Seforno: It was radiance, which has no color. It hints to the human soul, which is [initially] empty of all knowledge, and is prepared to receive it through investigation by choice.
Rashbam: Beneath the Feet of the G-d of Yisrael, they saw something that resembled the whiteness of a sapphire.
Moreh ha'Nevuchim (1:28): It was the understanding that, just like radiance has no color, Hashem first created a formless matter [and later formed the world from it].
Targum Yonason: It was a sapphire brick formed from a fetus that a young girl miscarried, and it fell into the mud that she was kneading. Hadar Zekenim - during the slavery, it was in front of Him. After the redemption, He placed it under His feet, and there was light and Simchah in front of Him. Then, when the Churban occurred, He threw it to the ground. 4
Rosh: It was a 'Sh'fir' (the sac in which a fetus grows). A woman miscarried it, due to the labor in Egypt, and when Hashem wanted to drown the Egyptians in the sea and the angel of Egypt complained, Gavriel brought it up to the Heaven to recall the labor of making bricks.
Sotah, 17a: It was a brick colored Techeiles (dark blue or turquoise) which resembles the Kisei ha'Kavod. 5
As the Pasuk says in Tehilim, 91:15 "I am with them in their troubles". Ramban: This is the same vision that Yechezkel had - See Yechezkel, 1:26.
Which Hashem now showed Yisrael to demonstrate that He was with them in their troubles.
Targum Yonasan: As the Pasuk states in Eichah, 2:1 "Hishlich mi'Shamayim Eretz Tiferes Yisrael ve'Lo Zachar Hadom Raglav".
Sotah (Ibid.): With reference to the Techeles of Tzitzis, the Gemara states that Techeiles resembles the sea, the sea resembles the sky and the sky, the Kisei ha'Kavod - as the Pasuk writes in Yechezkel, 1:26 "Like the appearance of a sapphire brick, in the form of a throne".
Why does the Torah add the word "ke'Ma'aseh Livnas ha'Sapir"?
Yerushalmi Sukah, 4:3: To treach us that the Egyptians did not only make them manufacture bricks, but they made them do all sorts of labor connected with bricks.
Oznayim la'Torah: It was to demonstrate to Yisrael that the harsh slavery had achieved its effect, inasmuch as their souls had now become pure like a sapphire and brought them close to the Shechinah - that they had attained the level of angels to announce "Na'aseh Venishma" - like angels.

Rashi: There were light and joy in front of Hashem from when Yisrael were redeemed. 1
Seforno: Refer to 25:10:5:4. Just like the Nefesh of the Galgal is devoid of any physicality, so the human soul is totally non-physical.
Why did Hashem show Yisrael the sapphire brick only now and not at the Yam-Suf?
Oznayim la'Torah: Because when Yisrael - exclusively - sang the Shirah at the Yam-Suf, they were celebrating their salvation that took place there (ince Hashem does not generally celebrate the downfall of Resha'im). 1 Consequently, he waited to celebrate the Ge'ulah from Egypt, as he had informed Par'oh he would. 2 until they arrived at Har Sinai. 3
As He explicitly told the angels, when they wanted to sing Shirah too.
Refer to 24:5:2.1:1**. See Oznayim la'Torah DH 've'Sachas Raglav'.
Following Hashem's instructions at the Burning Bush "Ta'avdun es Elokim al ha'Har ha'Zeh", of which showing Yisrael the sapphire brick was part.
QUESTIONS ON RASHI
Rashi writes that a sapphire brick was in front of Hashem at the time of the slavery, to recall Yisrael's affliction, and from when they were redeemed, "uch'Etzem ha'Shamayim la'Tohar." If so, why did they see the brick at the time of Matan Torah?
R. Chaim Paltiel: One side of the brick appeared like Livnas ha'Sapir, and the other side k'Etzem ha'Shamayim. At the time of the slavery, the former side faced Hashem's face, to recall their pain, and the latter side faced down. From when they were redeemed, it was reversed.
