The mine owners and miners of Lightning Ridge are not stupid, they are all people who have crawled out of rumors and deceptions, and it is not easy to get them to believe a piece of news. Pen "Fun" Pavilion www.biquge.info

However, regarding the relationship between Li Du and Blatche, people believe that it is not as rumored at the beginning, that Blatche cheated Li Du.

Because Li Du never troubled Brache, someone saw Li Du visiting Blatche with gifts, and Blatche received him and invited him to a big meal.

Everyone in Lightning Ridge knew what kind of bird Brache was, and if this thing was a trick, he would never receive this person, let alone invite the other party to a big meal.

So people began to wonder, is the news that came out true, Li Du really took the initiative to buy the shit mine in Blatche's hand and dug up the gem?

The day after visiting Brache, Li Du went to an ore cutting workshop in the morning, which had tools such as waterjets, angle grinders, and hand grinders, specializing in ore grinding.

When they entered the workshop, they were immediately greeted by employees: "Hello, everyone, do you need any help?" ”

Godzilla opened the box, revealing more than a dozen ores inside, and Li Du said, "Help me polish it and polish the gems inside." ”

He had already preliminarily polished it, and the figure of the black opal was faintly revealed.

Seeing the ores, the employee exclaimed, "So many gems? Gosh, you're in luck, you must have found a vein of black opal? ”

Li Du urged him: "Yes, my luck is good, a friend sold me a good mine. Hurry up, I can't wait to see these gems. ”

It costs a hundred Australian dollars to polish a piece of ore, and these add up to 1,200 pieces.

Li Du paid the money, and someone immediately launched the tool and guarded him and began to polish it.

Stripping black opals is complex and requires the use of a variety of tools.

The first is the water saw, which is a bit like a waterjet, but the process is simpler, using a chainsaw to cut, and the main process is cutting and rubbing.

The advantage of a water saw is that it is highly efficient, but the disadvantage is that it has a large cutting loss, is extremely dangerous, and is prone to accidents.

However, the staff who operate the watersaw are veterans and have a good grasp of this thing.

He picked up a piece of ore and placed it on the watersaw table, which is about a meter high, 60 centimeters wide and 80 centimeters long, and can be used to process thicker stone skins.

Flipping the switch, the watersaw splashed and spun rapidly, and the worker rubbed a piece of ore on it, and with a 'snort' noise, the ore fragments flew out.

The worker stared intently at the ore, and as soon as there was a slight trace of a gem in the ore, he immediately withdrew his hand and changed to another angle.

Li Du looked at it for a while and felt that the money was worth it, and it was rare for people to polish the ore but not hurt the gem at all.

There were also some miners in the workshop who were buying things, and when they saw someone polishing the gem, they came up with great interest, and as the water saw cut, the figure of the gem became clearer and clearer, and they exclaimed:

"A big treasure, Our Lady on top, I bet there are four criteria for its size."

"It's definitely a big baby, the color is so good, look at its color, even if there are no four standards, this guy is priceless!"

"Oh my God, why haven't I ever had such good luck!"

"It's not just good luck, man, it's a blast of luck! How long has it been since I've seen a brilliant gemstone like this? ”

As the watersaw cut off the edges and corners of the ore, the general figure of the gem was revealed, attracting more onlookers.

The twelve ores contained very good gems, and as the pieces were cut, exclamations rang out one after another.

After the water saw cuts, it also needs to be sanded with an angle grinder.

The angle grinder is the most common hand-held processing tool, which can be used to cut, grind, polish stone, and can also be used to peel black opal rough.

When using this tool, people can no longer get very close, the stone skin broken by the angle grinder is very small, and the splash is very large, and it is easy to damage the eyes.

After these two tools, the black opal is almost completely displayed, but there are other tools behind, such as the use of a dental machine for the final sweeping.

A dental machine is a common tool used by dentists with a very sensitive and small drill bit to maintain people's teeth.

The jewel tooth machine is the result of the modification of the human tooth machine, it has become more sensitive, with a small spring behind the drill bit, as long as the drill bit feels a change in pressure, it will retract.

Black opal is brittle, but it's harder than the rock that wraps around it.

As a result, the gemstone tooth machine can polish away the small pieces of rock that last adhered to it, without harming the gemstone itself.

A series of processes were completed, and pieces of black Oba in their original posture appeared in everyone's field of vision.

The number of gems polished at one time was so large that even the workshop owner was attracted to it.

After grinding, the boss carefully handed the black Oba wrapped in deerskin to Li Du and said, "Sir, please taste it, are you still satisfied?" ”

Li Du picked up the largest piece of opal, and the sunlight shone through the glass, and he put this gem into the sun, and suddenly, a dazzling light appeared.

The gemstone is based on a grayish-black body with blue, purple and crimson color changes, and the sunlight shines through the stone, and the different color changes shine differently.

Li Du slowly turned his wrist, and with the different angles of light, the color change combination also changed.

Someone exclaimed, "This is a real black opal, at least N2 level!" ”

Black opals are divided into nine grades, from N1 to N9, of which the highest grade is N1, and the highest value is also N1.

The N2 level is already very high, and the N1 level black opal is particularly rare, and Lightning Ridge may not be able to produce a piece for a month, and once it appears, it will inevitably encounter crazy robberies from gem dealers.

The gem in Li Du's hand will also cause gem dealers to rush wildly, it is N2 level, which is already a high level, and at the same time it is very large, which is very rare.

Turning this opal, the group showed a look of fascination.

And that's not what black opals really look like, just like diamonds, black opals need to be cut, and after cutting, they can show their most unique style!

Looking at each of the twelve gems in the sun, Li Du collected them.

Before he had even left the house, a gem dealer came to his door and asked, "Sir, are you interested in selling these gems?" I'm willing to give a good price. ”

Li Du asked, "What price?" ”

"N2 is a gem, I am willing to buy it for 500,000." A middle-aged man in the back scrambled to say.
