Lapidary Crafting and Jewelry Making

There are a few different possibilities; I'd suggest the GIA courses to learn gemmology. There are also specialized diamond cutting courses available. Talk to your friendly local gem and mineral club to find out if they offer courses or know who does. Most lapidaries are self taught; if you understand how different grits of sandpaper are used to smooth wood, going from coarse to fine, you can pretty much figure out how to cut and polish minerals on your own using diamond machinery.

Indeed, they can. In Japan, clam shells are a commonly used as kiln furniture to allow the heat (and ash) to circulate below a pot.

The marking 585 means it is 585/1000 percent gold or 14k/24k, it is 14k. It is used in Europe commonly.

an jweller can resize the ring by expanding it or contrasting it.you can increase its size by heating it and can be made smaller by making it cold

Yes, provided that they have a plater and the proper knowledge and skills to do it properly.

This is typically a gem polishing problem and can have varying fixes. Read up on the particular stone and change your polishing method; eg. you may have to switch from aluminum oxide on canvas to fine diamond on a hardwood wheel, or you may have to pay closer attention to heat. A more specific question will enable a more specific answer.

Water glass, or sodium silicate, is a white powder that is dissolved in water to form an adhesive. I'd suggest following the instructions on the package. Ensure that the stone to be dopped is clean and free of oil, as is the dop, and ensure that both surfaces are flat.

There must be a ways to place a Smaller diamond under the larger diamond, may be they must be using same setting or 2 different settings, but there is no specific setting for placing smaller under larger diamond. If any one come across the name of such setting please let me know.

If it is proper jeweler's rouge, it is composed of ferric oxide and wax or grease. It should melt with a low to moderate amount of heat.

Yes because they can learn more about his/her job. (Mostly this event happens in Eroupe)

In actual fact,there is no such thing as 'white' or 'green' jewelers rouge.Proper jewelers rouge is red,the 'rouge' is french for red,it should always be red.The 'white' and 'green' compounds on the market are much coarser abrasives,nowhere near as fine as proper red jewelers rouge,and not really recommended for polishing soft metals such as gold,silver,chrome etc.

If repeated washing with soap and water doesn't do the trick, I'd put everything into a sealable box or bag and dump in a whole pile of baking soda, leave it alone for a week. It that doesn't work, try peroxide. If that doesn't work, there are a ton of commercial products available, but little info on their efficacy; eg. Nature's Miracle, Diaper Pure, Urine-Off. Personally, if the supplies didn't cost that much, I'd just chuck 'em.

Opal, Agate, Petrified Wood, Jasper, fossil bone.

Now for the real Answer.......Which one of the five would last the longest to win the old reward of lasting some 300,000,000 plus years,

Solder is manufactured in hundreds of different grades and compositions for thousands of different applications.

Solder that might be described as "Silver solder" is most commonly commercially manufactured in about 50 different compositions with silver contents of up to 40% and is priced accordingly.

Silver solder is often used in jewellery making and repair, engineering and many electrical manufacturing processes.

Missouri has produced some fabulous minerals from underground lead-zinc mines, but these are pretty much closed at the moment. I'd suggest joining a local gem and mineral club, or consulting the local geology department at a museum or university. Or buy "The Common Rocks and Minerals of Missouri " by WD Keller.

I've never heard of a "Surveyor Lapidary", do you perhaps mean Surveyor, or Lapidary??? The two terms have no connection.

60 is the dimension for the diameter of ring. I just bought one with a diameter 59 DAU is the surname of the designer who makes jewellery. He works from Berlin, Germany

If the line is constant then it is probably a hardware problem that requires repair. If the line changes or goes away when you change the screen resolution for the desktop then you can probably fix the problem through software.

Precious metal clay is a material that has gold or silver particles embedded in a highly pliable binder that is crafted and fired just like clay.

The hardest gemstone is the diamond.

I've been seeing "french pearl" listings on Ebay recently and, being a veteran at this, my best guess is that it's a way of saying it's a fake (i.e. "faux") pearl.

You can purchase hard tempered silver wire for these types of applications. However, if you wish to work harden soft wire, first shape it into the desired configuration and then lightly hammer the wire while turning it to ensure even application of force. Continue to do this for a few moments and you will find that the wire hardens due to the stress placed on the material. The more you bend, hammer and shape wire the harder it will get. It will eventually reach a breaking point where it becomes brittle and can snap so don't take it too far!
