Peach black

== Description ==
A carbon black pigment obtained by charring the pits from peaches or cherries and later from nut shells such as walnut, almond, or coconut. The deep blue-black color was recommended for watercolor paints in the early 17th century. Vegetable blacks were rarely used in oil painting due to very slow drying times.

Pearl

== Description ==
A smooth, opaque, iridescent gem formed as a multilayered nacre deposit around foreign matter embedded in the shells of mollusks. Nacre is composed of aragonite crystals bound together with conchiolin. The nacre is built up in thin, concentric layers that grow at rates of less than a millimeter per year. Large, natural pearls a rarity with the largest known pearl weighing 93 grams. The shape of the pearl depends on the shape of the embedded inclusion so most natural pearls are not spherical. Salt-water pearls, also called Oriental pearls, are found in the Persian Gulf, Gulf on Mannar, Myanmar, Tahiti, Borneo, New Guinea, Venezuela, and Australia. Since 1920, pearls have been cultured commercially.

Pearl, cultured

== Description ==
A pearl produced by inserting a bead into a pearl oyster. As early as the 13th century, Chinese were inducing the growth of freshwater pearls. A viable commercial process for culturing pearls was patented in 1896 by Kokichi Mikimoto in Japan. The process involves placing a mother-of-pearl bead into the mantel of a live oyster. Over the period of a few years, the oyster covers the bead with several layers of nacre. This produces uniform, spherical pearls. The primary sources for cultured pearls are Japan and Australia with smaller producers found in China and Fiji. X-radiography is used to measure the thickness of the nacre layer and differentiate between natural and cultured pearls.
