Smelted Citrine
Smelted Citrine is glass (gem-look furnace product), (amber-tinted glass). In the hand, it rates 5 to 5.5 on the Mohs scale, and it runs uniform honey amber and golden orange. A big, perfectly clear, evenly golden 'citrine' tower at a bargain price, no color zoning, no inclusions, but round gas bubbles and swirl lines inside reveal furnace glass.
The geology.
Smelted Citrine carries the formula (amber-tinted glass). It belongs to the amorphous (none) system. On paper it is glass (gem-look furnace product).
It sits at 5 to 5.5 on the Mohs scale. The surface reads vitreous, glassy-bright. Light behaviour is transparent, eerily flawless. Specific gravity runs 2.4 to 2.6. The streak is white. It breaks with conchoidal fracture.
A big, perfectly clear, evenly golden 'citrine' tower at a bargain price, no color zoning, no inclusions, but round gas bubbles and swirl lines inside reveal furnace glass.
Expect to see it as large polished towers, points, spheres or freeforms.
The origins.
Furnace product, largely from Chinese glass workshops, sold at gem shows and online as 'citrine'.
On value, the database notes: worth glass prices only.
Traditional associations.
In energy work traditions, glass towers are considered empty imitations of citrine's sunny abundance reputation.
Recorded here because it is part of how this material is sold, not because it is a property of the material.
Spotting the real thing.
A big, perfectly clear, evenly golden 'citrine' tower at a bargain price, no color zoning, no inclusions, but round gas bubbles and swirl lines inside reveal furnace glass.
This IS the fake: flawless golden towers and spheres with interior bubbles are tinted glass, cross-check Smelted Quartz and Heat-Treated Citrine for the full citrine deception map.
| Looks like | How to tell them apart |
|---|---|
| Natural citrine | Natural citrine is pale, often smoky-tinged, with subtle zoning, and large clean pieces are genuinely expensive |
| Heat-treated citrine (baked amethyst) | Baked amethyst is at least real quartz, white frosty bases and ember-orange tips on cluster points |
| Smelted quartz (clear) | Same furnace product without the amber tint, both share bubbles and bargain pricing |
At-home tests.
None of these need a lab. A 10x loupe, good daylight and a steady hand cover most of what a buyer needs to know about smelted citrine.
| Test | What you should see |
|---|---|
| Loupe | round bubbles and flow swirls = glass, every time |
| Polariscope | glass stays dark on rotation; quartz blinks light-dark |
| By touch | Glass feels warmer and lighter than quartz and chips glassy-bright |
Anything that scratches, burns or dissolves the piece is a lab job. Get it appraised rather than testing it apart.
Care & handling.
At 5 to 5.5 on the Mohs scale it handles careful wear but scratches against quartz and dust. Store it separately and take rings off before rough work.
It breaks with conchoidal fracture, which is worth knowing before you set it or drop it.
Warm water and a soft cloth clean almost everything. Ultrasonic tanks, steamers and household cleaners are where pieces get ruined.

The physical record
The formula on record is (amber-tinted glass). Crystal system: Amorphous (none). Specific gravity: 2.4 to 2.6. Streak: White. Cleavage and fracture: Conchoidal fracture.
How it reaches the market

What it gets confused with
Natural citrine: Natural citrine is pale, often smoky-tinged, with subtle zoning, and large clean pieces are genuinely expensive. Heat-treated citrine (baked amethyst): Baked amethyst is at least real quartz, white frosty bases and ember-orange tips on cluster points. Smelted quartz (clear): Same furnace product without the amber tint, both share bubbles and bargain pricing.
What it is worth
Worth glass prices only.

One more thing
The economics are the tell: genuine citrine this large and clean would cost hundreds, glass towers sell for the price of a sandwich because melting sand is cheap.
