Lapidary means do to with stones. Craftspeople who create carvings and designs out of stones are called lapidaries. They cut, form and polish stones that are employed in jewelery, sculptures and other ornamental art works. Diamond cutters do not come under this title as their work is highly specialized.
Specialized lapidaries work in commercial stores and they create original pieces for their customers. But now lapidary is becoming favored for the beginners who enjoy it as a pastime and finish up spending many hours making jewelery and other pieces.
Lapideries use many hand tools which include saws, sanders and chisels to make their pieces. One specialized form is inlaying marble and gemstones.
The Medici Chapel in Florence has many inlaid hardstones. In China they are skilled in jade that has been continuing since the Shang dynasty.
There are three kinds of lapidary strategies:
2. Cabochon cutting
Pretty much all lapidary work is done using machines. But the older techniques are way more well liked by folks who are doing it for a hobby.
Bonded grind wheels of silicon carbide and a diamond tipped saw are used. Diamonds can not be cut with this system as they're really hard, they need the specialized diamond tools.
Another meaning of the word lapidary is of inscriptions. These are scribblings that are chiseled into stone. This needs a particularly experienced person to be ready to produce the crisp and correct style of condensed writing.
Lapidary is only used with stones that can be polished. The most common is Quartz. There are plenty of kinds of quartz, for example: Amethyst, citrine, topaz, agate, tiger eye which get their names from their hits.
The main process is shaping the stone with a grinding wheel or disc and then regrinding to get the glossy surface. The polishing is done with different types of mineral oxides.
Tumbling is the method given to erratically formed stones, what this does is with a tumbling machine it repeatedly perturbs the stones with a succession of coarse to fine grits and water. These stones are inexpensive and are used to make easy jewelry and other novel items like key rings.
For the beginner they should find out how to cut and polish a cabochon (cabs for short). These are gems that have flat backs and rounded tops. They can be any shape round, square and oblong.
Stones that are colored, clear, or patterned with fascinating patterns are usually cut as cabochons. Colored or clear stones are typically faceted. These are typified by the flat polished surfaces prepared in a way letting the light shine through the polished surfaces and back to the spectator in hundreds of twinkling lights.
The reflections might be colored or white. The rainbow affect is due to the light being split up into the colored parts in the stone.
This is just an introduction to lapidary and it's an extraordinarily interesting subject and there's lots to learn.
