Gems of inestimable value

Teachers do their best, they really do!  It’s also true sometimes that best shot is far off the mark.  Parents also are far from perfect.  So the whole business of education, from conception to grave, is not an industrial production line and indeed never should be.

Teaching occasionally allows you to see the real gems that have been produced.  You marvel at the beauty of the stone, the cut faces positioned to catch and reflect the light.  Each one gloriously unique.  Then despite efforts, or due to lack of attention there are the flawed stones.  They can have defects deep within, an odd crack destroys the pristine surface.  You sense all is not well in how they relate to others.  Even their ability to reflect virtues has been reduced.  Whoever cut these stones was not adept but careless.  Huge sections have been hacked out by random blows.  A part of you longs to see this gem unspoiled before the cuts of life have seared them.  But this is an idle wish and the focus must be on the task in hand.  Hidden away within this flawed stone there is strength, a tone of colour rarely seen.  Finding these “gems of inestimable value” in ourselves and others is all that matters.  Often, they are found in dark places and for good practical reasons. 

After all, diamonds are formed 2000 miles below the earth’s surface at that boundary between the core and the earth’s mantle.  Plumes of heat from this part, at 4000 degrees Celsius, rise upwards towards heating the stones above.  Certain types of rock (called kimberlites) are volatile when heated and explode violently spewing diamonds up towards the surface with their eruptions.

Finding gems in the darkness below the earth, where light cannot reach requires effort.  You need to identify among all the dead stone the priceless and in its natural state the uncut diamond does not hint at its glory within.  You need to become experienced at identifying the potential, its capacity.  This is the first task.  Note, how uncut natural diamonds look.  Disappointing, isn't it?



Then the gemstone must be taken to the light.  Only when exposed to the edification of learning, growing, discovering and being tested can it begin to shape itself.  The next stages are fourfold and it is good to understand them all.  Finding the gemstone is only the beginning of a delicate and precise art.



Planning

The size, clarity and crystal direction is examined when deciding where to mark the diamond.  Here, the eye has to see the end in the beginning.  Perhaps, there are three parts each of which will produce lovely gems.  Despite the loss in size, the expert can see the end result will be more perfect stones.  This part involves marking where the slices will be made.  Decisions are taken as to where you will cleave, at what angle and on what plane.  Without awareness it is possible to shatter the stone and end up with something worthless.  We need to plan


Cleaving or sawing

To cut the hardest stone you need to use diamonds.  Only they are hard and pure enough to make the cleave correctly.  With cleaving, the new pristine surfaces are revealed.  These surfaces have never been exposed to air or light and their purity is startling.  This is not a small challenge.  Every stone is unique, its planes at different angles with unexpected shades of colour millimetres beneath.  With good planning your cleave begins to release the beauty within.  But incredible force is necessary and pain is a necessary part of this process.  


Bruting

This is where the diamond is literally grated against another diamond to create a basic shape.  During bruting you try and not lose unnecessary stone but you have to prepare the stone so that facets can be created. This is also known as girdling or rounding. The girdle is the band which is formed around the thickest part of the stone.  The stone is rounded off by such close contact.  The process requires others we cannot do this alone.  It is in service to our community with others we find our basic shape. – Brutal shaping from others!


Polishing

Polishing is the final stage of the cutting process, giving the diamond its finished proportions.  Often 17 or 18 facets are made creating a single cut.  It is this final stage that will determine how much brilliance and fire a diamond can display. Minor inconsistencies in symmetry and proportions can make the difference between a luminous diamond and a dull, lifeless stone.  You must work on what you find within not some blueprint you might have in your head.  The stone must come alive to its potential and you must let go of your expectations.  Fundamentally, it is the gem’s ability to reflect the light at angles and colours of their own creation that you long for.  If a production like mentality is adopted you damage the priceless for the mundane. 



Letting go!

As an educator or as one who has been educated, or ideally both the final stage is letting go.  You must throw away these priceless gems.  No keeping them in crowns or cabinets to gloat over.  It is in scattering far and wide these glistening reflectors of light this world is made a brighter place.  You need to be detached because you have no ownership here.  The product is sometimes better and brighter than anything you have ever experienced and it tempting to hang on to such jewels, even for a while.  But don’t, let go and be grateful you did not spoil these treasures.  Our fear should not be of loss but of never finding within ourselves or others the treasures that certainly lie within all of us.
