The Birth Diamond is made up of two parts, the Diamond itself and its basis.

The foundation:

The basis of the Diamond is the foundation on which the Diamond is built.

On the left, you have the facets that are initially hidden until they are revealed. These facets are called "the soul's birth intention", “the Soul Call”, “the Hidden resource” “the Hidden Challenge” and “the Contradiction”.

On the right, you have the dominant parts of the character, the visible core. These are psychological schemes and resources that are always available for you and that you always use consciously to do what you have come on earth to experience. Your visible core is made up of your natural temper, your deep motivation, your key resource, your expression number and your life axis or self-realisation number. The self-realization card describes a main psychological tendency and summarises the Birth Diamond. At the center of the Diamond’s basis, you have the “House of the year” or annual card. It describes the climate or dominant energy existing during the year.

History of the Birth Diamond !

The birth Diamond follows the flow of self-knowledge tools that have being created in the past decades. It was created in Lyon, France during spring 2011/2012.


In China, there is a 3000 years old tradition that associates numbers with symbols. This tradition gave birth to a book called the I Ching, where 64 numbers are associated with the typical situations that come up over and over in human life.

The modern Tarot is a “Christianised” version of the first 22 numbers of the I Ching. According to current known information, the first card games were created in China around the seventh century AD. These card decks were inspired by the existing Chinese symbols. The card decks rapidly reached India where they were adapted to Hindu beliefs.

Trade between India and the Muslim empire, then in full expansion, allowed card decks to spread throughout the Muslim empire.

The card decks were adapted to Muslim traditions under the Turkish Mamelouks, who runned the empire. One can find Muslim card decks from the ninth century AD.

They are divided into 4 series of 13 cards (Jars, coins, spears and wands), with a Vizir, a vice Vizir and a queen. Crusaders and merchants, especially Spanish and Italian, brought these card decks back to Europe.

They were then known as “Naib card decks”. Although many attempts were made by the Christian churches to forbid and banish these games, they became more and more popular, especially in Italy between 1300 AD and 1400 AD.

It is thus in the towns of Italy that were created the first Tarot decks, which combined the classical card decks to which were added 22 extra cards or assets. According to Italian historians, these new tarot decks with 22 extra cards called “major Arcanum” or “triumphs” were created and financed by the ruling Italian families.

The origin of the name “Tarot” comes from the Italian word “Tarocco” which itself comes from the Arab word “turuk” meaning “four paths”. This word was linked to Sufi groups, who were the religious elite of the Muslim religion.

Many different tarot decks were created in a short time span, throughout all of Italy, between 1450 and 1550 AD. The best know ones were the Visconti Tarot, the Bologna Tarot, the Sicilian Tarot, the Parlanti Tarot, the Pasquinata Tarot and the Milanese Tarot.

The order in which the cards were classified varied considerably until the order from the Milanese tarot decks was adapted as the official order. The “Tarot de Marseille”, used in France, and from which many tarot decks are based, was inspired by a Tarot deck created in Lyon in 1557 by a man called Geoffroy de Catelin who used a Milanese tarot deck.


The tarot became more and more used, especially between 1800 and 1900, in France and in England. Various “truth seekers”, who called themselves “occultists” and who were inspired by Jewish and Christian traditions, used the tarot as a tool for predicting the future.

In France at that time, a group of these “occultists”, amongst which were Mr De Gaita, Mr De Lorraine, « Papus » and Mr Oswald Wirth, created an organization called the “Rosicrucian Cabalistic Order”.

They also created a tarot deck called the “Oswald Wirth Tarot Deck” and a spread with five cards called the Cross spread, which has the shape of a cross, a Christian symbol that was also the symbol of their organization.

This spread became very popular in France and still is today. It helped Tarot cards to become widely used as a means to communicate with the subconscious mind.


The tarot deck was strongly influenced by numerology since the very beginning of its making. The significance of each card highly depends on the number it carries. Numerology is the science of numbers. It is derived from mathematics and exists in Europe since antique Greece, mainly thanks to Mister Pythagoras.

It is the art of giving numbers a symbolic meaning and then of interpreting these numbers by extracting information about a person’s life though his first name, family name and birth date. Numerology was well known to Muslim culture and to Jewish cabbala. Interest in numerology grew quickly, in England and in USA, between 1800 and 1940. In France, Mister Robert Markab helped numerology become popular with a first book written in 1938.

In England and in France, the group of seekers who called themselves “occultists” naturally linked tarology and numerology. At that stage, the first component of a birth date, the day of birth, was linked with number one and symbolized the conscious personality asserting itself to live its life. That’s exactly what the Magician, first card of the tarot deck, does. The second component of the birth date, the month, was linked with the High Priestess, with the hidden part of the personality who holds all the keys and treasures that can grant access to the secrets and mysteries of life. The third component of the birth date, the year of birth, was connected to the Empress and to one’s ability to cope with the outside world, mostly though understanding of human nature and human laws and through intelligence and adaptability.

These three components assembled together gave rise to a fourth component that was connected to the Emperor, who builds up his empire and accomplishes his destiny. And then the first four components were added together to give rise to a fifth component that gave a spiritual meaning to the first four components. This fifth component was linked with the High Priest and to the key teachings needed to find God.

Numerology gradually grew with new indicators. Adding the day and the month of birth describes one’s inner personality and wealth (House 2 of the birth Diamond) while adding the month and the year of birth gives rise to how one uses one’s inner treasures to adapt to the outside world, to an outer personality and wealth (House three of the birth Diamond). Adding inner and outer wealth gave rise to one’s natural temper. Asking for the full name and for the birth date became a habit for most people using tarot.


In 1974, at Sausalita in California, Jack and Rae Hurley, who practiced tarot, and illustrator John Horler, discovered Buddhism through a Tibetan Lama and experienced the “new age “ culture of the “60s” and “70s”. They created the « New Tarot Deck » or « Psycho-Tarot » which was published by Tarocco. This deck was made up of 78 black and white cards and it was specifically designed to help one solve difficult situations and psychological issues.

The pictures and symbols on the cards were intended to help the consultant connect his conscious and unconscious minds so as to understanding why he personally created the situation he now experienced and how to solve his problems. A booklet, in which one can find a special spread called the “Diamond shaped spread”, was added to the card deck.

This very thorough spread provides a complete overview of the consultant’s inner life in connection with a specific question. It helps one to set up and shape a healing process. The Psycho-Tarot combines therapeutical techniques such as Gestalt and Transitional Analysis with symbolic imagery and spiritual new age concepts. It rapidly becomes famous in USA and Canada where it is used by many therapists.

The Diamond shaped spread has thirteen components or positions. These positions are linked to the planets and to psychological marks or indicators who show thirteen facets of inner life. The positions are spread out on a table in a diamond shaped pattern.

The number thirteen may have being chosen because there are thirteen cards in each of the four families that make up most card decks. It is also quite possible that thirteen was chosen because of the Mayan calendar and its soul cycle, divided into thirteen parts. His calendar was booming in the “70s”.

The thirteen facets of the “Diamond shaped spread”:

1- Position of the Sun: the center of my world right now.
2- Position of the Moon: the unknown part of the question
3- Position of the Earth: me between what is known and unknown
4-Position of Jupiter: helpful factors
5- Position of Saturn: impeding factors and difficulties
6- Position of Venus: one’s ideal of love and beauty, wealth
7- Position of Mars: challenges, action, will and aggressiveness
8- Position of Mercury: the relieving message and the intuitive solution
9- Position of Neptune: seeing the possible future
10 -Position of Uranus: the changes to make
11- Position of Vesta: what is missing?
12- Position of Pluto: the deep truth within the question
13- Position of the new ascendant: a new start
