While "pink amethyst" itself typically refers to a specific variety of amethyst with a pinkish hue, trade professionals might use terms like "light pink amethyst" or "pale pink amethyst" to specify a lighter shade within the pink spectrum.

The lavender color in amethyst is primarily attributed to trace amounts of iron impurities within the crystal lattice of quartz. The presence of iron ions can create variations in color, and in the case of amethyst, it contributes to the purple or lavender hues.

Amethyst is a quartz variety alongside rose, clear, smoky quartz and citrine.
