Which is the correct term: ratna traya or triratna

In Jain Dharma, both terms are used, but the more common and standard Jain term is Ratna-traya or Ratnatraya — meaning the Three Jewels:

1. Samyak Darshan
2. Samyak Jnan
3. Samyak Charitra

The term Triratna also means the same thing in general usage, but in Jain context Ratna-traya is usually preferred because it is the traditional Jain expression.

So, if you are asking for the most correct Jain term, use:

Ratna-traya (Ratnatraya)

If you want, I can also give the meaning of each of the three ratnas in simple Jain language.
