Precious Opals (vs. ordinary gemstones)Most gemstones are graded with a gem microscope and other instruments that examine the tiniest details inside the gemstone or diamond and the angles of each facet on the outside surface of the gem.
You can't see this with the unaided eye. In fact, to your eyes, these common Diamonds and Colored Gemstones pretty much all look alike unless they are Very Bad!
So, you have to depend upon an Appraisal Certificate from a gemological testing company or a Certified Gemologist to tell you which one is better, where and why.
Natural Precious Opals require specialized training and education. Opals have special descriptive Terms and Grading that are exclusive to Opals! A jewelry retailer or internet seller may have decades of experience in the diamond or colored gemstone jewelry business. They may even be GIA Certified - & not know Precious Opals, how to grade Opals, how to appraise Opals or what makes a particular Opal valuable!
To appraise the value of a Precious Opal, the person doing the appraisal must be viewing at least dozens of Precious Opals every week. If you want to learn to appraise a Precious Opal, we believe that the best source of information is the book by the world famous Opal Expert, Dr. Paul Downing - 'Opal Identification & Value', about $50.
Every natural Precious Opal is Unique. No Two Precious Opals are Identical! And You can learn to see what makes one Precious Opal more Valuable than another!
Most of the Valuing of Precious Opals can be done without Equipment:

How to View Your New Opal
The Charm and The Magic
Your Precious Opal will look different in daylight, cloudy days, noonday open shade, tungsten lighting, halogen lighting, candle light, etc.This is part of the Charm & Magic of these Most Beautiful & Unique of God's Natural GemStones.
Your Precious Opal will Look Different & display Different Colors in different kinds of lighting. What Colors are seen, in what Shape or Pattern and from which viewing angles depends, in part, upon the viewing light used.
Sunlight & Tungsten Bulb Lighting will tend to bring out more Warm Tone Colors - Reds, Oranges, Pinks, Yellows, Magentas & Purples. ' Cooler Light' like viewing your Precious Opal in the shade, will tend to bring our the cooler Greens, Teals, Aquamarines & Blues with fewer reds and warm tone colors being seen.
As the Light Source, the Viewing Position between Your Eyes and the Opal and the Changing Angle at which you hold Your Opal are altered , Your Precious Opal can display Different Aspects of Her Unique Color & Pattern Personality.
The Best Light Source for viewing a Precious Opal GemStone is one that contains all colors of the visible light spectrum, like Direct Sunlight. We recommend Direct Sunlight or 12' from a bright Tungsten Lightbulb.
NO - fluorecent lights, LED flashlights or any light filtered through a lampshade or diffuser. These are not satisfactory light sources for viewing your Precious Opal and trying to evaluate the quality, B brilliance, N density or S color saturation.
ROCK, PIVOT, ROTATE & REPEAT
With the Precious Opal in your hands, Viewing it in Direct Sunlight or 12 inches from a bright Tungsten or Halogen Light:
Rock the Opal side-to-side and top-to-bottom
Pivot the Opal Gemstone
Rotate the Opal 90 degrees and Repeat
And Repeat until you have Rotated it 360 degrees
Change the Angle between the Opal, the Light Source and Your Eyes and Repeat. Rock the Opal side-to-side, top-to-bottom and pivot it to change the viewing angle.In a minute or so, you can see more about the personality of this Precious Opal than still photos or even a video can fully reveal.
Opal Play-Of-Color Flashes, Shapes & Patterns
Entire Books have been Written about the 'pinfire', 'rolling flash fire', 'picture', 'rainbow', 'palette', 'ribbon', 'cathedral window', 'asteria', 'chinese writing', 'flagstone', 'floral', 'cloverleaf', 'fish scale', 'harlequin', 'square' and other patterns of Precious Opals. Some Opal Vendors with good imaginations are inspired to give each of their valuable Opals a fanciful name for the image or inspiration they feel when they look at it.
Harlequin is a name originally reserved for an Extremely Rare Pattern of Squares or Diamond Shaped Play-Of-Color that looks like a chess board.
'Harlequin' is now used by Opal Vendors worldwide to encompass and identify many of the rare and unusual Natural Precious Opal Play-Of-Color patterns listed above. Pinfire, Flash, Picture, Flashfire, Rolling Flashfire or Broad Flashfire Play-Of-Color are not identified as Harlequin patterns.
NOTE - We will make this a separate subject for an upcoming Opal Guide with plenty of photos. Each Precious Opal we sell is classified and special Play-Of-Color Patterns are identified for that particular Opal. You can scroll through the loose opals and opal jewelry in our eBay store to view many of these Rare and Unusual Precious Opal Patterns and Colors.
Opal Brilliance - the 'B' #
The Play-Of-Color Brilliance of a Precious Opal is rated on a scale of B1 to B5. Dr. Paul Downing, the world famous Opal Expert, created this scale to grade the Brilliance of the Play-Of-Color or Precious Opals. This scale has been generally adopted worldwide. You will see many internet and eBay sellers who are generally following Dr. Downing's guidelines.
WHAT is a B4.7?NOTE - there are No internationally recognized grading numbers between, for example, a B4.5 and a B5 grade that clearly describe what would be the difference between a B4.7 and a B4.8 grades.
We use a PLUS - '+' to indicate an Opal is better/higher than a Standard Opal Brilliance Grading Number like a 'B4.5' and list it as a 'B4.5+'.
We use 2 PLUSES - '++' to indicate an Opal is almost but not quite the quality of the next higher grade - like a 'B4.5++' being almost a B5 grade.
B5 is BEST
The Best Possible Precious Opal Brilliance, 'B5', is extremely rare among all opals offered on world markets with Precious Opal Play-Of-Color visible in low light levels - sometimes called a 'Night Opal' or 'Night Stone'.
WE RECOMMEND - You look for Precious Opals rated B4, B4.5 or even B5 if you can afford the extra investment. MyLegacy-Treasures does not sell Precious Opals with a Play-Of-Color Brilliance below B3.
