Dig-Dig #15: Follow Up Part 2

Heat treating brought out the colours, and cutting/faceting gave them the sparkle. It's hard to explain how happy Aya is with these results.

The stones were cut to whichever shape allowed the least loss. "Princess" cut is square (-ish).




What is amazing is that there is another batch still to come.
The next step is to start panning gold here in BC and eventually (hopefully) collect enough to make something that will hold these.

Dig-Dig #14: Follow Up

The postman brought a strange package today.
Her heart rate was tracked.


What...  what is this?

Phillipsburg? Wha-? AH! Is it?

Come on...

Is it really?

Oh, come on!

Stupid plastic... Scissors. SCISSORS!

Oh, COME ON!

Eeeeeeee!

Garnets

We loved picking sapphires out of the Montana gravel so much that we brought back a bucket-load to search through at home. That will occupy a few autumn evenings while we wait for the big ones to come back from the cutter.

We also bought ten pounds of Zambian gravel in which supposedly lurks a garnet or two. They say you are guaranteed to find at least one garnet in each bag.

Aya dished out a bowl-full, washing and swirling over the balcony wall.

Muddy stone soup.

There, that dark, glassy one in the lower middle right.

Okay, that's impressive.

Don't believe it's really that easy? Watch Chris, the very friendly owner of Gem Mountain, demonstrate the wash routine:



And now the flip:

Dig-Dig #2: Sapphires in Montana

Google Maps link to Gem Mountain.

Arriving at Gem Mountain in the late afternoon, we set up camp and made a great big dinner of pork cutlets and a Beringer White Merlot. It is hard to go wrong making a bright, flavourful rosé from well-ripened grapes, but this is where Beringer shows real determination. We can recommend this wine if you like sugar and hate your tongue. The pork was excellent, however, and we fried up some extra for the next day's sandwiches, hoping to eat them from a gunny sack by the crick, or something equally rustic.

Aya could hardly sleep in anticipation of the next day's activities: pulling raw sapphires from the pure Montana dirt.

Here's how it works:

You buy a bucket of alluvial gravel.

Pour a manageable amount into your screen.

Take the screen of dirt to the washing trough, which is filled with warm Montana river water. One of those adjectives is not accurate.

Using the two washing techniques demonstrated by the Gem Mountain staff, get the small pebbles to the center and the larger ones to the outside edge in a circular pattern. Heavier sapphires will sink to the bottom.

Flip the screen over in one smooth motion.

There. There. There and there. At least four sapphires of different colours in this batch. Did you know that rubies are rare red sapphires?


Sunday afternoon at Gem Mountain.

We looked through seven buckets of gravel before taking our collection into the office to have them assayed. A total of 95.56 carats on the first day!

First the sapphires are sorted by size.

Those above a certain size and without flaws are considered "cuttable". Heat treating will enhance the colour.

Anticipation.

The first day's cuttable sapphires, averaging almost one carat each.

We only went through three buckets of gravel in the morning of the second day but managed to find almost as many as the day before. Only one less cuttable gem and another eight that are "flawed but cuttable". We left them all to be heat treated and cut into whatever shape best suits each one. They'll show up in the mail in a few months after we have forgotten about them, bringing joy into a rainy winter's day.
