White/Grey travertine

Because of travertine’s antique color and effect, in the recent 10 years, it is so widely attracted by a lot of designers, contractors and owners. 
They are used for interior or exterior walls, paving, steps, swimming pool tiles etc.
Most of the travertine are from Turkey or Iran, and also we have our own Chinese travertine in the market. 
Any request for travertine, pls kindly contact me then.
