Synthetic Turquoise
Synthetic Turquoise is lab-grown / composite imitation. In the hand, it rates 2.5 to 5 on the Mohs scale, and it runs uniform sky blue and teal with painted-on black webbing. Very affordable; worthless as gem turquoise. The Gilson lab that conquered opal also built turquoise, but chemists note it contains no actual turquoise mineral, making it technically an imitation.
The geology.
Synthetic Turquoise carries the formula Varies, ceramic micro-spheres, dyed resin, or turquoise powder in epoxy. It belongs to the none (massive composite) system. Its listing category is lab-grown / composite imitation.
It sits at 2.5 to 5 on the Mohs scale. The surface reads waxy to dull plastic. Light behaviour is opaque. Specific gravity runs 1.6 to 2.7. The streak is white to pale blue. It breaks with granular to conchoidal fracture.
Perfectly even robin's-egg color at a bargain price, under magnification Gilson-type material shows a cream-colored 'wheat flour' texture of tiny spheres, and block material shows dye concentrated in fractures.
It turns up mostly as beads, cabochons, carvings, heishi strands or inlay.
The origins.
Factory product; Gilson ceramic version dates to 1972, resin block material dominates today's bead market.
On value, the database notes: very affordable; worthless as gem turquoise.
Traditional associations.
In energy work traditions, imitation turquoise is regarded as a decorative substitute without the protective reputation of the genuine stone.
This is lore, and we label it as lore. The measurable facts are further up the page.
Spotting the real thing.
Perfectly even robin's-egg color at a bargain price, under magnification Gilson-type material shows a cream-colored 'wheat flour' texture of tiny spheres, and block material shows dye concentrated in fractures.
This IS the fake: most sub-$1-per-bead 'turquoise' is block resin or magnesite composite; painted-on uniform black webbing is the classic tell.
| Looks like | How to tell them apart |
|---|---|
| Natural turquoise | Natural stone shows color zoning, matrix that runs through the stone, and a real price tag |
| Dyed howlite | Howlite shows gray spidery veins and a white interior when scratched, it is a different fake of the same target |
| Variscite | Variscite is naturally greener with fine web and is a genuine mineral |
At-home tests.
A loupe and a window seat settle most questions about synthetic turquoise. No workshop required.
| Test | What you should see |
|---|---|
| Solvent swab | Acetone swab in a hidden spot lifts dye from block/resin material |
| Hot needle on a back surface | plastic smell = resin composite |
| Loupe | spherical cream micro-texture (Gilson) or webbing that sits only on the surface |
If these checks leave you unsure, that is what appraisers are for. Do not file, heat or soak a piece to find out.
Care & handling.
At 2.5 to 5 on the Mohs scale this is a soft material. Keep it as a display piece, store it apart from harder stones, and skip daily-wear settings.
It breaks with granular to conchoidal fracture, which is worth knowing before you set it or drop it.
Most damage happens during cleaning, not wearing. Avoid steamers, ultrasonic tanks and anything from under the sink.

The physical record
The formula on record is Varies, ceramic micro-spheres, dyed resin, or turquoise powder in epoxy. Crystal system: None (massive composite). Specific gravity: 1.6 to 2.7. Streak: White to pale blue. Cleavage and fracture: Granular to conchoidal fracture.
How it reaches the market
Factory product; Gilson ceramic version dates to 1972, resin block material dominates today's bead market.
What it gets confused with
Natural turquoise: Natural stone shows color zoning, matrix that runs through the stone, and a real price tag. Dyed howlite: Howlite shows gray spidery veins and a white interior when scratched, it is a different fake of the same target. Variscite: Variscite is naturally greener with fine web and is a genuine mineral.
What it is worth
Very affordable; worthless as gem turquoise.
Where buyers get caught
This IS the fake: most sub-$1-per-bead 'turquoise' is block resin or magnesite composite; painted-on uniform black webbing is the classic tell.
One more thing
The Gilson lab that conquered opal also built turquoise, but chemists note it contains no actual turquoise mineral, making it technically an imitation rather than a true synthetic.
