i'm looking to get any information on materials with a 2.42 index of refraction
(like a diamond)i'll settle for a range between 2.3-2.5 as well
eden1891-ga,
There are numerous substances that meet your refraction criteria.
I've listed them below, as gleaned from several online lists:
http://www.ps.missouri.edu/rickspage/refract/refraction.html
Wulfenite 2.3
Chrome Yellow 2.31
Crocoite 2.31
Sphalerite 2.368
Chrome Green 2.4
Fabulite 2.409
Strontium Titanate 2.41
Diamond 2.417
Chrome Red 2.42
Anatase 2.49

Sphalerite 2.369

Arsenic trisulphide 2.4777
Barium fluoride 2.3816
Strontium titanate 2.4254
Zinc selenide 2.485
http://hypertextbook.com/physics/waves/refraction/
eglestonite 2.49
franklinite 2.36
perovskite 2.38
sphalerite 2.428
I checked a number of other lists as well, but the materials quickly
began repeating.
I trust this list fully meets your needs.
However, if you find you'd like any additional information, don't
hesitate to ask. Just post a Request for Clarification, and I'm at
your service.

Diamond has a remarkably high index, 2.42. Zinc Iron Sulphide
(Sphalerite) puts up good competition at 2.37. The common substitute
for diamond is Yittrium stablized Zirconia (YSZ), which has a cubic
crystal structure (Cubic Zirconia). CZ typically has an index around
2.17. Another high index material is Moissanite, a form of Silicon
Carbide with an index higher than diamond, around 2.67.
