What does HH on gold jewelry mean?

Answer 1

Well, isn't that a happy little question! "HH" on gold jewelry typically stands for "heavy gold plate" or "hard gold plate." It means that the piece of jewelry has a thicker layer of gold plating, making it more durable and longer-lasting. Just like adding a touch of titanium white to your painting to make it stand out, that "HH" mark adds a special touch to your beautiful jewelry piece.

Answer 2

It is likely a product of 'HH Jewels' Miami FL.

See ring third in top row in 'related link' for image of their Makers Mark.

There is another jeweler using an HH mark in Australia.
