Wet 180-grit sandpaper is used to rub the gem. To smooth the surface, firmly rub the gem back and forth across the area of sandpaper that has the water. Turn the diamond over and rub it once more to create another facet. Continue rubbing the diamond to create multiple facets and roughly form it. Finally, polish the stone with a fine polishing paste or liquid to get it into perfect condition.
The goal is to produce a perfectly polished stone with no rough edges remaining. This ensures that the stone will look its best when worn as jewelry.
There are two types of shaping: open work and flat. In open work shaping, the jeweler makes holes in the stone for stringing. Then comes the tricky part: fitting the hole pattern onto the stone. There are many different methods used by jewelers to do this. One method is called "netting," where little nets or grids are placed over the stone to help position each hole correctly. The jeweler then uses these markers as a guide to cut out each hole. Open work can also be done using lasers or computer-controlled machines. Flat stones are shaped without any openings at all. They are usually thicker near the center and thinner on one side. The thicker part is called the body of the stone. It provides weight and helps the stone stay upright when worn as jewelry.
The most basic method is to use polishing powder and a denim cloth. The procedure is straightforward: lay one piece of the material on the cloth and gently rub it over the gem surface. Another simple method is to use soda; in addition to relieving your thirst, it can be used as a polish. Soda can be anything that contains sodium carbonate or bicarbonate, such as baking soda, cream of tartar, or chalk. It's easy to find recipes for homemade cosmetics using only ingredients from around the house.
The best way to keep gemstones looking their best is with regular maintenance. This includes cleaning them regularly with a soft brush or toothbrush and dry cloths. Make sure not to scrub any gemstone too hard, as you want to avoid removing the natural coating of grease and dirt that protects the stone. Some stones are also better kept wrapped in tissue paper or sealed in plastic bags to prevent exposure to moisture which may cause the stone to fade or lose color.
Polishing gems is a great activity to do with your children. They will love seeing all the colors of the stones become brighter after being cleaned off their rough surfaces. There are many different materials you can use to polish gems including toothpaste, baby oil, milk, and salt. Just make sure you don't put anything abrasive in these products or they could damage the gemstones.
Gemologists recommend using a soft brush or toothbrush to clean gems.
Soak the rough gem in the dish of warm water. This process will merely free any dirt, debris, or other items that may have been entangled with the gem. Soak the gem for an hour to an hour and a half. Wipe the gem dry with a soft, nonabrasive cloth. Avoid using abrasive cleansers or soap as this could damage the stone's surface.
If there are specific areas of your gem that are dirty or grimy, use a toothbrush to gently brush away any embedded particles. You can also use a mild cleaner to wash the stone if you prefer; just be sure to rinse it thoroughly after cleaning.
If you want to make your own cleaning solution, mix one part vinegar with three parts water. Use only distilled white vinegar made without additives. Don't use clear vinegar because it contains acetic acid, which is harsh on gems.
Gemologists recommend cleaning your stones before you wear them because the chemicals used to clean them will stain if they get onto your clothing or skin. Cleaning your jewelry while wearing it helps prevent them from getting tangled up in each other.
Cleaning your jewelry is easy if you take the time to do it regularly. As mentioned, soak all items in a bowl of hot water for 30 minutes to an hour depending on their materiality. Make sure not to put any metal items in the washing machine because they might get damaged by the heat.
A faceting machine is used to cut hard jewels. To prepare the gem, use a faceting machine. Because most uncut diamonds are irregular in form, you may need to grind them down. Roughly sanding the gem's edges will get it closer to the size and form you desire. Then polish the stone to bring out its full beauty.
Facets are the visible surfaces of a gemstone. Facetting machines can be manual or automatic. With a manual faceter, one cutter's motion controls all four sides of the diamond. An automatic faceter uses two rotating blades that cut both sides of the stone at the same time. Today's faceters can produce intricate designs within the gemstone's facets.
Facet cutting is an important step in the process of preparing gems for sale. The more facets there are, the higher the quality rating of the stone. One faceted jewel may be more valuable than several uncut stones of the same weight.
Some stones are too soft to be cut by hand. These include soapstone, onyx, and marble. Their smooth surfaces cannot be made rough without damage. They must therefore be cut with a facer.
The best facers have steel knives attached to motors that spin at high speeds. This creates cutting action as the knife slices through the stone. Some facers have multiple knives that work simultaneously to cut many facets quickly.
