Hallmarks are used to guarantee the purity or fineness of gold and silver articles. At Quality Assay, you can trust that you will receive precise hallmarking combined with quality assessment. Hallmarking of gold and silver jewelry has been one of our top services provided to customers for years. We prioritize ensuring the authenticity, purity, and quality of your precious metal items. Through a meticulous process, we provide reliable and recognized hallmarking for gold and silver
Assessment and Evaluation: We carefully assess your gold or silver items to determine their composition, purity, and eligibility for hallmarking.
Precious Metal Analysis: Using the Fire assay method or potentiometric analysis, we accurately determine the metal content and purity of your gold or silver items.
Application of Hallmarks: Once the metal composition is verified, we apply the appropriate hallmarks (HUID) to signify the purity, origin, and other relevant standards using a laser marking machine. These hallmarks serve as a mark of quality and authenticity.
At QualityAssay, we have currently installed a refining capacity of 1000 tons of gold per year. We employ a meticulous and state-of-the-art gold refining process to ensure the highest levels of purity and quality. We hold ourselves to a standard above the norm, aiming for unparalleled quality. Whether you are a jewelry manufacturer, collector, or investor, we are dedicated to helping you unlock the true value of your gold assets.
Assessment and Evaluation: We begin by carefully assessing your gold items, and determining their composition and potential value by using the best available techniques.
Melting and Sampling: Next, we melt the gold to homogenize it and take representative samples for analysis.
Precious Metal Analysis: Our qualified, experienced expert assayers use advanced testing methods to analyze the gold's purity and identify any impurities present.
Refining: Using Aqua-regia processes, we remove impurities to refine the gold to its purest form.
Quality Assurance: Throughout the refining process, we conduct rigorous quality checks to ensure that the refined gold meets the highest industry standards.
Documentation and Reporting: Upon completion, we provide you with detailed documentation and a report, outlining the purity and weight of the refined gold.
Assaying the quality of gold and silver jewelry is not what everyone can do accurately; we are BIS recognized and NABL Accredited laboratory that can carry out this process very professionally.
We are your trusted partner for accurate and reliable assaying of gold and silver. With our laboratory and team of expert assayers, we provide precise analysis and evaluation of your precious metals. Whether you’re a jeweler, investor, or refinery, we are committed to helping you determine the quality and value of your gold and silver assets.
Sample Collection: We begin by collecting samples of your gold or silver items, ensuring that the samples are representative of the entire lot.
Fire Assay: Using the fire assay method, we subject the gold samples to high temperatures to separate the precious metals from impurities. During cupellation, we process the samples by heating in a controlled environment. This process removes base metals and leaves behind the precious metals for analysis. This traditional and reliable method allows us to determine the metal content accurately.
Silver Analysis: Our team of expert assayers utilizes advanced Potentiometric techniques to determine the precise composition and purity of the silver.
Quality Assurance: Throughout the assaying process, we conduct stringent quality checks and adhere to industry standards, ensuring the integrity and accuracy of our results.
Assay Report: Upon completion, we provide you with a detailed assay report, which includes the metal content, purity levels, and any additional information relevant to your specific requirements.
Precision is ingrained in everything we do, from assaying and refining to the minting process. We take pride in producing high-quality investment-grade products. Our meticulous process ensures the creation of exceptional gold coins and casted bars. We transform pure gold into exquisite pieces that embody elegance, artistry, and value.
Master Die Creation: Once the design is finalized by cutomer, we create a master die that serves as the template for minting.
Gold Preparation: We carefully select the highest quality gold for minting. The gold is melted and transformed into the desired form
Minting Process: Using state-of-the-art minting technology, we strike the gold with the master die, transferring the design onto the surface. This process ensures the precise replication of the design and results in stunning minted gold pieces.
Casting of gold: Casting is a technique used to create gold objects by pouring molten gold into a mold or cavity and allowing it to cool and solidify.
Quality Assurance: Throughout the casting & minting process, we conduct stringent quality checks to ensure the integrity, purity, and flawless finish of each gold coin or cast bar with no negative tolerance.
Packaging and Presentation: Once minting is complete, we carefully package each gold piece in protective packaging, ensuring its safety and preservation.
This is a new project which involves recovery of precious metals from jewelry manufacturing waste, buffing dust and other materials related to manufacturing units.
We use the most modern Plasma Technology for recovery. Plasma technology involves the use of ionized gas at extremely high temperatures to dissociate molecules and generate a high-energy plasma state. This plasma state is used to process various materials, including jewelry waste, for precious metal recovery.
This process is faster than other methods and it offers a more environment friendly alternative to traditional smelting methods, as it can reduce harmful emissions and minimize waste generation.
