Where is Giallo Siena marble quarried?
Sovicille, in the province of Siena, Tuscany, Italy.
Answer
Is Giallo Siena marble the same as Broccatello di Siena?
The stone itself
They are catalogued separately. Several supplier listings carry Broccatello di Siena as an alias of Giallo Siena, and this site records the name but does not use it as an interchangeable label, because Broccatello is a breccia and the two are catalogued as different variants.
The figures
| Name | Status on this site | Source |
|---|---|---|
| Giallo Siena / Giallo di Siena / Giallo Siena Unito | The stone this site is about | Published stone sheet |
| Siena Brocatello / Broccatello di Siena | Catalogued as a separate variant | Published stone sheet |
| Why it matters | Two names on two documents may not be one block | Our own catalogue |
Why this stone behaves this way
The trade uses names loosely, and the same name can travel between two different blocks. The way to tell them apart is the batch and the certificate, not the word on the order.
What these figures are, and what they are not This page states how this site catalogues the names. It does not say that a supplier listing is wrong, and it does not describe the Broccatello variant.
