Malachite vs Emerald vs Green Onyx: Telling Green Stones Apart
Buying guide
Look at the pattern and how much light passes through. Malachite is opaque, with curved light and dark green bands. Emerald is a transparent green gem you can see into. Green onyx is an even, smooth green with no bands and is often dyed. Malachite is also the softest of the three, so it needs the gentlest care. Our Hive Malachite Bracelet sets a malachite hexagon in 18K yellow gold for AED 3,200 (November 2026).

How to tell them apart at a glance
- Bands mean malachite. Curved stripes in two or more greens, like the rings of a tree, are the clearest sign.
- Depth means emerald. Hold it to the light: an emerald lets light in and often shows tiny natural inclusions inside.
- One flat colour often means onyx. A very even, bright green with no pattern is typical of dyed green onyx.
- Weight helps too. Malachite feels heavy for its size.
If you are buying, ask the seller to name the stone and any treatment in writing.
