The various names and attributes assigned to the philosopher's stone have led to long-standing speculation on its composition and source. Exoteric candidates have been found in metals, plants, rocks, chemical compounds, and bodily products such as hair, urine, and eggs.
The three phases of the magnum opus: nigredo, albedo and rubedo. (from Pretiosissimum Donum Dei, published by Georges Aurach in 1475). Rubedo is a Latin word meaning "redness" that was adopted by alchemists to define the fourth and final major stage in their magnum opus. [1]
In alchemy, the Magnum Opus or Great Work is a term for the process of working with the prima materia to create the philosopher's stone. It has been used to describe personal and spiritual transmutation in the Hermetic tradition , attached to laboratory processes and chemical color changes, used as a model for the individuation process, and as ...
The philosopher's stone of European alchemists can be compared to the Grand Elixir of Immortality sought by Chinese alchemists. In the hermetic view, these two goals were not unconnected, and the philosopher's stone was often equated with the universal panacea; therefore, the two traditions may have had more in common than initially appears.

[7] After the 18th century alkahest was taken less seriously over time.
In alchemy and philosophy, prima materia, materia prima or first matter (for a philosophical exposition refer to: Prime Matter), is the ubiquitous starting material required for the alchemical magnum opus and the creation of the philosopher's stone. It is the primitive formless base of all matter similar to chaos, the quintessence or aether.
In European alchemical tradition, the elixir of life is closely related to the creation of the philosopher's stone. According to legend, certain alchemists have gained a reputation as creators of the elixir. These include Nicolas Flamel and St. Germain. A work by Michael Scot speaks of gold as an elixir of life.

The tradition remains today with the name of the element mercury, where chemists decided the planetary name was preferable to common names like "quicksilver", and in a few archaic terms such as lunar caustic (silver nitrate) and saturnism (lead poisoning).
