Same client as previous thread, except this opal is transparent (crystal) , but has a decent play of colour (multicolour)...13 x 11 x 3 mm oval cab, solid...hard time calling the base colour, almost a very light gray........

question is...what would you all suggest for pricing (ie. same as white opal, % above equivalent white opal) ? I'm going to call some of my contacts, but I thought someone out there might have some input.

ps. He was told it was a "jelly" opal, but from what I've read (Downing, etc.), if it has a play of colour, it is not a jelly opal, it's a crystal opal.

pps. Opals are such a pain in the :shock: ...IMHO, lol

I've seen "grey" opals sold as black opals (which, I suppose it's fair to call them).

Check this one out.

To answer where crystal fits, the cheapest is white, then matrix, crystal, semi and black at the top of the market. Some put these in a different order, but I am sticking with it for now. In pricing, you should also expect to evaluate the following;

Body tone – runs from 1 TO 9, and is generally graded as follows.
N1-N4 = black
N5-N6 = dark
N7-N9 = light

Transparency – from opaque to translucent, and is the primary indicator of crystal.

Colours – listing all the colours visible in opal, with the most evident first in the list and so on. Red, Orange, Yellow, Green, Blue are the most common, and in that order, making red the rarest, and most expensive. Other colours are found, such as purple, and can effect the price of the stone.

Brightness – runs in three grades from subdued, bright and brilliant, and has a significant effect on pricing.

Pattern – I won’t explain them all here, but in desirability order are;

Floral – most common, and a generic term
broad flash, rolling flash, Pin Fire – more expensive
Harlequin – rarest and most expensive, imagine checkerboard type effect, and extremely rare.

So all opal collectors drool over N1, translucent, bright red, brilliant harlequins!

Great information Martin. Do you happen to have some pictures for us that roughly illustrates this?

Hey Canadave,
Email a picture to info@codyopal.com
They are the leading opal specialists and dealers in Melbourne, if not Australia. They might be able to help. If they can't, I dont know who can.
Good luck
Meg
