Green Natural Stone Slabs

This page brings together every green stone on our site: marble, onyx and quartzite slabs, and a small number of large marble tiles.

Green marble ranges in name from Light Green Extra and Aqua Green to Forest Green and Verde Levanto. Calacatta Verde and Calacatta Green are named for their green veining. Green onyx, such as Jade Green Onyx, Light Green Onyx and Green Lagoon Onyx, lets light through and is often chosen for backlit panels and bar fronts. Green quartzite, such as Emerald, Tiffany and Verde Fantastico, is a natural stone that is harder than marble and reacts less to acids. Several quartzites here are listed in a leathered finish, which has a soft texture rather than a mirror shine.

Green stone varies a great deal from one block to the next, even under the same name. That is why each slab has its own page and photographs.

For a shorter list of marble slabs with a green base colour, see Green marble slabs. For all onyx, including the paler and warmer tones, see All onyx. For tiles in every colour, see Large marble tiles.

Some Frequently Asked Questions About Green Natural Stone Slabs

What minerals make green natural stone green?

Green in natural stone comes from several different minerals depending on the stone type. In serpentinite — which includes many stones sold as 'green marble' like Verde Guatemala and Verde Alpi — the colour comes from serpentine group minerals (antigorite, lizardite, chrysotile). These are hydrated magnesium silicates where iron substituting for magnesium in the crystal lattice produces the green colour. In true green marble, the colour typically comes from chlorite (a magnesium-iron-aluminium silicate) or epidote dispersed through the calcite matrix. In green quartzite, minerals like fuchsite (a chromium-bearing mica) create vivid emerald tones. In green onyx, copper compounds in the depositing groundwater produce the colour. Each green stone has fundamentally different chemistry, which is why the shades range from pale sage to deep forest.

Are all green marbles actually marble?

No — and this is one of the most important distinctions in the stone industry. Many commercial 'green marbles' are actually serpentinites. Serpentinite is a metamorphic rock formed from the alteration of peridotite (a rock from the earth's mantle) by hot water — a process called serpentinisation. It is composed of serpentine minerals, not calcite. This matters practically: serpentinite does not react to acids the way calcite marble does, but it can be sensitive to moisture-related expansion and may contain veins of softer minerals like talc. Verde Guatemala (from Guatemala and India), Verde Alpi (from Italy), and many other green stones are serpentinites. True green calcite marble — where the green colour comes from chlorite inclusions in a calcite matrix — is rarer. We specify the geological identity of every green stone we sell.

Is green stone suitable for kitchen worktops?

It depends on the specific stone. Green quartzite (like Emerald Green or Fusion Green) is excellent for kitchens — Mohs 7, acid-resistant, very hard-wearing. Green serpentinite (like Verde Guatemala) is moderately hard and does not etch from acids, but it can be vulnerable to thermal shock and may develop hairline cracks over time if exposed to extreme temperature changes — placing a very hot pan directly on the surface is not recommended. Green calcite marble behaves like any marble — needs sealing, reacts to acids, suits kitchens with attentive care. Green onyx is too soft and delicate for kitchen worktops. For a green kitchen worktop with minimal maintenance concerns, green quartzite is the safest choice.

Where does green natural stone come from?

Green stones come from all over the world, reflecting the global distribution of the geological processes that create them. India's Rajasthan region produces several green serpentinites and quartzites, including Rainforest Green. Guatemala is the source of Verde Guatemala, one of the most widely used green serpentinites. Italy produces Verde Alpi from the Alpine ophiolite belt and Verde Issoire from Liguria. Brazil is the primary source of green quartzites like Emerald Green and exotic varieties like Amazzonite. Iran produces green onyx from cave and spring deposits. Pakistan produces Green Onyx from Balochistan. The geological processes that create green stone — serpentinisation, chlorite formation, copper deposition — occur at tectonic plate boundaries worldwide, which is why green stones exist on every continent.

How do I care for green marble and serpentinite?

Care depends on the specific stone type. Green calcite marble needs the same care as white marble: impregnating sealer every 12–18 months, pH-neutral cleaners, prompt wipe-up of acidic spills. Green serpentinite has different needs — it does not react to acids, but it is sensitive to moisture and temperature extremes. Seal serpentinite with a breathable impregnator, avoid prolonged water exposure (wipe wet surfaces dry), and never place very hot objects directly on the surface. Green quartzite is the lowest-maintenance option: seal annually, and it resists acids, scratching, and staining with minimal effort. Green onyx should be treated as a delicate decorative material — seal frequently, avoid all chemical contact, and use only for low-traffic decorative applications.
