Fire and bolt gem help

Does anyone have a guide of a glyph that would drop better gems for my arcane build? The ones I have currently are the ones I've gotten from an older YouTube video and they seem very lack luster for damage at 99 arcane and a +6 weapon I'm not too familiar with bloodbornes weapons stuff I know they have different variants of the same weapons for more gem options but I'd like to have better options then a cursed gem that give +9 fire but drains my health
