Verde Borgogna

Verde Borgogna is an Iranian prasinite (greenschist greenstone) with a dramatically dark green to black-green ground mass, shot through with burgundy-red mineral accents (hence the trade name 'Borgogna' = Burgundy), golden-yellow vein bands and creamy white calcite veins. Also traded internationally as Verde Borgogna Marble, Borgogna Green and Iranian Green; used for expressive wall cladding, bar counters, fireplace surrounds, decorative interior panels and prestige statement interior surfaces with a dramatic oriental character.

Verde Borgogna ist petrographisch ein Prasinit (metamorpher Grünschiefer-Greenstone aus dem iranischen Ophiolith-Gürtel, DNSA #6279), wird im Handel als 'green marble' vermarktet. Bei ROSSITTIS klassifizieren wir den Stein handelsüblich in der Marmor-Familie wegen Pflege- und Verarbeitungsähnlichkeit zu klassischen grünen Marmoren wie Verde Alpi.

About Verde Borgogna

Verde Borgogna lives on an unusually dramatic material effect with a dark green and burgundy-red composition. The ground tone is a deep dark green to black-green — typical of prasinites with their chlorite- and epidote-bearing mineral fabric — shot through with characteristic burgundy-red to copper-orange mineral accents and golden-yellow vein bands. These 'Burgundian' colour accents gave the stone its trade name: 'Verde Borgogna' means 'Burgundy Green' in Italian and describes the unusual colour combination precisely. Creamy white flowing calcite veins run across the slab pattern in striking curved lines — they are the result of later hydrothermal mineralisation that broke through the original prasinite fabric. On a polished surface the stone develops a warm, glowing, dramatic depth with the characteristic contrast between dark green, luminous burgundy red and creamy white — a unique statement material for architecture with an oriental, luxurious ambition.

Geologically, Verde Borgogna is an Iranian prasinite from the Iranian ophiolite belt — DNSA-confirmed under entry #6279 (VERDE BORGOGNA, prasinite, Iran). Prasinites are metamorphic greenschist rocks formed under low- to medium-grade metamorphism from basaltic volcanic rocks or ophiolites — the characteristic green colouring derives from chlorite, actinolite and epidote. The burgundy-red accents in Verde Borgogna derive from iron-oxide- and haematite-rich fracture zones that penetrated the prasinite fabric after the main metamorphism; the golden-yellow accents from limonite- and ferrous-oxide-bearing minerals. In international trade Verde Borgogna is sometimes marketed as 'green marble', but petrographically it is a prasinite (metamorphic greenstone), not a classic marble. At ROSSITTIS we classify Verde Borgogna, as is customary in the trade, within the marble family, because it is handled and marketed in the same way as Verde Alpi, Verde Ming and other green 'marble' trade stones. Within the wider Iranian prasinite range there are related stones such as Verde Galassia and Verde Tifone — all come from the Iranian ophiolite belt.

Technically, Verde Borgogna shows typical values for an Iranian prasinite. Bulk density is 2,675 kg/m³, compressive strength 117.5 MPa, flexural strength 14.0 MPa and water absorption 0.3 %. Mohs hardness is 5-6 (typical of prasinites — rocks richer in chlorite are softer than classic granite). Important: because of the calcite content in the white veins, Verde Borgogna is acid-sensitive — wine, lemon juice, vinegar or acidic bathroom cleaners can leave visible etch marks on the white calcite veins. On the green and burgundy mineral areas the stone is more robust. Verde Borgogna shares this acid sensitivity with other green marble trade stones such as Verde Alpi (Italian serpentinite marble) and Verde Ming.

At ROSSITTIS we carry Verde Borgogna as an unsized slab for wall cladding, fireplace surrounds, bar counters, prestige statement interior surfaces and bookmatch wall compositions, in tiles for wall applications, and for window sills and project-specific cutting. The typical application is the statement wall surface or bar counter with a dramatic dark green character and burgundy-red accents. The surface finishes currently held in stock are listed in the »Finishes« block further down. A flamed external application is possible, but because of the acid sensitivity and the soft carbonate veins, Verde Borgogna is intended primarily as an interior statement material.

Compared with classic Italian green marbles such as Verde Alpi (Aosta Valley, cooler green serpentinite marble) or Verde Ming (China, jade-like), Verde Borgogna brings the unmistakable burgundy-red mineral accents — a rare and highly distinctive composition. Compared with its sister material Golden Lightning (also an Iranian prasinite, but with golden-yellow lightning streaks on a green ground), Verde Borgogna is more dramatic and more intense in colour with the addition of the red accents. For architectural projects with an oriental, luxurious or dramatically warm character — hotel lobbies with a warm wow-effect atmosphere, bar counters in high-end restaurants, fireplace surrounds with statement ambition, prestige wall and façade surfaces with a dramatic material effect — Verde Borgogna is a very exclusive and expressive choice within the Iranian natural stone range.

Finishes

Verde Borgogna is available in a range of finishes. The finish affects appearance, feel and the care it needs.

Satiniert

Die Oberfläche wird gebürstet — weichere Minerale werden gezielt entfernt, es entsteht eine subtile Tiefe mit mattem Erscheinungsbild. Eine zurückhaltende Veredelung, die die schieferspezifische Schichtung in eleganter Mattigkeit zeigt. Pflegeleichter als die polierte Variante und alltagstauglich.

Care & fabrication

As an Iranian prasinite, Verde Borgogna is a decorative material with moderate robustness. Mohs hardness is 5-6, water absorption 0.3 %. One important qualification: because of the calcite content in the white veins, Verde Borgogna is acid-sensitive — wine, lemon juice, vinegar, cola or acidic bathroom cleaners can leave visible etch marks on the white calcite veins. On the green and burgundy mineral areas the stone is more robust.

For all applications, a silane- or polysiloxane-based sealer is mandatory. On polished interior surfaces we recommend refreshing the sealer every 2-3 years, and annually in heavily used areas. Sealing protects against deep penetration by acids, oil, grease and pigments — particularly important for the calcareous white veins.

Daily care is carried out with a pH-neutral natural stone cleaner and a soft cloth or microfibre mop. Clear warm water is usually sufficient. Consistently avoid acidic cleaners, vinegar-based cleaners, cement haze removers and strongly alkaline products — with Verde Borgogna this is particularly important because of the calcite content. The surface finishes currently held in stock are listed in the »Finishes« block further down.

Verde Borgogna is not recommended for kitchen worktops. The acid sensitivity of the calcite veins, the moderate hardness (Mohs hardness 5-6) and the heterogeneous material structure make the stone unsuitable for intensive cooking use. Wine, lemon or vinegar leave visible etch marks on the white veins. Possible for bar counters in prestige spaces with clear maintenance expectations and consistent sealing; unsuitable for everyday cooking. For carefree dark green kitchen worktops we recommend an acid-resistant green granite or quartzite.

For floors, Verde Borgogna can be used in moderately loaded interior areas (living rooms, prestige entrance areas), but because of the moderate hardness and acid sensitivity not in areas with heavy moisture exposure or high traffic.

For external applications, Verde Borgogna is intended primarily as an interior material. External applications are possible, but because of the acid sensitivity (acid rain) and the soft carbonate veins they are not recommended in northern, frost-prone climate zones. Possible in Mediterranean or warm climate zones with consistent sealing.

Frequently asked questions

What does 'Verde Borgogna' mean?

Verde Borgogna means literally 'Burgundy Green' in Italian and describes the material's unusual colour combination precisely — a dark green prasinite ground mass with characteristic burgundy-red mineral accents. In the trade the stone also runs under Verde Borgogna Marble, Borgogna Green and Iranian Green. The word 'Marble' in the trade name is commercially customary; geologically, however, Verde Borgogna is a prasinite (metamorphic greenstone), not a classic marble.

What is Verde Borgogna geologically?

Verde Borgogna is an Iranian prasinite from the Iranian ophiolite belt — DNSA-confirmed under entry #6279. Prasinites are metamorphic greenschist rocks derived from basaltic volcanic rocks or ophiolites, whose green colouring comes from chlorite, actinolite and epidote. The burgundy-red accents in Verde Borgogna derive from iron-oxide- and haematite-rich fracture zones that penetrated the prasinite fabric after the main metamorphism. At ROSSITTIS we classify the stone, as is customary in the trade, within the marble family, because of its similarity to Verde Alpi and other green 'marble' trade stones in maintenance and fabrication.

Is Verde Borgogna suitable for a kitchen worktop?

Not recommended. The acid sensitivity of the white calcite veins, the moderate hardness (Mohs hardness 5-6) and the heterogeneous material structure make the stone unsuitable for intensive cooking use. Wine, lemon or vinegar leave visible etch marks on the calcite veins. Possible for decorative bar counters in prestige spaces with clear maintenance expectations; unsuitable for everyday cooking. For carefree dark green kitchen worktops we recommend an acid-resistant green granite (for example Verde Maritaca, Imperial-Kerala Green) or quartzite (for example Verde Picasso).

Which finishes are available for Verde Borgogna?

The surface finishes currently held in stock are listed in the »Finishes« block on this page.

Where does Verde Borgogna come from?

Verde Borgogna comes from the Iranian ophiolite belt — DNSA-confirmed as an Iranian prasinite. Iran is one of the most important supplier countries for prasinite, onyx and marble. Related Iranian prasinites with a similar geological origin are Verde Galassia and Verde Tifone, as well as Golden Lightning from the same region. Internationally the stone also runs under Verde Borgogna Marble, Borgogna Green and Iranian Green.

How do I clean and care for Verde Borgogna?

Sealing is mandatory because of the calcite content in the white veins — refresh every 2-3 years on polished interior surfaces, annually in heavily used areas. Daily care with a pH-neutral natural stone cleaner and a microfibre cloth. Consistently avoid acidic cleaners, vinegar, citric acid and cement haze removers — the calcareous veins react to acids with etch marks. Dry cleaning with a soft microfibre cloth after damp wiping is advisable.

Verde Borgogna or Verde Alpi — which suits better?

Both are green metamorphic 'marble' trade stones with similar acid sensitivity and Mohs hardness, but with fundamentally different colouring and origin. Verde Alpi (Italian serpentinite marble from the Aosta Valley) shows a cooler dark green to black-green tone with white and black vein bands — classically elegant and Alpine. Verde Borgogna (Iranian prasinite) additionally brings characteristic burgundy-red mineral accents and golden-yellow vein bands — more dramatic and more intense in colour, with a warm oriental character. For classic Alpine green elegance, Verde Alpi; for a dramatic, warm green and burgundy material effect, Verde Borgogna.
