Gem Profile- Smoky Quartz

by Dale Armstrong
When macrocrystalline quartz is colored or tinted in shades of gray or brown, it is called smoky quartz. These gray shades can be very pale through grayed yellow-brown with or without reddish tints, dark charcoal colored or nearly black and almost opaque.
Smoky quartz commonly forms in vugs within pegmatite veins.

It appears in masses or color-zoned crystals that sometimes grade toward amethyst or citrine.

These crystals range from thin druzy crusts to giants weighing nearly half a ton.

You can also find smoky quartz near water-clear quartz or amethyst, or inside geodes.

The smoky coloration comes from inclusions of aluminum, calcium, lithium, or magnesium.

Natural radiation contributes to the color too.

Many "black" stones on the market are artificially irradiated smoky quartz.

In Scotland, rich caramel yellowish-brown smoky quartz carries the title "cairngorm."

It has been mined in the Cairngorm Mountains and serves as Scotland's national stone.

Early Scots wore cairngorm jewelry as a form of money, since they avoided carrying coins.

It also created Scottish "pebble" jewelry, a mosaic of precious metal and native stones.

Naturally black, almost opaque smoky quartz is called "morion."

Dark, lustrous smoky quartz from Switzerland is known as "Alpine."

In Brazil, smoky quartz mixes with citrine.

The smoky quartz often turns yellow when heated during formation, like ametrine.

Sometimes, the original smoky crystal stays smoky, while yellow quartz over it creates a phantom.

Marketing names for smoky quartz imitate its color, like whiskey quartz.

Natural whiskey quartz resembles Scottish cairngorm, but affordable pieces are often heat-treated to cherry wood color.

Root beer quartz looks like a brown beer bottle.

"Smoky topaz" is not legal, since topaz and quartz differ.

The mix-up arose from smoky quartz found near topaz in Scotland.

Topaz costs more and is softer, while smoky quartz stays affordable, durable, and beautiful.
