Democratization of Diamonds as an Alternative Investment, through Innovation and Technology.



Core Values









Mission Statement


What we do ...

SILIQUA Diamond Capital offers diamonds as a new Alternative and Digital Asset Class. For every diamond a Digital Asset will be created (1:1 backed).

The Digital Assets can be traded, removing all 'red tape' for every transaction. 

Your certified diamonds are physically stored in the free zone in Geneva* (exempt from VAT) and digital accessible globally.

*All diamonds are fully insured, stored and transported by Brinks.


Natural diamonds are uncorrelated to any other asset, currency or legislation. They are highly transportable and guarantee privacy of ownership. With market uncertainty and political instability, investors seek a safe haven in tangible assets.


We have built a Platform to invest in natural diamonds, that uses (DLT) Private Permissioned Distributed Ledger Technology, creating an immutable chain of custody among all trusted partners. 

The owner can digitally request: delivery of his diamonds or offer them back to the market.

Our Clients

Diamonds are Exclusively offered to accredited investors: UHNWI's (Ultra-High Net-Worth Individuals), Private Bankers, Wealth Managers and Family Offices.

Investors will be able to hedge, diversify, store and protect wealth in the most trusted framework.

Natural Diamonds as an Alternative Investment - Digital Assets

The opportunity

Diversify, Store and Protect Wealth

Diamonds have historically proven to be more stable than gold, silver and other commodities*. These characteristics make them a perfect hedge against inflation.

Cutting out the Middlemen

SILIQUA provides investors with direct access to the leading diamond manufacturers of the world. This advantage results in the ability to purchase natural diamonds that normally go to Auction Houses or High-end jewellers at a fraction of their markups or commissions.


Timing of the Markets

SILIQUA combines and bridges different markets; the rising demand of Digital Assets and the Alternative Investment Market combined with the golbal diamond supply / demand gap.



The Offer

SILIQUA offers the most trusted Platform to source or sell certified natural polished diamonds.  The Platform includes the entire ecosystem, including verification, clearing, transportation, customs, insurance, storage and audit.

After verification, your diamonds are fully insured and stored in the free zone in Geneva, Switzerland - VAT exempt*, under BRINKS' custody.

Upon request, BRINKS can organize delivery** of the diamonds to the owner, within a window of 72 hours.

SILIQUA uses Private Permissioned Distributed Ledger Technology to create an immutable chain of custody among all the trusted partners. The diamonds are laser inscribed with the certificate number of GIA (Gemological Institute of America) linking the owner and the diamond through a Digital Asset. No digital asset has a closer tie to the collateral.

The Digital Asset, 1:1 backed with your diamond, can be traded without moving the diamond for every trade, thus removing all the 'red tape' and enabling liquidity.

Direct access and hard ownership of your diamonds

The diamonds are stored, segregated per client and linked directly to the owner. Even in the event of a bankruptcy, change of regulations or other events, the diamonds are your property. No claims can be made by creditors in case of the bankruptcy of the custodian or other service providers.
