The electronic watch is black, the strap is made of rubber, ten small holes are evenly arranged on it, the strap is delicate and smooth, and it is very comfortable to touch.

This watch is not an ordinary style at first glance, how can a watch that can be invisible can be owned by ordinary people.

The round dial is covered with a piece of transparent glass, and two sparkling "diamonds" are embedded in the dial.

Luoyang wiped his watch, then blew his watch, with a smile on his face, he was a little excited in his heart, he didn't expect that the dirty box contained such a good thing.

When I was a child, the best thing I picked up was my wallet, which contained a wallet with more than 100 star coins, and at that time, the more than 100 star coins solved the family's expenses for half a year, and the wallet solved the urgent need, making their situation much better.

Luoyang was wearing a watch, the watch was shining in the light, shining brilliantly, the watch in his hand was noble and elegant, and the small diamonds were flashing.

"This should be a real diamond."

Luoyang pondered for a while, carefully looked at the diamonds on the watch, then opened the lid of the watch, took out a very small part of the diamonds, he removed the diamond, and then used a magnifying glass to magnify, the magnifying glass has a time limit, only three minutes, he identified whether the diamond is real or fake, if it is true, then, this watch can be sold for a very high price, even if it is very low, it can be sold for a lot of money.

The friction method can determine the authenticity of a diamond.

Natural diamonds are very hard and also very tough.

Therefore, if you use a piece of rough sandpaper to polish the surface of the diamond vigorously, there will be no scratches, on the contrary, the surface of the synthetic diamond is more likely to leave scratches.

It just so happened that he picked up sandpaper, and picked up a large piece of sandpaper.

Luoyang experimented for a while, and quickly identified the results.

This diamond should be real.

The weight of a diamond is measured in carats.

One carat (ct) = 0.2 grams (g), the size of different shapes of carat diamonds also varies, if it is a round carat diamond diameter is about 6.5mm. Diamonds are very rare, generally not large, and diamonds larger than one carat can be used for investment and have a certain ability to maintain and increase their value.

The price of a diamond is determined based on its weight, color, clarity and cut.

The price of a diamond is determined according to the merits of the 4Cs.

Generally speaking, if it is a one-carat diamond of average quality, it is between 20,000 and 30,000 star dollars; The quality is slightly better, around 60,000 Star Coins; That's really good, it's basically the price of hundreds of thousands of star coins.

"North to south, let's go, I picked up a good thing, a good thing that can make us rich."

Luoyang said, shouting Bei Yinan over there, he didn't intend to hide this matter, Bei Yinan saved his life, he would treat others as others treated him.

The person who drips water repays with the spring.

He had already decided to repay it with the rest of his life, if it weren't for her, he would have been poisoned and killed at the moment.

If you sell this watch at a low price, you can exchange it for a lot of star coins, take her to the hospital for a check-up, and completely remove the snake venom on her body.

"What's wrong?"

Bei Yinan was very confused, she stood on a high place and looked at the people below, and shouted loudly, what did he tell him to do, but he didn't see that he was trying to pick up garbage and make a fortune.
