Diamonds

Diamonds:

There is nothing like a Diamond. It is the Hardest material (almost 140 times harder than its nearest gemstone) and is named after the Greek word ‘Adamas’ which means ‘Unconquerable’.

Unlike other gemstones, its primary perfection is based on LACK of colour. The pure colourless or White is the most Valuable, although many shades of Yellow are common.

Dating Jewellery and Gemstones:

I forgot to ask…around what time did they start marking gold w/K?

Or what time period did they just use hallmarks on the gold jewellery?

G’day Chandana and many thanks for your query

Colored Diamond Values

Colored Diamond Values Question:

Hello, last week I found a 1.34Ct rootbeer colored diamond, cubic in shape with slight valley like fissures.

Stone reflects metallic with rootbeer flashes.

Would a stone such as this have a higher value to a collector, or to have, “someone professional?” evaluate it?

It is really an attractive stone.

Thanks…

Answer:

G’day Alan and many thanks for your query

However I don’t know what you mean?

I am assuming you have been fossicking in the outback, and as you said “Found a 1.34Ct rootbeer coloured diamond”… Continue reading Colored Diamond Values

Identification of Cat’s Eye Gemstones Question:

Greetings from Australia.

I have inherited what I thought was cat eyes jewellery but I find they look nothing like the images on google.

My cats eyes are round, dime-size and have a eyeball look about them.

They have a dark green round centre, are surrounded by Creamy white and have a dab of rusty brown.

Thank you for your time.

Answer: G’day Joseph and many thanks for your query.

What you are describing to me is called Operculem Cat’s Eye, or sometimes called Chinese Cat’s Eye
