Garnet

Garnet is not one mineral but a family of related minerals that share the same crystal structure. The red ones most people know are almandine and pyrope, and the purplish red mix of the two called rhodolite. Spessartine is orange. Grossular comes in many colours, including green tsavorite and orange hessonite. Andradite includes demantoid, a green garnet with more fire than diamond. Garnets are almost never treated. Gem garnets are not grown in labs for jewellery; the lab-made YAG and GGG have a garnet structure but are diamond imitations, not garnet gems.

Natural garnet vs lab crystals and imitations

Mined and lab-grown garnet are the same mineral; this is what differs

What it isA natural garnet: almandine, pyrope, rhodolite, spessartine, grossular or andraditeLab-grown crystals with a garnet structure, made as diamond imitations
ColourDeep red, purplish red, orange, green and moreUsually colourless; sometimes coloured
Tell-tale signNatural ; dark red stones can look almost black in large sizesVery clean and heavy; sold under its own name
PriceFrom a few dollars a carat for red garnet to hundreds or thousands a carat for fine tsavorite and demantoidLow
How it is listedNames the type (rhodolite, Mozambique, tsavorite) and the sizeRare in jewellery today; named YAG or GGG

Red garnet is cheap enough that most garnet jewellery is real garnet. The traps are in the names: bead listings called "garnet red jade" are dyed stone, not garnet. The other trap is the cheap "certified 100 ct tsavorite" or "demantoid" from sellers with no reviews: fine tsavorite and demantoid are rare and cost hundreds of dollars a carat or more, so a huge one for $30 is not what it says.

Treatments. Garnets are almost never treated: what you see is the natural colour. The main thing to watch for is dyed lookalike beads, and historically, garnet-and-glass doublets used to imitate other gems. Garnet is hard enough for most jewellery but can chip; clean it with warm soapy water. Demantoid is softer and is best kept out of ultrasonic cleaners. All gem treatments explained.

  • Garnet: Middle Urals, Russia. The classic demantoid source, found in the 1800s and used by Fabergé. Position approximate.
  • Garnet: Garnet Ridge, Navajo Nation, Arizona, USA. Red pyrope garnets brought up in volcanic rock, sometimes called anthill garnets. Position approximate.
  • Garnet: Bohemian Central Highlands, Czech Republic. Source of the small deep red pyropes known as Bohemian garnet. Position approximate.

  • Garnet: Kunene Region, Namibia. Where bright orange mandarin spessartine was found in the 1990s. Position approximate.

How it is cut

Lab garnet is mostly machine-cut in calibrated sizes, which is why a cut lab stone costs little more than its rough. Fine mined stones are often native-cut to keep weight, then recut by precision cutters. See cuts from easiest to hardest and whether cutting your own is cheaper than buying cut.

In short

Garnet grows over millions of years in the earth, or in hours to months in a lab. Both are real garnet; the mined stone is rare and priced for rarity, the lab stone is priced for the cost of growing it. Buy lab to wear and enjoy, check the listing names the mineral, and test it when it arrives.

Frequently Asked Questions

Is garnet one mineral?

No. Garnet is a group of minerals with the same crystal structure but different chemistry. The main gem kinds are almandine, pyrope, rhodolite, spessartine, grossular (including tsavorite and hessonite) and andradite (including demantoid).

Are garnets always red?

No. Garnets come in almost every colour: orange spessartine, green tsavorite and demantoid, yellow and orange grossular, and rare colour-change and blue garnets.

Is there lab-grown garnet?

Not for jewellery in any real amount. YAG and GGG are lab-grown crystals with a garnet structure, but they were made to imitate diamond, not to copy garnet gems.

Are garnets treated?

Almost never. Garnet colour is natural. Watch instead for dyed stones sold with names like "garnet red jade".

What is the rarest garnet?

Fine demantoid and fine tsavorite are among the rarest and most expensive. Demantoid is famous for its fire, which is higher than diamond.

What is Bohemian garnet?

Small, deep red pyrope garnets from the Czech Republic, set close together in jewellery that was hugely popular in the 1800s.
