ODE to Gemology
By a GIA On-Campus Student
Dispersion, fire, aventurescence,
Orient, sheen, or iridescence—
Refractive index—high or low—
The luster should indicate that, you know.
Polarization—double or single—
What to do now! They intermingle!
Pleochroic colors you really should see;
Was that only two, or actually three?
Birefringence should help you a lot—
Use your polarizer, and watch the spot.
Now did it jump most, on low or on high?
Sure you can get it; if you really try.
Your liquids should be an aid, I think.
Does it float, suspend, or slowly sink?
Just use your imagination now—
(He doesn’t see me wiping my brow!)
Solid inclusions, or only bubbles?
Huh! They brush right off! I still got troubles—
Look for crystals and fingerprints—
Are the striae straight or are they bent?
You finally make your indentifications—
“You only missed one! Congratulations!
You’re doing fine! It’s just speed you lack!”
(I feel like using a well-placed tack.)
This scientific approach is tough
And you feel like shouting, “I’ve had enough!”
But, sooner or later, you see the light
And you know that this approach is right.
So to all who have helped us may we humbly say,
“Thank God, we had you to show us the way
To a life that is full of the things that are real—
And the appreciation you’ve taught us to feel
For the things which Nature so graciously gives—
You’ve given us something by which to live.”
“Anomalous”
