Gems, especially colored gems, have been developing in the domestic market for a short time, and there are few data on the preservation and appreciation of gems.

Coincidentally, some time ago, I saw the statistical chart of the price trend of seven kinds of American national gems from 1975 to 20 18.

Colorless diamond (1 carat, D color, transparent, round)

Pink diamond (dark pink, 1 carat, contrast clarity, round)

Burmese ruby (1 carat, plum clarity, no burning sensation)

Burmese sapphire (1 carat, clear plum, no burning sensation)

Colombian Emerald (1 carat, plum clarity, no oil)

Brazilian Pale NBR (1 carat, blue, low temperature)

Burmese spinel (1 carat, red, plum clarity)

Let's analyze this chart,

1. experienced the ups and downs of 75-85, and the price of diamonds basically changed little.

2. pink diamond: 76- 18, 15000-200000, 43 years, 13 times, if calculated from 85 years, 73750 to 200000, 33 years, 2.7 times.

3. Ruby: 75- 18, 2500-60000, 24 times in 43 years, 85- 18, 12000 to 60000, 5 times in 33 years.

4. Sapphire: The growth curve is similar to that of ruby. After all, they are all good brothers of corundum family. 75- 18, from 800- 16000, 20 times in 43 years, 85-18,4500-16000, 3.55 times in 33 years.

5. Emerald: 1985-95 broke through the bottleneck and soared all the way until 15 or so. 75-18,3000 rose to 30,000, which increased by 10 times in 43 years. In the 33 years from 1985 to 18, the increase reached 50%.

6. Paraiba: The most terrible growth is Paraiba. Since the introduction of 1990, it has risen from 1 USD to 65,000, which has increased by 65,000 times in 23 years. Even if it is late, it will enter the market in 2008, and it will be17,500 to 65,000, which is 3.7 times that of 10.

7. Spinel: 75-18,200-6000,30 times in 43 years, 90-18,2467-6000,2.4 times in 28 years.

Note: 1. The above gemstone grades are indicated, and the specific varieties are of good quality.

2. The quality of diamonds and precious stones in the picture is GIA and AGL standards, and the prices refer to the retail price in the United States, which is not completely effective and accurate.

3. The unit is settled in US dollars.

After analyzing this curve, we will use this data to analyze the characteristics of these gems and why there are such price changes.

1. Diamond: Similar to gold, diamond is hard currency, and many people are debating whether to keep the value of diamond or gold. In fact, if the time axis is lengthened, gold, like diamonds, is not a good investment, and they can only be regarded as an internationally recognized "currency". Judging from the increase, it is actually similar, except that in China, gold is better to sell than diamonds, and there are more recycling institutions.

2. Red, blue and green: all belong to traditional gems, one of the five major gems, which have a very deep cultural heritage in the West and are deeply loved by the market. In addition, gems are non-renewable resources, and there are fewer and fewer high-quality gems, among which

2. 1 Gumu, Myanmar is a famous ruby producing area. Most rubies on the market have been heated and optimized to improve their color, so unburned rubies are especially rare.

2.2 The sapphire of Myanmar ancient animal husbandry is similar to ruby, with a well-known origin and no burning happiness.

2.3 Colombia is the most famous emeralds producing area in the world, and emeralds are developed with fissures, and the purity is L 1. Oil-free emeralds are rare.

3. Paraiba: Paraiba tourmaline was discovered in Paraiba, Brazil in 1988. It is a very special tourmaline, rich and neon-gorgeous green and blue, almost unique among all gems, very attractive, but its output is very rare. With the exploitation of vein resources, Brazil's mineral resources are almost exhausted and rarely appear in the market.

4. Spinel: a rising star in the field of gemstones, comparable to the color of ruby, hardness 8, glass to semi-metallic luster, extremely high-quality gemological properties, even rarer than ruby. Because there is no independent mining area and no mass production, large carats are extremely rare.

To sum it up

The investment and preservation of jewelry is actually the same as other logics. The risk of rising is also great, and the risk of rising is also small!

Hard currencies such as diamonds and gold will not rise or fall too much.

The traditional four precious colored treasures have more investment value than diamonds, with small output, unique origin and stable increase. If the budget is not enough, you can choose the newly rich gem producing areas, such as Mozambique ruby and Madagascar ruby, which are close to the people and have more room for growth. But the premise is good quality.

Relatively new gem varieties must meet the characteristics of beauty, durability and rarity before they have appreciation potential. For example, Paraiba has an extremely beautiful color. At present, there is no other gem to replace, such as spinel, which has extremely high-quality gemmological characteristics and rare output. This kind of gem often has a considerable price increase.

Such as pearls and amber, the output is too large, the hardness is too low, the gemological properties are not good enough, and the appreciation potential is often not very good.

10%-20% investment is enough, never more.

Here is a short story to help you better understand the appreciation of jewelry investment:

This story is about a doctor from GRS. 1980, a 32-carat Burmese ancient animal husbandry ruby was bought by a German for $200,000 and sold to an American jeweler for $425,000.

Later, this gem was finely cut and made into a 25-carat red gem ring, which was sold to a member of the royal family in the Middle East for $5 million.

In 20 15, this ring appeared at Sotheby's in Geneva, and was finally sold for 30 million dollars.
