Citrine vs. "Citrine Calcite": What's the Difference?

Here's a piece of buyer education worth having before you shop: not everything sold as "citrine" is actually citrine. True citrine is a variety of quartz (SiO₂) colored yellow to golden-orange by trace iron, and natural, untreated citrine is genuinely rare — most citrine on the market, even legitimately labeled, is heat-treated amethyst, which turns a similar golden color when heated to the right temperature.

What we carry and label as citrine calcite is a different mineral altogether: a caramel-colored variety of calcite (CaCO₃), sharing citrine's warm golden tone but none of its quartz chemistry or hardness. This is a well-established naming convention in the mineral trade — the color resemblance is close enough that "citrine calcite" has become the accepted way to describe it, but it's worth knowing you're getting a softer, different mineral at a more accessible price point, not quartz-family citrine.

Practically, this matters most for jewelry: citrine calcite, like all calcite, sits at a Mohs hardness of just 3 and needs gentler handling than true citrine's 7. For display pieces, collections, and crafting, that difference matters far less — and citrine calcite's warm, caramel color is genuinely lovely on its own terms.
