Onyx gets its name from the Ancient Greek word for nail. It is said that the goddess Aphrodite was resting on the bank of the River Indus when Eros fired an enchanted arrow at her. The tip of the arrow sheared off her nails and they fell into the water coming to rest on the riverbed where they turned into onyx.

How does Onyx form in nature?

The geological truth behind onyx’s true formation is no less amazing than this ancient myth. Just as stalactites and stalagmites are formed by the precipitation of minerals from water trickling slowly through caverns and caves, so too does onyx come into being.

A sedimentary rock with a cryptocrystalline construction, onyx acquires its translucence as a result of the size and uniformity of its crystals. It’s one type of the silicate mineral chalcedony, which in itself is a form of microcrystalline quartz.

Agate is also a type of layered chalcedony, but whereas the bands of silicate mineral that make up this gemstone are curved, those that make up onyx run parallel.

Onyx comes in many forms

In times gone by, all chalcedony was referred to as onyx whatever its colour or banding. Often still considered to be a black stone, onyx comes in every hue. If layered, the different shades that make up its bands are reminiscent of the veining in marble and as such, they lend it a similarly timeless appeal. A light rock, whatever its colour, onyx is soft and fragile and while not as robust as marble, it certainly has a similar translucence and uniqueness.

Onyx & Interiors

Onyx is a stone that, again, just like marble, sits beautifully in any interior, be that contemporary or traditional. This is partly down to its versatility; whether it embodies discreet neutrality or is a more dynamic, dramatic piece, onyx has the ability to pair sensitively with other materials, both organic and manufactured.

Ancient Superstitions - The History of Onyx

The superstitious beliefs of many different peoples have centred upon onyx. In Persia it was thought that the semi-precious stone could relieve epilepsy whereas in Renaissance Europe, a person who held it would become more articulate. The Ancient Romans, believing it would lend them courage in battle, carried onyx amulets engraved with Mars, the god of war. English midwives meanwhile thought it could ease childbirth and in periods of mourning during Victorian times, the stone was used to convey grief and sadness.

For thousands of years therefore, onyx has been used for a multitude of purposes. As a precious gemstone in jewellery or for ornamental carvings, it was highly prized by both the Romans and the Ancient Greeks. Relatively soft and therefore comparatively easy to carve, it was used to make figurines of the gods for burials and ceremonies, and also, for other more utilitarian purposes like bowls and cups.

Nowadays, as a gemstone, onyx is thought to bring strength and stamina, enhancing both durability and self-control. Said to deflect negativity whether the source is internal or external, it protects against bad luck arising from jealousy. Whether or not this is true, what can certainly be said is that an object hand carved from onyx - with its smooth patina and diaphanous quality - is an asset to any space.

A stone unique and versatile that has been recognised as such by civilisations for thousands of years, marble is adored for its aesthetic qualities as well as its durability and long lasting nature. A metamorphic rock, marble is created deep in the earth’s crust where limestone sediments have crystallised from being under considerable pressure and intense heat.

Carving Marble - Vision & Forethought

Throughout history and until relatively recently, all marble was carved by hand. In many places, it continues to be sculpted using time honoured and traditional techniques.

Though slow and painstaking work, requiring not only large amounts of skill and expertise but invariably also forethought and vision, marble is an ideal material for stone cutters because it is ‘soft’ when first quarried. It is this softness, combined with its chalky white surface, which allows many diverse and contrasting textures to be achieved.

Even better, marble hardens over time; whatever is hewn out of this incredible rock lasts therefore into perpetuity. Marble’s metamorphism continues therefore above ground, even after it has been quarried and not just as a result of the whims of sculptors and stonemasons.

Working with Marble, Time honoured & traditional techniques

Computerised carving machines now exist, but many sculptors and carvers today still use the very same tools employed by their forbearers in ancient times. First, the marble is split using a pitching tool, which is essential a hefty chisel with a broad, blunt edge.

The object to be carved – whether a sculpture or a piece of furniture - is roughed out and then a point chisel struck by a mallet is used to concentrate a blow of force on one particular point, bursting stone away. The point chisel is one of many similar tools. Stonecutters and sculptors will also use round chisels, toothed chisels, claw chisels and flat chisels, as well as angle grinders and hand drills to form and shape their work.

A marble sculptor will also need a selection of hammers, both for hitting the chisels and striking the marble directly. Towards the end of the sculpting process, rasps with fine teeth and rifflers, as well as files and abrasive rubbing stones or sand paper are used to smooth rough edges and refine planes and contours.

Natural Marble - Always Unique & Exceptional

When considering all the changes that marble goes through - whether it is changing itself or change wrought upon it by humans - it is still perhaps at the hands of the sculptors and stone masons that the rock reaches its zenith.

Even before sculpted, no two pieces of marble are identical because of the different levels of mineral deposits that determine the veining.

Much like the fingerprints on the hands of the sculptors who carve the marble, no two pieces can ever be the same.

But it is not just this uniqueness that makes marble so praiseworthy. No other stone has the quality of lending itself so well to being carved and sculpted, whilst at the same time reflecting a deeply human quality; that of the appearance of skin. Marble’s mineral make up and fine grain lend it translucence as light enters the stone. Not only is it able to be polished highly, but also - in certain light – it glows.

Consequently, its surface is not hard and flat but possesses a depth pleasing to the eye. This translucence is known as subsurface scattering and also happens when light touches human skin. This is why, of course, we marvel at the skill of the sculptors who have created the great statues of history and the oftentimes-uncanny lifelike appearance of the statues themselves.

Purity & Clarity of Marble

Just as gemstones and crystals are said to promote healing and restore energy, marble itself is believed to provide both self-control and clarity. Additionally, marble is said to bring about stability, not just, of course, in its physical form as a building material, but also as a conduit to a calm and soothed emotional psyche. Used by the Romans and up until the Italian renaissance as a symbol of purity and immortality and now today, by renowned sculptors and craftspeople the world over, there is only one thing about marble that refuses to change over the centuries; its enduring ability to enrich our lives, whichever form it takes on.

Desirable Sustainability

Each one of the marble objects in AU’s collection has been hand carved by Italy’s stonemasons and all have been previously owned. But these vintage pieces are just as beautiful and striking – in both colour and design - as the day they were first hand chiselled from marble blocks; indeed, the fact that they have been loved by others previously makes them perhaps even more desirable. Aspiring, wherever possible, to recycle and reuse need not ever mean compromising on quality or level of artisanship. Though some of the objects may show slight signs of having been both pre-owned and pre-loved, it is these marks that make their sustainable credentials – in our eyes – even more desirable.
