ZAMBIA'S
MINERAL
WEALTH
For many years now Zambia has been an important source of gemstones
to the worlds jewellery market. Perhaps best known for its fine
emerald and amethyst, Zambia also produces an extraordinary variety
of gems such as garnet, tourmaline, citrine, malachite, agate,
aquamarine, heliodor and many other beryls.
These minerals are mostly exported in the rough form since there are
very few cutting (lapidary) operations in the country.
Gemstone export procedures have been streamlined in recent years to
allow foreign buyers easy access to the market. The Ministry of
Mines in Lusaka will assist with whatever paperwork may be needed
for the trouble free export of gems.
Locally crafted gemstones and jewellery is developing and some fine
examples of this art can be found in the capital. Jagoda
gems cuts and manufactures its own jewellery in
gold and silver. The owners are registered valuation officers with the
Ministry and their retail outlet offers an exquisite range of mineral
specimens and cut gems from all over Zambia.

AQUAMARINE
 |
Deep
blue or Double blue is rarely found in large clean pieces anywhere
in the world. Continuous production of such colour is un-heard of,
which keeps Zambian production in great demand. Lighter shades of
this gem can be found in other countries (Nigeria, India) but popularity
is growing for the deep blue green variety presently found in the
Katete / Petauke area for its beautiful natural sea blue / green
hue. Zambian double blue is still readily sold overseas as 'Santa
Maria L'Afrique' conjuring a mystique over its source. Prices for
such gems have been known to reach over $ 800 per carat! |
Brazil
- (1950'sSanta Maria discovery) A suite of some + 1000 carats was
given to HRH Elizabeth 11 and now forms a priceless necklace & tiara
worn rarely on state functions. Mozambique - (early 90's) Called
Santa Maria L'Afrique for its resemblance to the original discovery |
|
EMERALD
 |
Zambian
emerald although discovered in the late 40's was not commercially
mined until the 1950's. Today Zambia is one of the world's leading
producers of fine Emerald. Highly prized for its intense colour
and remarkable clarity, Zambian Emerald retains its magnificent
hue even in small stones of less than 0.5 ct. Although the experienced
professional could identify a Zambian emerald in a Bond Street window,
the chances are that it will be sold as a 'Sandawana' stone since
the exporting of Zambian rough has long been considered a clandestine
event and therefore does not lend itself well the respectability
projected by the top jewellery shops of the world. The trade uses
much legend, lore and illusion when it comes to selling a fine emerald.
Antiquity now seems to be the order of the day. Some dealers refer
to emeralds as "Old Mine and offer wonderfully supportive tales
as to how the stone found its way through the centuries. Although
much research has been done to establish the source of the 'Old
Mine' (believed to have been in India) it still remains a mystery.
This does not appear to deter the buyer and 'Old Mine' stones have
been known to change hands for as much as US$ 30,000 per carat. |
Colombia,
much sought after for the large crystals and therefore bigger stones.
However the material does not suit small stones and invariably is
more included than its Zambian brother.Zimbabwe: Sandwana mine is
well known for its similarity to Zambian material. Steady production
from this mine has been bolstered by Zambia's illegal exports, rendering
an even greater reputation as a reliable source.Brazil, Madagascar,
Mozambique, Russia. Nigeria also produces an 'Emerald' coloured
by vanadium but it is not intentionally recognised as emerald since
the chromium content is too low. |
|
GROSSULAR |
The
green variety of grossular garnet, discovered a few decades ago
by Scottish geologist Cambell Bridges in Kenya near the Tsavo National
Park, is also known as Tsavorite. It is normally verdant or dark
green in colour similar to that of fine green Tourmalines but sometimes
is even comparable in colour to Emerald. Little known by the general
public, it is in demand by collectors and connoisseurs. Fine quality
stones are extremely rare in Zambia. But lighter greens have been
found in Mkushi and Eastern province. |
|
|
TOURMALINE(comes
in many colours)
 |
Tourmaline
has become probably the best selling 'semi-precious' in recent years.
This may partly be due to Paloma Picasso's signature range for Tiffany
a few years ago. The enormous variety of colours in which Tourmaline
is available was surely a major inspiration for this talented designer.
Some of the colours in the group have been give special names such
as the red I pink variety known as Rubelite or blue which is known
as Indicolite and brown /cognac as Dravite. Green Tourmaline comes
in a wide range of shades but the rare Emerald green variety is
popularly known as Chrome Tourmaline, which relates to the traces
of Chromium, which give this its unique colour. Zambia has been
mining Tourmalines for many years - the most famous mine being Hofmeyer
Mine near Nyimba. Production there has dropped in recent years but
occasionally some fine greens and deep reds are recovered by local
diggers at this now abandoned mine. The pink deposits from near
Mkushi offer some of the best rubelite we have ever seen in this
country and new deposits are constantly being found all over the
Eastern Province. Indicolite has been seen but is often mistaken
for blue Sapphire by the local dealers whose disappointment is quite
obvious at point of sale! |
Brazil
has been a major producer of Tourmaline for decades and tales of
great suffering rewarded by fabulous finds have resounded through
the gem trade for many years. Of late however production has dropped
due to the exhaustion of some of the most prolific mines. In the
early 90's and extraordinary discovery of bright blue and green
tourmaline from Paraiba to the gem by storm. Production was slight
and most stones recovered weighed less than one gram. Such frenzy
ensued to purchase sizeable pieces that in Tuscon's Gem Fair in
'92 one +5 ct stone of 'electric / neon 'blue changed hands for
a staggering US$8,000 per ct! Namibia has also been a source of
fine Tourmalines but again production has dwindled in recent years.
Madagascar and Mozambique also have fine Tourmaline deposits. But
with the sapphire and Emerald finds in recent years attention has
switched to these more rare, more precious stone mines. |
|
HELIODOR
 |
Heliodor
or yellow beryl is far more common than its brothers Aquamarine
or emerald. The pegmatite occurrence in the Eastern Province of
Zambia has produced some very fine crystals good size and colour.
It is not uncommon to hear of the practice of heat treatments to
heliodor in order to change the colour from yellow to blue. This
is also possible with green beryl since the two contain three molecules
of Iron (Fe+++) and by simple heating to around 400 F the third
molecule is released and instantly the colour changes to blue. This
is a completely irreversible reaction and the 'new' colour will
be as stable as any normal Aquamarine. |
Mozambique,
Brazil, Madagascar, Russia, Zimbabwe, India, and Namibia. |
|
GREEN
BERYL |
This
green coloured beryl does not have a special name. Sometimes the
fine line between Aquamarine and green beryl can lead to much confusion.
However Green beryl contains the same possibilities for heat treatment
as heliodor and is more often treated to resemble its Blue cousin.

GARNET GROUP
|
PYROPE |
The
fiery red member of the family can sometimes be very bright due
to small quantities of Chrome in the crystal structure. Although
large quantities of Pyrope are found in Zambia only some have the
intensity of colour we demand for our jewellery. Eastern Province
& Mazabuka. |

Mexico, USA, Argentina, Brazil, and Australia. |

Lanka, Tanzania, Zimbabwe |
|
SPESSARTITE |
Named
after the Spessart region of Bavaria, Germany where it was originally
mined. It has become very popular in recent years and is produced
in quantity in Namibia and sold under the trade name 'Mandarin Garnet'
Occurs around Lundazi. |
Namibia,
Madagascar, Mexico |
|
CORUNDUM FAMILY |
SAPPHIRES |
Sapphires
monopolise the corundum group since they can be found in almost
any colour or hue. However when a sapphire is red in colour it is
called a Ruby. Ruby today is the most expensive of all the four
commercial 'precious' stone group. (Diamonds, Emeralds, Sapphire,
and Ruby) However it is worth noting that almost all Sapphires and
Rubies will these days be subjected to heat treatment to enhance
their colour and /or clarity. Natural stones are in high demand
by collectors; therefore it follows that few untreated stones are
ever available to the average buyer or jewellery maker. Quality
Sapphires are not mined in Zambia but some material for cabochons
occasionally can be found near the Zambezi Escarpment. |
Madagascar
and Tanzania have recently started producing fine stones to compete
with the more established sources such as Sri Lanka, Thailand, Kashmir
and Burma. A natural fine Burmese Ruby of + 8cts would easily command
a price at auction today of over $100,000 per ct. |
Warning!
Tourists are likely to be approached by unscrupulous dealers who will
offer a variety of cut and rough stones, the majority of which are not
all they appear to be. It is illegal to buy from unregistered sources
and the law will not protect you if you are cheated - caveat emptor!
Places to be wary of include the road to Siavonga (near Kariba border
post) where you can find poor quality pieces of amethyst from an abandoned
mine. Authorities do not turn a blind eye to the unauthorised purchase
of these, therefore beware of attempting to export without the proper
paperwork.
A
startling range of coloured glass pebbles in polythene bags will also
greet you from the side of the road together with many other wild life
products e.g. live chickens, tortoise shells and snake skins!
Car parks
and markets in the city are favourite places for unscrupulous dealers
since they can disappear very quickly in the ensuing commotion. The
more sophisticated groups may use hotel bars and generally appear as
well dressed businessmen.
Small parcels of terminated Quartz crystals
have been known to pass hands as Zairean diamonds! Another famous con
is the sealed green bottle of ‘emeralds’ normally marked
"Emerald Grade A, sealed for export - not to be opened in the Republic
of Zambia". So far all of these have proved to be Quartz crystals
painted with a vivid green epoxy resin. Moulded brass ingots stamped
"Angolan Gold" often appear alongside silver and gold plated
trinkets in the streets.
