Opals

You shine in the sun, and dim at night,
You make me special, and make me bright.
There is only one spot where you can be found,
That is buried deep far under ground.
There you are laying under the soil,
Waiting to be found through hard work and toil.
You can be valuable and worth a mint,
The lightning of your colour gives off a nice tint.
There you lay shining so beautiful and bright,
For when it is dark all you see is your light.
People come from around the lands,
To hold a piece of you in their hands.
You can be the most beautifulest jewel ever found,
When clean and polished you are smooth and round.
You bring joy to the young and to the old,
This is what I have been told.
Green, red, black and blue,
Everyone wants a piece of you.
A bracelet, necklace and ring you can be,
A precious treasure just for me.
