Saraswati vs sri yantra

I’m on the verge of working with Saraswati. So I’ve been looking for a ring to keep her close. However, I’m having a hard time differentiating Sri Yantra and Saraswati. The interlocking triangles used are very similar. Are they considered the same thing? I found a ring with two interlocking triangles within a lotus flower which is generally the symbol for Saraswati.
