Secondhand Ring Question: Hi, I have recently acquired a secondhand ring. I was told it was gold, set with an opal and white sapphires, and had originally been purchased in Malta.
Price: $9.49
The only mark I can make out is '750' stamped inside the band, and a single stamp, which I can't make out, further round the inside of the band.
Does it sound as if it is likely to be gold - and how can I tell if they clear stones are white sapphires - they are clear and bright and reflect the colours of the opal beautifully.
Hope you can advise.
Carolyn

Gold Hallmark on Chain Question: Hi, I have just been given a 24" gold chain that is only stamped 777.
I can't see any other marks on it.
What does this stamp or hallmark mean?
Answer: Hi - Ann here, and many thanks for your query - and your patience.
Your 24" (inches) chain (60 cms) should be stamped somewhere near the clasp. In this case you say you can see 777.
Gold is expressed in two ways - 14K for example - which means it has 14 parts of pure gold - the rest is a mix of silver and copper etc. As pure gold is 24 carat they also express it as a decimal value in parts per thousand.
In a normal case 14K would be shown as 585 because there are 585 parts out of 1000 being pure gold (as above).
18 carat gold is marked in decimal as 750 or .750 but as your chain is stamped 777 I would suggest it is slightly above that figure of 18ct quality.
Best check with an eyeglass around the clasp again in case you missed a stamp.
Hope you find this information useful.

Inside the band is stamped McCabe, a tiny kangaroo, 18, and then what looks like a xmas tree with no trunk.
Are you able to tell me what or who this refers to? See Australian Jewellery: 19th and Early 20th Century
My grandfather was at the WA goldfields in the late 1800's. I wonder if it comes from WA?
