How to move object to the right?

Hi!
I’m looking for some small solution for move object to the right when OnTriggerEnter.
Now I have that:

Vector3 position = new Vector3(Random.Range(0,60.0F), 1, Random.Range(0,60.0F));
	Instantiate (Diamond, position, Quaternion.identity);

But that gives me position starts from the left when I want locate my object 10f further to the right from current location for example.

Vector3 offset = new Vector3(10f, 0, 0);
Vector3 position = new Vector3(Random.Range(0,60.0F), 1, Random.Range(0,60.0F));
Instantiate (Diamond, offset + position, Quaternion.identity);
