The 'shine' phenomenon that you describe is due to diamond's high (2.4) refractive index.
You can look at the link below, to learn more about where diamond's refractive index fits on the list.
In direct answer to your question, these materials have a higher refractive index:
- Moissanite, 2.65 - 2.69
- Cinnabar (Mercury sulfide), 3.02
- Gallium(III) phosphide, 3.5
- Gallium(III) arsenide, 3.927
- Silicon, 4.01
Only moissanite in this list is suitable competition to diamond in the gemstone arena.
