‘She won’t be right’ mate! We do need an opal valuation system!

Posted in opal valuations, Opal, the gemstone on February 28, 2009 by opalmine

[“She’ll be right mate!” is a typical expression used by Australians to say, ‘near enough is good enough.’ Unfortunately this philosophy has become a part of our persona with resultant unfortunate business side effects. Just as well for us, we are starting to get a bit better organized in our way of doing things nowadays. Here is an example of that]

It must have been thirty five years ago when I first met Peter Evans. As I remember, he was sitting at an opal cutting machine somewhere in Sydney, attempting to extract the best polish for Queensland boulder opal, with its challenging matrix of ironstone. Never one to hold a secret for long, he revealed, ‘Just try using an old nylon carpet, charged with tin oxide.’ ‘That’ll bring the shine up on this stuff”

Peter has been at the forefront of the opal industry for a long time. A genial, helpful guy with a determined glint in his eye and a stack of advice, he has obviously thought long and hard about the opal stone. Set against the backdrop of how us ‘Auzzies’ do things in an ad hock sort of way, Peter is a far cry from the “She’ll be right” mentality. Always quizzing things. Always inventing. A self made man who is not afraid to put his ideas into action and challenge the status quo.

And challenge he has. Particularly when you think of tackling the problem of creating a grading system to simplify opal valuation. Such a system, if successful, would be a piece of equipment in demand by every jeweler in the world worth his metal [if you’ll excuse the pun]

The difficulty we have in arriving at a consistent opal valuation system is that opal is not like any other gem stone. Most gems have a certain consistency of color and clarity, making them not so difficult to categorize and value.

Opal however is the renegade of the gem world. Its colors and patterns challenge the imagination. You think its one color and it suddenly flashes a different color. You see a pattern on one end of the stone, and it swaps to another pattern on the other end as it is rocked to and fro. The varieties of opals are endless. It is one of the most interesting of all industries to be involved in. Once you are bitten by the opal the bug, the bite is deep and lasting.

This then is what Peter had to address. How do you get a dumb computer to analyze color, clarity, background, pattern, imperfections, and shapes? Most of us are still wondering how he did it, but he has indeed accomplished it, even though, already there have been a number of revisions of his original program.

What we already have though, is a consistent system taking into consideration the nomenclature established by the gem industry association in Australia. [see: http://www.opal.asn.au/nomenclature.htm Anyone in the world, with a computer can access what has been not so modesty but legitimately described as “The Smart Chart” Available online at www.opalmine.com Imagine, if everyone in the world starts using this system, there will be no more confusion as to whether an opal is real or not, or whether its value is right or not.

The Ordinary Bloke’s Guide to Opal Cutting and Polishing – Part 2

Info box: Well, really there is no such thing as an ‘ordinary’ person. we are all unique and we all have our skills that differ from someone else. However if you want to learn opal cutting and show off some of your work, or use it as money saving gifts… read on.

By Peter Brusaschi
So you are an ordinary “bloke” or “guy” or “gal” as the Americans would put it!! Maybe you’re not so ordinary. Maybe you know a lot more about the gem industry than I do. Maybe you are an expert opal cutter with years of experience. Whoever you are, it doesn’t really matter. If Len Cram reads this book, he’ll probably say to himself…”Brusaschi, ya don’t know what ya talking about!” That’s why I’m going to give it to the old expert himself to read before I publish a book. In the meantime it can stay on CD.
After cutting opals for about 30 years, one day an old bloke walked into the Opal Miner’s Hut and said: “How do you “dop” an opal?” After a lengthy description of the traditional heated sealing wax method, he said “That’s a bit of a long winded way of doing it!!” I swallowed my pride and listened to his simple suggestion. His idea revolutionized my thinking of this procedure and caused me to create new, easier, and inexpensive methods of cutting opals.
What is learned from an experience like that is that we don’t stop learning no matter how much you think we know about a subject. From my experience in life, the danger in being an “expert” is that we can become tunnel visioned in our approach to things. No matter how much experience one has had, there is always someone else who may disagree and have a better idea. If you have a better idea than I have expressed, please tell me. My ears are flapping!
Having said that, I believe what is needed to work the stone, and gain tremendous satisfaction out of producing a gem, is a little common sense and ability to work with your hands. Most of us started off without the valuable experience recorded in this book or CD, so if you read it carefully, in just a short time, you should accomplish what it took the author ten years and thousands of dollars worth of mistakes to find out.
I must also state that I have a few reasons for writing this book. First, it’s the only book I have ever written or am likely to write,. so it’s a good challenge. Secondly it will hopefully make more people aware of this magnificent stone, and get much pleasure out of either cutting it, dealing in it, or both. And thirdly it may encourage more people to buy it and help all the people including myself and the rest of the battling opal miners in Lightning Ridge and other fields to sell more opal.
I think that the more people know about opal, the more opal will be bought and sold. Then everyone will be making a better living. That is why the book or CD does not just tell you about opal itself, but later lets you know how other people feel about the stone and what you can do to turn it into a business.
You can only get a certain amount of help out of books. The rest is left up to practice. You have to experience the feeling of stones popping off dop sticks to learn how to avoid it. If you want to give yourself a kick start, why not join a lapidary club for a while. If you want to see if there is a club in your area, please check: http://www.lapidaryjournal.com/archive/clubs.cfm If you do this however, take this tip from a person who has had a lot to do with all sorts of gemstones apart from opal over the past thirty years. In my opinion it’s better to learn the art of cabochon cutting rather than facet cutting for the following reasons: [to be continued]
