Andranondambo Sapphire Discovery

  The story

 

Sapphire from Maromby in a métamorphic limestone. ( Andranondambo area.)
                      Looking for sapphire on the ground in 1992.
Sapphires from Andranondambo, discovered in 1991.       ( South-East of Madagascar )

In 1658, Flacourt, the governor of Fort-Dauphin mentions

sapphires in the south of Madagascar, and he was drowned
on his voyage home on the 10th of June 1660.
In 1808, Barthélemy Hugon writes that in the valley of
Ambolo there is a so beautiful stone and so rare that
lapidaries have not  been able to recognize it and it was
above of all that is not diamond. ... In 1991, at the time of
the great dryness in the south, sapphire samples are given
at the day, several centuries after their first discovery. The
son of Mrs. Dauphine, innkeeper in Tranomaro, main village
of the valley, was among  the prospectors.
Actually, one of the most beautiful quality in the world is
just leaving ground.

  The area of Tranomaro is characterized by an extreme
  calcic and magnesian paragneiss abundance: gneiss with
  diopside, plagioclasites, pyroxenites, wernerites, 
  wolastonites, cipolins, with varied léptinites, generally with
  garnet, kinzingites, quarzites. One finds there rather
  frequently gneisses syenitic or lamboanites.
  Gneisses of injection are very frequent. The typomorphic
  minerals are: basic diopside, scapolite, calcite, plagioclases,
  wollastonite, garnet, cordierite and corundum.
 
 

The sapphires on the left comes from Ambandanira, and that on right-hand side from Maromby (area of Andranondambo.)

SANDSTONES OF ISALO.
The white sandstones of Isalo present imposing stratifications
intersected with gravel beds and small conglomerates.

ruiniform relief because the presence of braces silicious
veins.
The mineral-bearing deposits include : a deposit of generally
classified gravels, the richest part and larger elements
being at the base of the bed - rock.

Polychromatic sapphires from Iankaroka discovered in 1990. The far-south of Madagascar, semi-desert, does not present
any asphalt road yet, dust and trepidations are the daily
lot of any traveller. Sunsets and the natural life of its
inhabitants  offer an appreciable compensation.

Sapphire from Analafady ( Ambondromifehy ) North.         

                                      

The alluvial deposit of Ambondromifehy is exploited since
1996.  It is located in a Jurassic limestone, but the origin of
sapphires is in alkaline basalts from the close volcanic zone.
