There may be no difference, depending on your source. The sword in the stone story is first found in the Story of Merlinattributed to Robert de Boron. Robert gives no name to the sword in the stone. He may have intended it to be identified with Arthur's sword Caliburn or Escalibor (named "Excalibur" by Sir Thomas Malory in his Le Morte d'Arthur) but does not explicitly say so.
The identification becomes explicit in an addition to the Story of Merlin which is today commonly known as the Vulgate Merlin which adds an account of the first five years of Arthur's reign, up to the entombment of Merlin and the birth of Lancelot. See http://www.archive.org/details/vulgateversionof02sommuoft , page 94, line 26 for the Old French version and see a Middle English translation at http://quod.lib.umich.edu/cgi/t/text/text-idx?c=cme;idno=Merlin;rgn=div1;view=text;cc=cme;node=Merlin%3A7 , page 118. Here Arthur fights with the sword Escalibor which is clearly identified with the sword Arthur had drawn from the stone.
There is also a late Welsh account based mostly on the Vulgate Merlin which identifies the sword in the stone with Arthur's sword, here called Kaledvwlch as is usual in Welsh texts. See http://www.maryjones.us/ctexts/kaledvwlch.html .
However there is an alternate version of Arthur's early years, today commonly known as the Post-Vulgate Merlin. In this version Arthur, with Merlin's aid, obtains his sword Escalibor from a hand and arm which rise from a lake. See http://books.Google.com/books?id=qjk27gRgV1IC&pg=PP7&dq=intitle:Merlin+inauthor:Paris&lr=&as_drrb_is=q&as_minm_is=0&as_miny_is=&as_maxm_is=0&as_maxy_is=&as_brr=0&cd=2#v=onepage&q=&f=false , beginning at page 196. An English translation of a Spanish adaptation of this work is found at http://members.terracom.net/~dorothea/baladro/index.html . Note that in this account the actual finding of the sword in the lake is omitted with other material that should appear between chapter 21 and chapter 22. But the story of the naming of the sword appears at the end of chapter 22.
No other early romance tells of the origin of the sword, save for a statement in Geoffrey of Monmouth's Historia Regum Britanniae that Arthur's sword Caliburn was forged in Avalon.
Sir Thomas Malory's Le Morte d'Arthur actually derives in its earliest sections from an account which mixes material from the Vulgate Merlin and the Post-Vulgate Merlin. Accordingly in Book I, chapter IX, Malory uses the Vulgate Merlin version in which Arthur's sword Excalibur is identified with the sword from the stone. But in Book I, chapter XXV, Arthur obtains the sword from the lake and in Book II, chapter III, this sword is said to be Excalibur. See http://www.sacred-texts.com/neu/mart/ .
The sword in the stone and Excalibur are 2 different things. Merlin put the sword in the stone in the stone( which by pulling it out made Arthur King Arthur), and Excalibur was the sword that came later after the sword in the stone broke. Excalibur came from the Lady in the Lake.
Caladfwlch, NOT Excalibur. The Sword in the Stone is the one that Merlin enchanted so that he could find the true King. Excalibur is from the Lady of the Lake.
The sword in the stone is called Excalibur. It is the legendary sword of King Arthur in Arthurian legend.
On the marble block, it was written: "Whosoever pulleth out this sword of this tone and anvil is rightwise King born of all England." **According to TH White's The Once and Future King, on page 200, the inscription is on the sword itself and not on the marble block or the anvil. The quote of the inscription is on page 201. There is nothing written on the stone or anvil. It's the sword, Excalibur, that's important. And for Arthur to draw.
There is some confusion about which sword was actually in the Stone. In some versions, Excalibur is the only sword in the story and the name Excalibur comes from the Welsh Caledfwlch. However, other stories have Arthur being given Excalibur by the Lady of the Lake some time after he began his reign (after he breaks the Sword in the Stone while fighting Lancelot).Arthur is a legend with many sources: Welsh, Irish, British and Norman.

The sword, as far as I know, had no name. Excalibur is a totally different sword. Arthur got Excalibur soon after breaking the sword in the stone in battle.

The magnificient Excalibur was cast into the stone by Merlin the wizard.
The sword in the stone was in a churchyard in London.
The sword in the stone is called Excalibur. It is the legendary sword of King Arthur in Arthurian legend.
Excalibur is a mythical sword, originally, pulled in a stone. The only true king was able to release it. It was the Arthur who took the sword out of stone and he was proclaimed the king.
No, but there is some confusion about which sword Excalibur actually was. In some versions of the legend, Excalibur was the sword that Arthur drew from the stone. In other versions of the same legend, Excalibur was the sword given to King Arthur by the Lady of the Lake.
In the history of king Arthur he finds a competition to pull a sword out of a stone. He pulled out the sword and he named it Excalibur.
He pulled the sword from the stone. this sword was not Excalibur.
Excalibur.
