PRECIOUS METALS
A precious metal is a rare metal of high economic value. Gold,
silver, platinum and palladium are the most common precious
metals.
SILVER
Fine silver (99.9%) is generally too soft for the production of
jewellery; therefore silver is usually alloyed (mixed) with other
metals to improve its strength . Sterling silver is the most widely
used silver alloy which contains at least 925/1000 fine silver.
GOLD
24 K gold is very soft and therefore alloyed with another metal to
be used for the production of jewellery. This process alters the
fineness, hardness, melting point and colour of the gold. Copper is
the most widely used alloy metal and lends jewellery a reddish
tone.
Spinning Jewelry:
• We produce jewellery in Sterling silver and silver with 14 K
gold. We produce gold jewellery in 8, 9 or 10 K gold.
• 8 K gold is an alloy with at least 333/1000 pure gold.
• 9 K gold is an alloy with at least 375/1000 pure gold.
• 10 K gold is an alloy with at least 417/1000 pure gold.
• 14 K gold is an alloy with at least 585/1000 pure gold.
GOLD PLATING & SILVER
PLATING
Gold and silver plating are methods used to deposit a thin layer
of gold or silver on the surface of the jewellery.
RHODIUM PLATING
Our diamond series consists of silver rings with 0.25 micron
rhodium plating. The rhodium plating is electroplated onto the
surface of the silver to make it more reflective and white. A
rhodium plated surface also brings out the diamond's beauty and
hardens the silver's surface.
Spinning Jewelry:
• Our silver jewellery is silver plated with fine silver (99.9%
silver), except for our oxidized products.
• Our gold plating is 14 K.
• The gold, silver or rhodium plating will wear off in time,
depending on the use and treatment of the jewellery.
ENAMEL
Cold enamelling consists of a chemical powder mixed with a liquid
which is then applied to the jewellery with a brush. Heating is
applied to harden the enamel.
Spinning Jewelry:
• All products with enamel is made with cold enamelling.
• Cold enamelling is more shock-absorbing than ordinary glass
enamel and does not crack as easily if the jewellery is
dropped.
PEARLS
Pearls are produced in live molluscs as a defence against an
irritant inside the shell. The mollusc forms a pearl by depositing
mother-of-pearl around the irritant.
There are two types of pearls: natural pearls and cultured pearls.
Natural pearls are created spontaneously in nature without any
human intervention. They are rare and therefore very
valuable.
Cultured pearls are produced artificially with the help of humans
who insert shell beads in the mollusc. Cultured pearls are often
produced in freshwater (freshwater pearls) and are available in
many colours, shapes and sizes.
Spinning Jewelry:
• All our pearls are freshwater pearls, often in white, cream and
rose.
STONES AND GEMS
A precious stone or a semiprecious stone is a piece of attractive,
rare mineral which, when cut and polished, is used for jewellery.
Diamonds, rubies, sapphires and emerald are always precious stones
while other stones with less hardness and lustre are called
semiprecious stones.
Diamond
It is the hardest, naturally occurring mineral known to us. The
diamond's ability to scatter white light into its individual
component parts (spectral colours) makes it a desirable gem. A
diamond is graded based on the four C's: carat, clarity, colour and
cut.
• Carat is the diamond's mass (1 carat = 0.20g)
• Clarity regards the inclusions of a diamond. The number, size,
colour, position, orientation and visibility of the inclusions
affect the clarity of the diamond and hence its value. FL+IF:
Pure/flawless, VVS: Very very small inclusions, VS: Very small
inclusions, SI: Small inclusions, PK: Visible inclusions.
• The colours of "white" diamonds are graded using letters and
names, from D, which is the best and colourless diamond, to K,
where the colour of the stone is whitish.
• The cut of diamonds is important to bring out the characteristic
"fire" and brilliance for which diamonds are known. A brilliant is
a round diamond cut with 58 facets. A full cut diamond is the same
as a brilliant.
Synthetic stones
Today, most stones can be created synthetically in a laboratory.
Synthetic stones are not imitations. A synthetic or natural stone
has the same characteristics but the synthetic stones often have
clearer colours and no inclusions.
Most cubic zirconia (cz) are synthetic produced. The cubic
zirconia copies the diamond's appearance and colour but does not
have the same chemical or physical properties (often, its hardness
is reduced). Cubic zirconia is produced in many different
colours.
Spinning Jewelry:
• We use diamonds, zircons, synthetic stones, glass stones and
semiprecious stones.
• Our diamond series includes: Carat: 0.03ct. Clarity: SI = small
inclusions Colour: H - I, H = Wesselton (white), I = Top Crystal
(slightly tinted white) Cut: Full cut
• Our diamonds have been certified by our supplier as non-conflict
diamonds.
TARNISH
8 K gold and silver react in contact with air, perfumes, soaps,
etc. They tarnish which is a natural process. Tarnished silver has
a grey or black layer. When used regularly, the jewellery is
"polished" to produce a fine patina. Tarnished jewellery is not to
be confused with oxidised jewellery which has been given a dark
coating.
Spinning Jewelry:
• All our jewellery is given an anti-tarnish coating to prevent
rapid tarnishing of the jewellery.
• The coating will wear off in time, depending on the use and
treatment of the jewellery.
MAINTENANCE:
• All our silver products can be polished and cleaned using
ultrasound.
• Products without pearls, enamel and coloured stone may be
immersed in a silver dip;
however, there is a risk of discoloration.
• Do not polish gold plated products. They may be cleaned using
ultrasound.
• We do not recommend immersing gold plated products in silver
dip.
• Our 8 K gold products can be polished and cleaned using
ultrasound.
