Pounamu, also known as New Zealand greenstone, is valued for its cultural significance, durability, and natural beauty. Because authentic pounamu is highly sought after, imitation stones and other types of jade are sometimes sold as genuine greenstone.
If you are unsure whether a piece is real, there are several characteristics that can help you identify authentic pounamu. These include the stone’s weight, texture, colour depth, and hardness. While some tests can help you recognize genuine greenstone, the best confirmation often comes from understanding where the stone comes from and who carved it.
This guide explains practical ways to identify real pounamu and avoid common imitations.

Pounamu refers to a group of hard, durable stones traditionally found in the South Island of New Zealand. Most commonly it refers to nephrite jade, although related stones such as bowenite are also considered pounamu in Māori tradition.
Authentic pounamu forms naturally under intense pressure over millions of years. This process gives the stone its distinctive strength, smooth texture, and subtle variations in colour. Shades can range from deep green and olive to lighter translucent tones depending on the type of stone.
Because of its cultural importance, pounamu is treated as a taonga in Māori culture and is often carved into meaningful designs such as the koru, toki, and pikorua.
Several stones are commonly mistaken for pounamu. Some are natural minerals, while others are manufactured materials made to imitate jade.
Common look-alikes include:
These stones can sometimes appear similar at first glance, especially when polished. However, they often lack the density, strength, and natural depth of colour that genuine pounamu has.
Understanding the differences between these materials is one of the easiest ways to avoid buying imitation pieces.
Although laboratory testing is the only way to guarantee authenticity, there are several practical observations that can help you identify genuine pounamu.
Real pounamu is dense and slightly heavier than many stones of similar size. When you hold a genuine piece, it often feels solid and substantial rather than light or hollow.
Imitation stones made from glass or resin are typically lighter and lack this natural density.
When polished, authentic pounamu has a very smooth, almost silky surface. However, the stone still retains a subtle natural texture beneath the polish.
Synthetic materials often feel overly glossy or glass-like, without the depth and natural variation seen in real greenstone.
Genuine pounamu usually shows depth within the stone. Colours may appear layered or slightly cloudy when viewed in natural light.
Common shades include:
These variations reflect the natural mineral structure of the stone.
Pounamu is extremely tough and resistant to scratching. Historically it was used for tools and weapons because of its durability.
While you should never attempt to scratch a finished carving, genuine pounamu is significantly harder than most imitation materials.
Real pounamu often feels cool to the touch when first picked up. Because the stone is dense, it retains cool temperatures longer than glass or resin imitations.
After being worn for a while, the stone gradually warms to body temperature.
| Feature | Real Pounamu | Fake or Imitation |
|---|---|---|
| Weight | Dense and solid for its size | Often lighter |
| Surface | Smooth with natural texture | Very glossy or glass-like |
| Colour | Deep green with natural variation | Flat or overly bright colour |
| Hardness | Extremely tough and durable | Scratches more easily |
| Temperature | Feels cool when first touched | Warms quickly |
One of the most reliable ways to ensure authenticity is to purchase pounamu from trusted sources. Reputable carvers and galleries usually provide information about where the stone was sourced and who created the carving.
Many visitors choose to buy directly from workshops or galleries in regions where pounamu carving has a long history, such as the West Coast of the South Island.

Yes. Some imitation stones can look very similar to real greenstone, which is why buying from reputable sources is important.
No. Pounamu is extremely tough and resistant to scratching compared to many other stones.
Pounamu carvings carry symbolic meanings rooted in Māori culture and tradition. Over time, the meaning of a carving often grows through the experiences of the person who wears it.
Yes, pounamu can be worn by anyone. Traditionally it is often gifted rather than bought for oneself, as a sign of respect and connection.
No. Pounamu usually refers to nephrite jade found in New Zealand, although related stones such as bowenite may also be considered pounamu.
The terms pounamu, jade, and greenstone are often used interchangeably, but they do not all mean the same thing. Understanding the differences helps avoid confusion and ensures pounamu is recognised in its correct cultural and geological context.
