What we do

At Hartza Refining, we offer a range of services to meet the specific needs of our clients. Our services include mobile refining, smelting, and assaying of precious metals, as well as gemological testing and diamond grading services. One of our unique services is the inspection of seller's goods for buyers who are not on the ground. We understand that it can be challenging for buyers to verify the quality and quantity of precious metals, especially when they are not able to visit the seller's location in person. That's why we offer an inspection service to provide our clients with peace of mind when purchasing precious metals remotely. Our team of experts can visit the seller's location and conduct a thorough inspection of the goods, ensuring that they meet the buyer's specifications.
