The color of the spinels
The spinelis available in many faces, the best known and most coveted being its vibrant red. Philippe Tournaire appreciates the intensity and the sparkle of a rosé red spinel, which allows you to enhance a harmony of colors and make it even more festive. Some are therefore of a magic red, others are orange red or an intense rosé red and their hot tones are largely due to the presence of chrome. The more this chemical element is present when the formation of the spinelle, the more its color will be sparkling. In colder tones, this gem can be blue, purple and purple, even going to bluish green.

We discovered that in reality, it is the combination of iron and cobalt that allows our admiring eyes to contemplate the intense Blues of these spinels, mainly from Madagascar, Pakistan and Sri Lanka. The spinelle, a gem still too little known to the general public, knows how to be enigmatic by having different colors depending on the light which lights it (daylight or electric light) and can also be star, at 4 or 6 branches.

These gems have been synthesized since the beginning of the 20th century. It is possible to unmask a false blue spinel by looking at its inclusions and testing it with gemology instruments. The real blue spinels contain iron and cobalt while the false does not have any trace of iron, which can help to distinguish them. There are also triplets, composed of two parts in colorless synthetic spinel, gathered by a thin layer of colored glass. By looking at this profile substitute, we can generally distinguish the 3 different layers.

- Timour's "ruby":An exceptional spine of 361 carats cut in cabochon belonging to date to Queen Elisabeth in England. On this incredible gem is engraved with Persian inscriptions, thus testifying to its seniority.
- The origin of the word spinelle is debated:It could come from the Greek "Spita" meaning "sparkle" or from the Latin "spina" which means "thorn". The two origins could respectively refer to the fire, the bright red color of a spinel and the specific crystals which are clean. The red spinel would be a symbol of power and courage. The blue spinel would allow the one who brings him to push negative energies.
