In amethyst, vivid, evenly distributed purple is the goal. The finest 'Siberian' quality shows deep purple with red and blue flashes. Avoid stones with visible color zoning (bands of lighter/darker purple), brownish tones, or grayish undertones. Because amethyst is affordable, you can afford to be very selective about color. Clarity should be eye-clean — included amethyst is rarely worth buying given the abundance of clean material. Large sizes are available without dramatic price increases, so don't settle for a small, mediocre stone when a large, fine one is within budget.
Buying Smart with Amethyst
Since amethyst is abundant and affordable, your buying strategy should focus on maximizing beauty rather than minimizing cost. Go for the largest, most vivid stone you can find for your jewelry design. Custom cutting (concave faceting, fantasy cuts) can elevate amethyst from 'nice' to 'spectacular' for modest additional cost. Consider buying rough or pre-formed stones and having them custom cut — amethyst rough is very inexpensive. For jewelry, step cuts (emerald cut) and mixed cuts showcase amethyst's color beautifully. Use GemstoneAI to evaluate color quality across your options.
