GSI Card

We encourage our clients to view and utilize the attached GSI specification chart on color range and quality levels of travertine.

This universal method of educating and creating transparency for assessing travertine quality levels will ultimately create clarity and clear expectations in a universal language around the world for our clients to follow when identifying quality levels and price points.

Think of the attached chart as you would when purchasing a diamond ring and I think you will easily understand the importance.
