When assessing a rose gold piece, look for '14K,' '14KT,' or '585' stamped on the metal, the same purity marks used on yellow and white gold, confirming the gold content regardless of color.
Myth & Meaning
The medieval tradition connecting St. Valentine to an amethyst ring carved with the image of Cupid is a specific attribution. That specificity gave amethyst a romantic symbolic layer directly tied to its February placement, distinct from the sobriety and piety associations it carried in ecclesiastical contexts and complementary to its birthstone designation for the month.
Elemental Detail
Rose gold's pink hue comes from copper in the alloy, with the specific tone determined by proportion. More copper produces a deeper rose, less produces a softer blush, which is why rose gold pieces can vary in warmth.
