01Decisive
Look for flattened disc-shaped spangles
Pressing flattens trapped bubbles into bright circular discs lying roughly parallel. Natural amber's bubbles are spherical or irregular and randomly oriented. Parallel discs are close to conclusive.

How to Identify Pressed Amber
Real amber powder fused under heat and pressure. Genuine material, but not a natural piece.
The Baltic coast, the Dominican Republic, Myanmar, Mexico2 references
Pressed amber, historically called ambroid, is made by heating small fragments and offcuts of genuine amber under pressure until they fuse into a single mass, which can then be cut and polished. Everything in it is amber, so it floats in brine, smells sweet under a hot pin and takes a static charge — every quick test comes back positive.
The give-away is internal structure. Pressing draws the trapped air out into flattened discs, so the bubbles become the characteristic 'sun spangle' — a bright circular disc rather than a sphere, often several of them lying roughly parallel. Natural amber's bubbles are round or irregular and randomly oriented.
The second sign is flow structure. Where fragments merged, pressed amber often shows faint swirls, a slightly marbled or mottled quality, and occasional hairline boundaries between one fragment and the next. Held to a strong light and turned slowly, it looks assembled, because it was.

Ambroid · Reconstructed amber
Establish which of these you are holding before judging it. A genuine piece read against another reference's rules will look wrong when it is not.
Model-specific checks
What decides a Pressed Amber
These apply to this model and not to the rest of Amber. Work them alongside the maker's general checks, not instead of them.
02Strong
Turn it in strong light and look for merge lines
Faint swirls, a marbled quality, or hairline boundaries where one fragment met another indicate a pressed mass. Natural amber shows flow layering from resin that ran in stages, which is smoother and more continuous.
The market
What a Pressed Amber does on the secondary market
Well below natural amber. Legitimate when disclosed and common in inexpensive bead strands.
