Copper and silver in calibrated proportions produce the warm yellow tone in 10kt yellow gold, with zinc sometimes added to improve workability. The alloy mix is doing more aesthetic work than most people realize.
Stone Story
Gemological grading has a tendency to name its benchmarks after places. For amethyst, it is critiqued by "Siberian" quality. Stones of this caliber showcase deep, evenly distributed purple with rose-red flashes. This grade of stone was found in Russia's Ural Mountains and has remained the reference point for fine amethyst color ever since, regardless of where the stone actually came from.
