Tips for Jewelers Who Do

From Alan Revere
The snazziest system
I have seen to find your
chuck key is mounting one of those retractable
spring gadgets that hold a ring of keys on your
belt (sometimes known as a Keyback or key
caddy), under your bench top. Instead of keys,
attach your chuck key. Now it is always
exactly where you left it.
This tip is from 101 Bench Tips

Colored Stones
from Gemstone Cutter
AQUAMARINE
Aquamarine is the blue to greenish-blue variety
of the mineral beryl. It can range from a very
pale blue to fairly intense blue or greenish
blue. Aquamarine is almost always heat
treated, sometimes at the mine site, but
usually after cutting, to drive off the
greenish or yellowish component, leaving a more
pure, and popular, blue hue. This has been
done for so long now that younger buyers often
do not associate the natural greenish-blue
color with aquamarine! However, the unheated
material is always sought after by cutters as
it is highly regarded by gem connoisseurs
and
fine jewelers.
aquamarine, and it is also found in many
locations around the world, including North
material, a rather intense pure blue similar to
after its Brazilian location), has long
disappeared from the marketplace, and the
finest source of high grade aquamarine today
is
Maria Afrique, and the very limited
supply has
doubled in price in the past few months.
Three to ten carat top Brazilian goods range
from $100 to $600 per carat, depending on
intensity of color, while fine cut
Afrique ranges easily to $1000 per carat. No
price differential is seen between heat-treated
and natural gems. Aquamarine, along with
tourmaline and spinel, has become one of the
fastest appreciating gems in terms of cost.
The hardness of aquamarine is usually reported
as 7.5 to 8, but some gems have been
tested and
shown to be less than 7, so some caution is
advised. Aquamarine is not especially brittle,
but heat should be avoided. The stone itself
is not particularly heat sensitive, but it
may
contain invisible liquid-filled inclusions
which, when heated, turn to gas as they expand,
and can shatter a stone. If heated much hotter
than 450 degrees Centigrade, aquamarine is
likely to turn chalky white or colorless. The
ultrasonic is safe if you use caution not to
plunge the stone from room temperature to
boiling. Pickle presents no problems, but the
stone should be allowed to cool first.
The Russians have been successful in creating
synthetic aquamarine. As the price for darker
natural aquamarine continues to skyrocket, we
can expect to see more of this material in
the
marketplace, although the price of the
synthetic keeps it in the luxury synthetic
class. I see prices from $30 per carat for
poorly cut, big-bellied material with windows
to $80 per carat for properly cut,
brilliant
goods in 3-7 carat sizes. The synthetic is
generally very clean and therefore heat
resistant to 700 degrees Centigrade or so, but
you will purify the color at around 500
degrees. So, avoid direct torch, but otherwise
treat it the same as natural.

<=> <=> Tips &
Tricks from
Placing a section of a bamboo skewer in your
flex-shaft can make an excellent wood lap
polishing point. File the protruding end to a
point, and use your favorite rouge. The bamboo
skewers are approximately 3/32 inch in
diameter, which makes them easy to use in a
quick-change handpiece.
Filing the protruding end to a point helps it
to reach into tight places.
Increase the size of your polishing wheels from
the standard 4 inch wheel to a 6 inch
wheel.
This will cut polishing time by over 1/3.
Changing to a 6 inch wheel from an old wheel
worn down to 2 1/2 inch or 3 inch will cut
polishing time to less than 1/2. This is due
to the surface area of the wheels. Although
spinning at the same speed, more surface area
moves over the jewelry in the same amount of
time thereby polishing faster.
Always work just below the center of the buff
wheel while polishing. Never raise the jewelry
above a horizontal line even with the motor
spindle, or lower it too far below. Both of
these situations will cause the wheel to grab
the item from your hand.
Work should be pressed firmly against the
wheels while polishing, so that you feel the
cutting action. However, never press so hard
that the motor slows down. Excessive pressure
will not give a better polish or polish
faster.
A firm even pressure throughout the operation
is preferred.

It is difficult to explain
surface textures to
a customer who is not familiar with the
terminology of the trade. Prepare a texture
strip by taking a strip of metal and apply
different textures in 10mm sections along the
strip. You will be able
to show the surfaces
to clients and prevent misunderstandings.

Proper Take-In Procedures Help Everyone!
Many ring mandrels measure ring
sizes
differently than the ring sizers used to
measure the customers finger, resulting in an
improperly sized ring.
One method to avoid this
problem is to purchase
several sets of plastic ring sizers. Take
apart the sets of sizers and organize them by
finger size in a plastic compartment box with a
snap close lid. Then
measure the customers*
finger with these sizers and place the correct
ring sizer in the job envelope with the ring to
be sized. Then the
bench jeweler will have no
questions as to the size to make the ring.
When finished, return the ring
sizer to the
tray for future use.

Workshop Safety Tips From
To escape unnecessary work,
look for examples
of people who have solved the same kinds of
safety problems you have to solve, and see if
you can adapt some of their ideas and
approaches for your own small shop. Look for
models around you.
You want to aim for a well laid
out, orderly
workshop, electrically and fire safe, with low
dust and few solvent procedures; excellent
local ventilation at the appropriate work
stations; the use of work clothing cleaned
frequently, lots of personal safety equipment
(earmuffs,
safety glasses etc.), different
heights to work at over the work day and a
conscious attitude about workshop safety.
Choose procedures that do not
involve exposure
to risks. Set things
up so that you can not
hurt yourself. Mark
Twain said *If you do not
lie you do not have to remember anything*. We
could crudely paraphrase that to *If you do not
have an unsafe workshop you have less to worry
about*. Make safety a
habit and then it will
not seem like work.
