La Belle De Jouris an in-natura emerald matrix, a mineral specimen exquisitely encrusted with rough emeralds formations, with metal scents such as molybdenite incursions, granitoid gneiss and quartz on Schist, surrounded with natural emerald crystals that travel inwards, making it a remarkable work of art by nature. It was found to contain traces of several metals such as gold, chromium, tungsten, aluminum, zinc, nickel, etc. Truly a one-of-a-kind matrix!
The specimen was unearthed during a sunny day in Serra da CarnaiÌba, in the province of Bahia, Brazil. After more than an estimated **0 million years (Precambrian era) this beautiful large specimen of black schist containing 9 large emerald crystals clusters, green beryl and small amounts of molybdenite was extracted from a depth of over **0 ft. (~**0m). It was then baptized as La Belle De Jour due to it being the most beautiful piece ever seen, immediately admired by everyone that laid their eyes on her. It was purchased by EMPROGEO LLC in March ***8, and imported into the United States on March *7th, finding in Miami Florida its new temporary home.
Its
former home Serra
da CarnaiÌba is
a Precambrian emerald
deposit site, found in a typical geologic setting
with Archean basement
and supracrustal, ultramafic, granitoid and rocks.
Volcano- sedimentary series occur as imbricated
structures or as bodies affected by complex folding and
deformation. Emerald mineralization belongs to the
classic biotite-schist deposit, which formed by the
reaction of pegmatitic veins within ultrabasic rocks
(G. Giuliani, L. J.H.D. Silva and P. Couto).
This region is famous for basically only two
other findings of such rare formations, being it
the (in)famous Bahia Emerald evaluated as much as
**5M USD, and
most recently an unnamed matrix evaluated in **0M
Brazilian Reais (~**1M USD).
Please note that the dimensions given are approx.
both in imperial and metric system. Following
definitions are helpful to understand the
technical descriptions made in this report.
Matrix: In geology, the material
in which something is embedded, either the
natural rock that holds crystals, fossils,
pebbles, mineral veins, and the like.
Schist: Megascopically
crystalline rock that has a highly developed
schistosity, or tendency to split into layers.
Banding (foliation) is typically poorly developed
or absent. Most schists are composed largely of
platy minerals such as muscovite, chlorite, talc,
sericite, biotite, and graphite; feldspar and
quartz. The specimen in this report is described
as a black schist due to its high black mineral
content, most probably biotite (iron rich
brown-black mica) and other dark colored
minerals.
Prismatic: Mineral crystals that
display a uniform cross-section.
Euhedral: A fully formed mineral
crystal.
Anhedral: A mineral crystal with
no external faces.
Emerald: Green variety of
minerals species beryl (Be3Al2(Si6O*8) containing
trace amount of chromium (Cr) and/or vanadium
(Va) as cause of color.
Green Beryl:Another green
variety of beryl containing iron (Fe) only as
cause of color. It is much more commonly found in
nature, green to slightly yellowish green, and
lacks the bright bluish green tone of emerald.
The Specimen is a large black matrix containing prismatic non-terminated emerald crystals, massive green beryl and anhedral molybdenite crystals. The specimen measures approx. *0" (~*0.8cm) x *4.5" (~*6.8cm) x *5" (~*8.1cm) overall, and *4 (~**7cm) at its longest circumference. It weighs a solid **6 lbs. (~**6.2kg). The size of large emerald crystals ranging from 6.5" (~*6.5cm) to 2"(~5cm) length, and widths varying from 2.5" (~6.3cm) to 1" (~2.5cm).
Crystal No. 1: A few intergrown prismatic
emerald crystals with green beryl base and black matrix
inclusions, none displays termination. Approx. measurements
are 4" (~*0.2cm) x 2.5 (~6.4cm). The luster is glassy with
some crystal faces showing growth lines.
Crystal No.2: Prismatic emerald crystals are
intergrown within a larger anhedral green beryl, largest one
is approx. 2.*5" (~7cm) x 1" (~2.5cm). No termination is
observed. The cluster is next to a few anhedral molybdenite
inclusions.
Crystal No.3: A cluster of prismatic emerald
crystals measuring approx. 6.5" (~*6.5cm) x 1.5" (~3.8cm) is
next to a smaller anhedral emerald approx. 1" (~2.5cm) in
diameter. This piece is entirely opaque with an obvious color
zoning at the top. The right side of the crystal cluster
displays a more distinct prismatic crystal face compared to
the rest.
Crystal No.4: Three emerald crystals grown
together with green beryl. The cluster measures approx. 4"
(~*0.1cm) x 2" (~5cm).
Crystal No.5: Three grown together opaque
crystals displaying color zoning, measuring approx. 2.*5"
(~7cm) x 1"(~2.5cm).
Crystal No.6: Opaque, intergrown with green
beryl at the base where it's attached to the matrix. It
measures around 5"(~*2.7cm) x 2" (~5cm) and is covered by
very small, l*2mm long, needle-like black crystals at the
top. The crystal displays a break and natural healing
structure in the middle.
Crystal No.7: This larger opaque crystal
displays the least luster of all with lower saturation of
green. It measures around 3.*5" (~9.5cm) x 1.5" (~3.8mm).
Crystal No.8: This smaller single crystal
attached to a green beryl base displays the best color
and
the luster of all. Linear growth lines on the crystal
surfaces parallel to c-axis are visible. It measures 1"
(~2.5cm) x 0.*5" (~1.9cm).
Crystal No.9: Two parallel grown opaque to
translucent crystals displaying color zoning with some
black, small, needle-like crystals as inclusions at some
surfaces. The top crystal measures 3.5" (~8.9cm) x 2" (~5cm)
and the lower one 3.*5" (~9.5cm) x 1.*5" (~3.2cm).
A remarkable Specimen. Such rarity is extremely coveted by private collectors, museums, universities, etc. There will never be another specimen equal to ; perhaps another one—though equal—will only be unearthed the next **0 million years. Who knows? -One thing we do know: whoever acquires this beauty of nature, will acquire along with it a piece of time, a piece of wonder, a piece of Earths history, that will leave anyone mesmerized by it!
