Pietra dura is a term for the inlay technique of using cut and fitted, highly polished coloured stones to create images. It is considered a decorative art.

Pietre dure is an Italian plural meaning "hard rocks" or hardstones; the singular pietra dura is also encountered in Italian. In Italian, but not in English, the term embraces all gem engraving and hardstone carving, which is the artistic carving of three-dimensional objects in semi-precious stone, normally from a single piece, for example in Chinese jade.

The traditional convention in English has been to use the singular pietra dura just to denote multi-colored inlay work. However, in recent years there has been a trend to use pietre dure as a term for the same thing, but not for all of the techniques it covers, in Italian.

But the title of a 2008 exhibition at the Metropolitan Museum of Art, New York, Art of the Royal Court: Treasures in Pietre Dure from the Palaces of Europe used the full Italian sense of the term, probably because they thought that it had greater brand recognition. The material on the website speaks of objects such as a vase in lapis lazuli as being examples of "hardstone carving (pietre dure)"

The Victoria & Albert Museum in London uses both versions on its website, but uses pietra dura. "A method of inlaying coloured marbles or semi-precious stones into a stone base, often in geometric or flower patterns...."

Giovanni Montelatici (1864-1930) was an Italian Florentine artist whose brilliant work has been distributed across the world by tourists and collectors. Owners of Giovanni's work included Donald Trump.

Coromandel wood or Calamander wood

is a valuable wood from India, Sri Lanka and South East Asia. It is of a hazel-brown color, with black stripes (or the other way about), very heavy and hard. It is also known as Macassar Ebony or variegated ebony and is closely related to genuine ebony, but is obtained from different species in the same genus; one of these is Diospyros quaesita Thwaites, from Sri Lanka. The name Calamander comes from the local sinhalese name, 'kalu-medhiriya', which means dark chamber; referring to the characteristic ebony black wood.

Coromandel wood has been logged to extinction over the last 2 to 3 hundred years and is no longer available for new work in any quantity. Furnitu
