Why do you consider 2 inches, huge? No offense but, I think you are asking too much.
You must understand that this material can be quite expensive, especially when used a certain way. Swords decorated with conch/Mother of Pearl carvings are more expensive than otherwise. It also depends of the amount of work that went into it. I have seen artists make intricate decorations with it, and it is very time consuming and take much care and skill.
Also, if you are Hispanic/Mexican, you are probably a lot more partial to this as jewelry. 😅
