SHOP TIPS BY CECIL

• If your tumbler drum starts slipping, wrap the shaft

with soft electrician's tape.

• The polishing pads are getting ripped up through

improper use. Remember that you should be polishing

your stones on the right hand side as the pad is turning

downwards (clockwise). Make sure any pointed stone

is polished with the point down to avoid ripping the

pad or hurting yourself. There's nothing more

frustrating than getting your stone to the polish stage

and then having it flip out of your hands and breaking

on the floor.

Rock of the Month

EPIDOTE

Epidote, while not

general known for

exceptional crystals

can produce some

magnificent

specimens. Its

unique green color

which is often described as "pistachio", is quite striking in

well colored specimens. In fact, sometimes it is called

"pistacite". The name epidote may come form the Greek

epidosis, meaning increase, referring to the fact that one

side of its crystal is longer than the other. When rotated,

translucent prisms of epidote display strong dichroism - the

colour is dark green in one direction and brown in another.

Here's some more information if you are going on The Four

Brothers Mountain Field Trip (see side bar for field trip

information). Gary Richards will be bring in some samples

of Epidote to the March 24th meeting.

PHYSICAL CHARACTERISTICS

• Color is "pistachio" green to yellowish or brownish green,

also brown to black.

• Luster is vitreous.

• Transparency crystals are transparent to translucent.

• Crystal System monoclinic; 2/m

• Crystal Habits include long, somewhat prismatic or

tabular crystals with a typically dominant pinacoid that the

crystal is often flattened against. The terminations are

wedge shaped or tapered pyramids. Many clusters show

grooved slender crystals or acicular sprays. Also massive,

fibrous or granular.

• Cleavage good in one direction lengthwise.

• Fracture is uneven to conchoidal. • Streak white to gray

• Hardness is 6-7 • Specific Gravity is 3.3-3.5

• Associated Minerals calcite, biotite, hornblende,

actinolite, andradite garnet and other metamorphic

minerals.

• Other Characteristics: striated to the depth of grooves in

some crystals.

• Notable Occurrences Untersulzbachtal, Austria; Italy;

Baja, Mexico and many localities in the USA.

• Best Field Indicators only one direction of cleavage,

crystal habit, color and hardness.

• Chemistry: Ca2(Al, Fe)3(SiO4)3(OH), Calcium

Aluminum Iron Silicate Hydroxide.

• Class: Silicates • Subclass: Sorosilicates • Group: Epidote

• Uses: mineral specimens and rarely as a gemstone.

THE SCIENCE

Epidote is a structurally complex mineral having both

single silicate tetrahedrons, SiO4, and double silicate

tetrahedrons, Si2O7. The formula of epidote could be

expressed in a such a way so as to reflect this organization;

Ca2(Al, Fe)Al2O(SiO4)(Si2O7)(OH). The two aluminums

represent the parallel chains of AlO6 and AlO4(OH)2

octahedra that are the heart of the epidote structure. The

silicate groups and extra ions connect the chains together.

Since the chains are parallel, the crystals tend to be

prismatic. The chains are arranged in parallel planes and

the perfect cleavage breaks the bonds between these planes.

BC GEM SHOW

April 1st, 2nd & 3rd, 2005

To celebrate the 50th anniversary of the British

Columbia Lapidary Society the BC Gem Show is

featuring Jade, the official gemstone of the Province.

There will be many displays of the creations of B.C.

artists that work with jade. Deborah Wilson of Vernon

will be displaying some of her very imaginative carvings

as well as demonstrating jade carving.

Deborah Wilson teaching at a workshop

As always, there will be a great variety of displays of

gemstones, crystals and minerals from member clubs.

Many cases will contain collections of hand-crafted

jewelry and silversmithing.

Throughout the show, members will be demonstrating

techniques of lapidary, sculpting, faceting, silversmithing,

flint knapping, wire wrapping, and enameling. The gold

panning is a very popular demonstration.

Among the many features of this, Canada's largest gem

show, will be 30 dealers carrying supplies for the hobby

along with specimens of crystals, minerals, cut stones,

cutting material and many gift items.
