Valerio Belli (c. 1468–1546), also known as Valerio Vicentino, was a celebrated medallist, gem engraver, goldsmith, who with Giovanni Bernardi, who was twenty years younger, was the leading specialist in intaglios engraved in rock crystal, a difficult luxury form which Belli pioneered. These were highly sought after by wealthy Italian collectors. Though described as being "engraved", the intaglios are cut by drills, sometimes quite deeply, and developed their style from classical coins and engraved gems, to give "smoothly and eloquently orchestrated figural compositions". [1] Castings of many of the crystal carvings were taken in wax and them used to make metal plaquettes, which Belli also designed and made de novo. He was described as a goldsmith, though no surviving works are known, and had some role at the Papal mint, though no coins are clearly attributable to him. [2]
Born in Vicenza, he was also active in Rome, his most important period, and Venice before returning to his native city in later life. In metal he designed many portrait medals and plaquettes, including copies of his works in crystal. He was mentioned by the art historian Giorgio Vasari, and drawn by Parmigianino (now Museum Boijmans Van Beuningen). Another profile portrait bust in stone relief is in the Victoria and Albert Museum, [3] and there is a similar self-portrait medal. A small round portrait, dated 1517 and formerly owned by Kenneth Clark (now in the Juan Abelló collection, Spain), may be by Raphael. [4]
His most famous work is a casket, now in the Pitti Palace in Florence, commissioned by Pope Clement VII as a wedding present to the future King Henry II of France and Catherine de' Medici. This has 24 scenes from the Passion of Jesus in crystal. [5]
Engraving is the practice of incising a design on a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engravings, a form of relief printing and stone engravings, such as petroglyphs, are not covered in this article.

Jacopo Caraglio, Giovanni Jacopo Caraglio or Gian Giacomo Caraglio known also as Jacobus Parmensis and Jacobus Veronensis was an Italian engraver, goldsmith and medallist, born at Verona or Parma. His career falls easily into two rather different halves: he worked in Rome from 1526 or earlier as an engraver in collaboration with leading artists, and then in Venice, before moving to spend the rest of his life as a court goldsmith in Poland, where he died.
A plaquette is a small low relief sculpture in bronze or other materials. These were popular in the Italian Renaissance and later. They may be commemorative, but especially in the Renaissance and Mannerist periods were often made for purely decorative purposes, with often crowded scenes from religious, historical or mythological sources. Only one side is decorated, giving the main point of distinction with the artistic medal, where both sides are normally decorated. They can usually be held within a hand. At the smaller end they overlap with medals, and at the larger they begin to be called plaques. They have always been closely related to the medal, and many awards today are in the form of plaquettes, but plaquettes were less restricted in their subject-matter than the medal, and allowed the artist more freedom.
Bonifacio Bembo, also called Bonfazio Bembo, or simply just Bembo, was a north Italian Renaissance artist born in Brescia in 1420. He was the son of Giovanni Bembo, an active painter during his time. As a painter, Bonifacio mainly worked in Cremona. He was patronized by the Sforza family and was commissioned to paint portraits of Francesco Sforza and his wife Bianca Maria Visconti. Scholars have credited him as the artist who produced a tarot card deck for the Visconti-Sforza families, now held in the Cary Collection of Playing Cards at Yale University. In the past century, art historians have begun to question the authenticity of his works, believing his only two secure works to be the portraits of Francesco and Bianca Maria Sforza. He is believed to have died sometime before 1482.

An engraved gem, frequently referred to as an intaglio, is a small and usually semi-precious gemstone that has been carved, in the Western tradition normally with images or inscriptions only on one face. The engraving of gemstones was a major luxury art form in the ancient world, and an important one in some later periods.
Hardstone carving, in art history and archaeology, is the artistic carving of semi-precious stones, such as jade, rock crystal, agate, onyx, jasper, serpentinite, or carnelian, and for objects made in this way. Normally the objects are small, and the category overlaps with both jewellery and sculpture. Hardstone carving is sometimes referred to by the Italian term pietre dure; however, pietra dura is the common term used for stone inlay work, which causes some confusion.
