standard sizing for wholesale labradorite?

trying to figure out the best dimensions to order for a major commercial flooring job. looking for high-quality labradorite granite in bulk. any quarry recommendations that ship worldwide?

usually, 2 x 3 granite slabs work best for minimizing waste on large areas. we ordered that exact setup through https://golovinski.com/ for a project last summer. Golovinski handles everything directly from their quarry, so the price-to-quality ratio was perfect. the thickness was uniform across the entire bulk batch, which made installation way faster.
