The Seerstone that the Prophet Joseph Smith used was, according to the Millennial Star, vol. 24, p. 86, a chocolate-colored stone about the size of an egg that was oval in shape. It was found by Joseph in a well when working for Clark Chase in the year 1826.” (Reminiscences of the Prophet Joseph, by Edward Stevenson, p. 30)

Henry Harris recalled: 

After he [Smith] pretended to have found the gold plates, I had a conversation with him, and asked him where he found them and how he come to know where they were. He said he had a revelation from God that told him they were hid in a certain hill and he looked in his stone and saw them in the place of deposit…

Martin Harris confirmed that Smith used the Chase seer stone to find the gold plates: 

“…Joseph had a stone which was dug from the well of Mason Chase…In this stone he could see many things to my certain knowledge. It was by means of this stone he first discovered these plates.”

Comprehensive History of the Church Vol. 6, p. 230: 

Dedication of the Manti Temple with the Seer Stone on the Altar.  One item mentioned by President Woodruff about the private dedicatory services at Manti is of more than passing interest. “Before leaving,” he writes, “I consecrate upon the altar the Seer Stone that Joseph Smith found by revelation some thirty feet under the earth (ground), and carried by him through life.” This is the very Seer Stone that the Prophet Joseph Smith used part of the time when translating the Book of Mormon; the one he took from the well he was digging with his brother Hyrum, near Palmyra, for Mr. Clark Chase,…”

Richard S. Van Wagoner, Sidney Rigdon:

A Portrait of Religious Excess, Signature Books, SLC, 1994, p. 57:  “This stone, still retained by the First Presidency of the LDS Church, was the vehicle through which the golden plates were discovered and the medium through which their interpretation came.”

Early Mormonism and the Magic World View, by D. Michael Quinn, Signature Books, Revised ed. 1998, pp.242-243: 

“About 1982 one of Brigham Young’s descendants was allowed to see this seer stone in the First Presidency’s office. Mary Brown Firmage Woodward afterwards stated:  “The stone was not chocolate brown but rather the color of brown sugar. It was 3-4 inches long, 2 inches wide, and had a hump in the middle which made it perhaps 2 inches thick at the thickest point. It was flat on the bottom and had three black, concentric circles on the top 1/2 inch. Below the circles were many small black circles. The stone was not transparent.” The First Presidency’s secretary told her that the presidency’s vault contained two additional seer stones.”

David Whitmer, one of the three witnesses and a scribe for Smith, stated in his testimony to J. L. Traughber (Saints’ Herald 26 (November 15, 1879): 341):

With the sanction of David Whitmer, and by his authority, I now state that he does not say that Joseph Smith ever translated in his presence by aid of Urim and Thummim; but by means of one dark colored, opaque stone, called a “Seer Stone,” which was placed in the crown of a hat, into which Joseph put his face so as to exclude the external light. Then, a spiritual light would shine forth, and parchment would appear before Joseph, upon which was a line of characters from the plates, and, under it, the translation in English; at least, so Joseph said. [16]

In 1881 David Whitmer made a statement to the Kansas City Journal:

“on June 5, I, as well as all of my father’s family, Smith’s wife, Oliver Cowdery, and Martin Harris were present during the translation. The translation was by Smith, and the manner as follows: He had two small stones of a chocolate color, nearly egg shaped and perfectly smooth, but not transparent, called interpreters, which were given him with the plates. He did not use the plates in the translation, but would hold the interpreters to his eyes and cover his face with a hat, excluding all light.”

From Mormonism Unvailed (1834), p. 241-248: 

TESTIMONY OF WILLARD CHASE  Manchester, Ontario Co. N. Y. 1833. I became acquainted with the Smith family, known as the authors of the Mormon Bible, in the year 1820. At that time, they were engaged in the money digging business, which they followed until the latter part of the season of 1827. In the year 1822, I was engaged in digging a well. I employed Alvin and Joseph Smith to assist me; the latter of whom is now known as the Mormon prophet. After digging about twenty feet below the surface of the earth, we discovered a singularly appearing stone, which excited my curiosity. I brought it to the top of the well, and as we were examining it, Joseph put it into his hat, and then his face into the top of his hat. It has been said by Smith, that he brought the stone from the well; but this is false. There was no one in the well but myself. The next morning he came to me, and wished to obtain the stone, alledging that he could see in it; but I told him I did not wish to part with it on account of its being a curiosity, but would lend it. After obtaining the stone, he began to publish abroad what wonders he could discover by looking in it, and made so much disturbance among the credulous part of community, that I ordered the stone to be returned to me again.  He had it in his possession about two years. –I believe, some time in 1825, Hiram Smith (brother of Joseph Smith) came to me, and wished to borrow the same stone, alledging that they wanted to accomplish some business of importance, which could not very well be done without the aid of the stone. I told him it was of no particular worth to me, but merely wished to keep it as a curiosity, and if he would pledge me his word and honor, that I should have it when called for, he might take it; which he did and took the stone. I thought I could rely on his word at this time, as he had made a profession of religion. But in this I was disappointed, for he disregarded both his word and honor. In the fall of 1826, a friend called upon me and wished to see that stone, about which so much had been said; and I told him if he would go with me to Smith’s, (a distance of about half a mile) he might see it. But to my surprize, on going to Smith’s, and asking him for the stone, he said, “you cannot have it;” I told him it belonged to me, repeated to him the promise he made me, at the time of obtaining the stone: upon which he faced me with a malignant look and said, “I don’t care who in the Devil it belongs to, you shall not have it.”
