old rose gold jewelry versus new
by: Anonymous

There is a lot of jewellery today called 9ct gold filled, which is exactly what it is not. I have noticed that a lot of this jewellery has a rosy hue and is described as 9ct rose gold filled. Is the genuinely old 9ct rose rolled gold items worth more than the 9ct rose gold filled jewellery items of today.

ROLLED GOLD
by: Anonymous

The layer of gold on these items is so very very thin as to be next to worthless. If they are not marked 1/20 etc then you would be looking at a few microns only

rolled gold
by: steve

The initials H G & S stand for a company called Henry Griffiths and sons, a jewellers and silversmiths who I think were based in Birmingham.

Rolled gold was made by literally rolling a sheet of gold onto a base metal and fusing the two together, so in other words, the item is not solid gold.

In the old days they used to sandwich mercury between the gold and the base metal and then heat it up, vapourising the mercury and fusing the two metals together, but many goldsmiths died from mercury vapour poisoning!

The difference between this and gold plating, apart from the manufacturing techniques, was that apparently if it were possible to remove the base metal from a rolled gold article, the gold would be sufficiently thick to stand up on its own, whereas of course the gold plated thickness is microscopic and so it couldn't.

The term rolled gold is still in use today in the UK as a legal description, though of course it wouldn't be able to be hallmarked.

Rolled Gold & Gold-Filled Jewelry. What's the difference?
by: Anonymous

Hi Bernie thanks for writing in.

Great question, first of all, if an item is marked with the term "ROLLED GOLD" it's just an older vintage jewelry hallmark which means: GOLD-FILLED. So let's talk a bit about GOLD-FILLED.

It's a confusing term to begin with because the name GOLD-FILLED implies that the article is filled with gold. Not true, in fact the very opposite is true....

First a tube of gold is formed in this case, 9Ct gold tube and then the hollow tube is FILLED with jewelers core metal.

So, if you have 22ct GOLD FILLED or ROLLED GOLD it means the outer gold shell (just the shell) is 22ct gold. The THICKNESS of the TUBE of GOLD determines how long the piece will wear.

Not all Gold Filled items are marked so transparently, ie. ROLLED GOLD or 1/10 RGP or 1/20 12 KG.F,

For example, in the 19th century American many pocket watch case companies had their own way of describing the thickness of the outer layers - it might say on the case, "Guaranteed 10 years" or "Guaranteed 20 years" etc. the years relative to the thickness of the gold layer.


By the way, some beautiful pieces of premier jewelry and antique jewelry are made of GOLD-FILLED metal.
