Investment

Icecap uses Ethereum-based, non-fungible tokens to represent ownership of individual diamonds.
You trade the tokens without friction while the diamonds are vaulted and insured.


Preserve Your Investment Value​

By trading the diamond’s token in a frictionless environment, you buy and sell close to wholesale price. Thus your investment doesn’t lose half its value the moment you “drive it out of the showroom.”

Always Know Your Liquidation Price​

Icecap’s marketplace of ongoing bids (at least one bid is guaranteed on every token) means you always know the value of your investment, and can liquidate for that value at any time, with a mouse click.

Enjoy Your Asset Before You Trade it

If you wish, you can redeem your token and take delivery of your diamond—perhaps to adorn a loved one. That way you’re investing in both a hard asset, and your relationship. You can re-tokenize later if you decide to sell.

What Makes Diamonds a Great Asset?

The Hardest Asset

Because diamonds track generally with gold and silver prices, but in a less volatile manner, they are an ideal way to diversify your hard asset portfolio.

Portable and Concealable

A million dollars of diamonds can travel discretely, whether in a pocket or worn as jewelry. That much wealth in gold could not be carried by one person.

Beloved and Beautiful

When not concealed, diamonds thrive in plain sight. More than a store of wealth, they are wealth—and can be enjoyed by you or a loved one, purely for their beauty.

How it Works

You buy Icecap Diamond tokens at in exchange for USDC. Each token represents a specific diamond in an insured vault. Tokens are sold directly by Icecap, as well as by other users.

Once you’ve bought a token, you can either:

  • Keep it as a token, so it can be easily traded.
  • Redeem the token and physically receive your diamond. At that point, the diamond is completely yours. The token is destroyed, but you can retokenize your diamond if you decide to sell it later.

To sell the token, simply accept an offer that someone has made for your token on OpenSea. You can also set an asking price and wait for bids to come in.

Diamond trading has never been this easy.
