The GEM ICO is designed to make it easy to invest in high-end gems and jewelry by tokenizing an exceptional collection of gemstones and allowing token holders to trade co-ownership shares of that collection on the Ethereum blockchain.

Hard Asset Revolving ICOs aim to generate the type of “stable token” deeply craved for in the crypto sphere by (i) using the notarization function in a revolutionary way in order to publicly establish token holders’ rights and (ii) capitalizing on tangible hard assets such as high-end gemstones known not only for their resilience and good performance over the years, but as a store of value over the centuries.


As an asset class, high-end gemstones are plagued by significant entry barriers such as the expertise required to acquire an investment-grade stone, the challenge of secure storage, the lack of liquidity and the required investment amount which entails an important opportunity cost. The GEM ecosystem will quickly resolve these disadvantages, opening this market to everyone.


GEM token holders will directly benefit from the expertise of a dedicated team of jewelry specialists whose duty will be to travel the world, constantly monitor the market and liaise with advisors and specialists to source the most exceptional gems and jewelry collection.


At any given time, depending on the investment cycle, the assets co-owned by the token holders may be in the form of cryptocurrency (the funds will be held in cryptocurrency while the Collection is being formed), official currencies (the cryptocurrency will be converted into official currencies, for a very short time before a particular asset is acquired) or hard assets, namely the GEM Collection. Thanks to an unprecedent level of transparency, the token holders will have a comprehensive view of their assets, including the proof of balance for each category of assets.

Looking foranother ICO?


The price of collectible classic cars has more than quadrupled over the past ten years. Authenticity, scarcity and ultimately the legend surrounding unique pieces are the primary value drivers in this market. The CAR ICO is opening mainstream access to this exclusive asset class, enabling investors not only to diversify their portfolio but also to hedge their risk against financial market instability.

Tokenizing a 250 GTO Ferrari is now a reality.


The WINE Collection will primarily include the greatest, and most hard to find wines from producers in Burgundy, Bordeaux, and Piedmont, but also lesser-known-however-exceptional quality vintages, together with a number of rare spirits – some of which are no longer being produced.
Walking through the WINE Collection will be like visiting the most exclusive vineyards in the world, as well as exotic forays to distilleries in Japan and the Scottish Highlands.
