Murano Glass Claim

This lunchtime, the Murano Glass woman has been pointing at three pieces of gold foil in a red photo frame. She claims that one is silver foil, one is 24 carat 'yellow' foil and another is 24 carat 'white' gold.

24-carat gold is 100% gold. Given that white gold is made by alloying principally with silver, how is it possible to produce '24-carat white' gold? Surely the only possible colour for 24-carat gold is yellow.

About 10 years ago I bought a Murano glass pendant with a piece of 24 carat yellow gold foil in it.

The gold weight would have probably been 0.00000000001 of a gram!

You are correct that you can't get 24ct white (or rose) gold.
