1.  Platinum Solders are numbered in 100 number increments from 1000 to 1700.  This number stands for:

A.  Their melting temperature in Celsius.

 

Traditional Platinum solders are numbered from 1000 to 1700 in 100 number increments representative of their melting temperature in Celsius, IE: 1700 solder melts at 1700 degrees Celsius, 1600 solder melts at 1600 degrees Celsius, 1500 solder melts at 1500 degrees Celsius, etc.

 

The newer Plumb Platinum Solders do not use this temperature distinction but list the platinum content.  900 solder contains 900 parts platinum and 100 parts alloy, 925 solder contains 925 parts platinum and 75 parts alloy, and 950 solder contains 950 parts platinum and 50 parts alloy.  Their melting temperatures vary by manufacture.

2. 24 Karat White Gold is

D.  Impossible to make.

 

Karats are used to determine the purity of the gold.  24 Karat gold is pure gold.  18 Karat Gold is 18 parts gold by weight and 6 parts alloy by weight.  14 Karat Gold is 14 parts gold by weight and 10 parts alloy by weight.  Gold in its pure state is a yellow metal therefore all 24 Karat gold must be yellow gold.  To make white gold either nickel or palladium is added to the alloy to bleach the gold white.  All white golds must have some alloy in it to make it white and cannot be 24 Karat.

 

 

 

3. When sizing rings the difference in one ring size is:

D.  2.54 millimeters

 

The difference in one size is 1/10 of an inch or 2.54 millimeters which is rounded off to 2.5 millimeters for general usage in the jewelry shop.  To size a ring down you need to remove 2.5 millimeters for each size you need to go down.  To size a ring up you need to add 2.5 millimeters for each size you need to go up.

4. When setting Diamonds you need to be careful of:

B. Chipping the stone, they are fragile.

 

Diamonds are the hardest substance known to man and cannot be scratched.  However, they are a fragile substance and can be chipped.  A comparison can be made to fine china dishes.  A china plate is hard and is not scratched by a fork and knife or other utensils.  However, if you drop the china plate on a hard tile floor the plate will shatter.

 

Although diamonds are not as fragile as many colored stones jewelers encounter, care must be exercised while setting diamonds to keep from chipping them.  Particular attention must be made to thin girdles and any pointed ends such as found on pear, marquise, baguette, and princess cut diamonds.
