Incoming precious metals are purchased in one of two ways: 

Small quantities: We complete a visual grading and touch stone acid test

  • Visual Grading: Smaller quantities of material can be purchased by identifying a mark (i.e. 18K, 14K, 10K, Sterling.)  A stone acid test is then used to verify the mark.
  • Touch Stone Acid Test: The item being tested is scratched across a stone. A standard (known) karat is scratched alongside, and then acid is used to compare the reation time it takes to disappear.

Larger quantities: Large volumes of gold and silver are purchased on a melt and assay basis.

  1. The first step is to take an incoming weight on the material.
  2. Then we melt the gold with flux to separate the metal from non-metallics.
  3. Bar is cleaned and weighed.
  4. From this bar a sample is taken and assayed to give us the precise gold, palladium, silver, and in some cases a platinum content.
  5. Once the assay is complete, and the bar is ready to be purchased, the value is settled on a forward market.
