Gold Assaying Basics

If you are buying, selling, or refining gold, you're going to want to be sure you're getting full value. One way to do this is by assaying, or in other words, evaluating, the gold. This is something often done by a precious metals refinery, like Jewelers Refining Group. The basic process has been around for hundreds of years but has evolved over time. The following are the main ways gold is assayed today:
  1. Fire - This method is the oldest and most accurate, and also the most preferred. First, the gold is melted and a sample is taken and weighed. The sample is placed in a special crucible called a cupel. The cupel absorbs all non-precious metals and what remains is then hammered flat, rolled thin and heated in a porcelain crucible. A weak nitric acid solution is added, which removes any silver. The gold is rinsed with distilled water and dried. What remains is 99.999 percent pure gold. This sample is weighed. The weight of the original sample is divided by the weight of the pure sample and the result is the assay.
  2. Inductively Coupled Plasma Optical Emissions Spectroscopy (ICP-OES) - Solid samples are dissolved, mixed with water and fed into plasma. The plasma will emit light on a particular wavelength indicating gold. The light is recorded and calibrated against specific standards. This provides a quantitative analysis.
  3. X-Ray Fluorescence (XRF) - This is similar to ICP-OES but can be done on samples that are solid, liquid, or powdered. The sample is irradiated with x-rays and the individual component wavelengths of the fluorescent emissions are measured by the spectrometer.
There are also methods you can use at home with ingredients you probably have on hand. For instance, to detect gold-filled items (gold plated vs. copper), simply etch a small scratch and apply nitric acid. The copper will react and bubble green. While these methods work, it's important to always get an assay performed by a professional, qualified company.

Integrating Old Stones into New Jewelry



Stone Removal | JRGInc.com
Integrating old stones into new jewelry is a fantastic way to recycle out-of-date or broken pieces. Gems set in family-heirloom pieces can also be reset on their own or with a combination of new stones to create stunning pieces of considerable value. Safe stone removal is an essential part of this process, and jewelers interested in using old stones need to learn how to remove them from all types of settings.

Harvesting stones from traditional settings in gold and silver jewelry is usually a simple mechanical process, but removing stones from platinum and cluster settings can be tricky and may require chemical assistance. Removing extremely small stones can take a lot of time, so focusing on larger stones for removal and resetting is a good practice. Once the stones are out, the fun begins. From here, you can mix and match sizes, shapes and stones to create one-of-a-kind pieces.

Creating new jewelry out of old stones is a rewarding process that keeps good gemstones from gathering dust in an attic. Whether you buy older jewelry to recombine on your own or you have customers who want to give their older pieces new life, this process takes skill and a good eye for design. The first step is safe stone removal, so learn the basic manual skills required, purchase the proper tools and keep up with changes and advances in chemical processes.

Palladium Refining for You



Along with investing in stocks and mutual funds, you may prefer to build your portfolio by investing in metals. Metals prove to be a solid asset that can give you a lucrative return as long as you take certain steps to ensure your investment. Because the amount of money you can receive may depend on the quality of the metals, you would do well to consider partnering with a palladium refining company that knows from what objects metal can be gleaned and how this metal can be refined to the highest quality. These safeguards can help you achieve the highest return and also let you build a portfolio that will secure your future.

You may be like many other investors and assume that metals can only be refined from pieces of jewelry, coins, and other similar objects. However, as you learn more about this kind of investment, you will learn that other objects, such as aircraft parts and circuit boards, are also valuable sources for such metals. When you expand your knowledge, you can choose what companies to invest with and also use this information to grow your own portfolio. This information also can ensure that the metals in which you have invested have future use and can be made into objects like jewelry, watches, and other consumables that will have a high resale value.

Investing in refinable metals can be a wise decision, and the best way to get the most out of this investment is by knowing how to maximize your returns. Here are some tips that will help you get more out of your hard-earned money when you choose to include these metals in your investment portfolio.

  • Metals can be retrieved from some unlikely sources. While most people think of jewelry pieces as a source of valuable metals like gold and silver, circuit boards, semiconductors and out-of-use aircraft parts can also be refined in order to retrieve these valuable resources.
  • Choose a refining group that has a reputation for recovering as much of the precious metal as possible from a refinable metal. Jewelry pieces like necklaces, bracelets and earrings may contain metals that can be of value, and retrieving these items requires a combination of skill and specialized equipment that Jewelers Refining Group, Inc. can provide.
  • Working with an experienced refining group allows jewelry makers to ensure that the recovered metals can be used in the process of creating beautiful pieces. In this instance, the return on the investment of the scrap metal or jewelry is higher due to the improved price that can be expected in relation to selling the jewelry piece.

The Benefits of Precious Metal Refining

If you are interested in taking your jewelry manufacturing business to the next level and are intent on producing eminently durable pieces that will thrill your customers, you should surely consider contracting with a precious metal refining service. Gold, silver, palladium and platinum are the metallic focal points of most bracelets, rings and necklaces. Professional refining processes can boost the durability and aesthetic appearance of these metals, which will make them more valuable on the open market.

Refining companies typically specialize in saving precious metals from heading to the regional trash heap. Professionals can separate metals from old circuit boards, auto catalysts and other electronic scrap items. The small amounts of gold and silver are then recycled and used again within the industry. Because there is a fairly limited supply of precious metals, refining allows the elements to stay in circulation so that customers can enjoy them in jewelry pieces of all styles and textures.

Armed with the precious metals you need to craft lovely items, you can begin putting your skills to work. Diamonds, sapphires, rubies and emeralds can be affixed to metallic matrices. You might even choose to manufacture special lockets that customers can wear around the neck as keepsake items. A specialized precious metal refining service will give you the tools you need to expand in the field going forward into the future.
