1. A cover article comprising:
a glass sleeve structure having an internal cavity with an unpolished internal surface, a polished outer surface, and a non-circular cross section;
a first index-matching material disposed on at least a portion of the internal surface of the glass sleeve structure; and
a second glass structure comprising glass and disposed on at least a portion of the first-index matching material such that the first index-matching material is present between and in direct contact with the glass sleeve structure and the glass of the second glass structure,
wherein the glass sleeve structure has a first index of refraction, the second glass structure has a second index of refraction that is within ±25% of the first index of refraction, and the first index-matching material has a third index of refraction that is within ±10% of the first or the second index of refraction.
