I have been reading that titanium crystals have greater light
dispersion than diamond. Are they used in ring stones?
peter, the crystal is “strontium titanite” not titanium; it is used
as a diamond simulant, and does have a higher birefringence than
diamond.

John, Didn’t you mean strontium titanite has a higher “refractive
index” than diamond rather than “birefringence”?. Diamond, being
cubic, therefore singly refractive, of course has no birefringence.
Jerry in Kodiak
it has both, the RI is greater and being doubly refractive if has
birefringence also.
