1What is pink diamond? history and rarity
First, let's understand why pink diamonds are attracting so much attention - the basis for their rarity.
Why pink diamonds are said to be rare
Fancy colors (other than colorless) account for a small percentage of all diamonds.Approximately 0.01%. Furthermore, among these, pink diamonds are produced in extremely small quantities, and are the only diamonds mined in the world.Pink percentage is less than 0.001%It is said.
Unlike colorless diamonds, which take on a yellowish tinge due to nitrogen impurities, the mechanism by which pink color develops has not yet been completely elucidated. The prevailing theory is that it is caused by "plastic deformation," but the fact that it is a chance product that occurs deep in the earth makes it even more rare.

Main production areas and the impact of the closure of the Argyle Mine
pink diamonds of the worldApproximately 90%was produced in western Australia.Argyle Mine (Rio Tinto)It is. The mine was closed in November 2020, and new supply has almost ceased.
1983
Argyle Mine begins commercial mining. Supporting the world's supply of pink diamonds.
2000s~
Output decreases as the vein deepens. Only a few dozen pink diamonds over 1 carat are produced each year.
2018
Rio Tinto officially announces the closure of the mine at the end of 2020. The outlook for price increases strengthens in the industry.
November 2020
Argyle mine closed. It brings down the curtain on a 37-year history.
2020-present
After the mine closed, the transaction price of pink diamonds at auctions and secondary markets has been on the rise. The rise in prices of high-quality products is especially noticeable.
What are the production areas other than Argyle?
Brazil, Tanzania, Russia, and India also produce a small amount of it, but it is not on a scale that can be called a stable supply. Many of the pink diamonds currently in circulation are stock mined before the mine was closed. It is expected that the amount on the market will continue to decline unless new large-scale deposits are discovered.

2Factors that determine the value of pink diamonds
The value of regular diamonds is determined by the 4Cs (Color, Clarity, Cut, Carat), but for pink diamonds,“Color” is overwhelmingly importantIt is. Here we will explain the three axes that influence value in order of priority.
color depth and tint
What has the biggest impact on the price of pink diamonds?"Saturation/Tone"and“Purity of color (Hue)”There are two.
① Color intensity: GIA grade system
GIA (Gemological Institute of America) evaluates the intensity of fancy colors on the following nine levels. "Fancy Vivid" is the most expensive pink diamond, and the price decreases as it approaches "Faint."
Fancy Vivid maximum saturation
Fancy Deep deep hue
Fancy Intense strong color saturation
Fancy enough color
Fancy Light somewhat pale
Light pale
Very Light quite pale
Faint Honoka
② Purity of Hue: Pay attention to modifiers
The color name listed on the certificate of authenticity may have a ``modifier'' before the main color. This modifier greatly affects the price.
Pink
(pure color)
(pure color)
Purplish Pink
Orange Pink
Brownish Pink
Brown Pink
| Color notation | meaning | Impact on price |
|---|---|---|
| Pink (no modifier) | pure pink. most popular | highest |
| Purplish Pink | Purplish pink. A gorgeous impression | expensive |
| Orange Pink | orange-pink | slightly lower |
| Brownish Pink | brownish pink | downward trend |
| Brown Pink | Brown is the main color and pink is the secondary color. | drop significantly |
Key point: You can tell who is the master or slave by the position of “-ish”
“Purpl.ish Pink" → Main color is pink (mainly pink with a tinge of purple)
"Pinkish "Purple" → Main color is Purple (mainly purple with pink tinge)
The color that comes after is the "main color". When looking at a certificate, be sure to check this word order.
Which should I prioritize: carat or color?
When purchasing pink diamonds, many people worry about whether to choose a large, light-colored stone or a small, dark-colored stone.
Example A: 0.40ct/Fancy Light Pink
The size looks great.
However, the color is quite pale,
It may be difficult to tell the difference from the white diamond.
VS
Example B: 0.18ct/Fancy Intense Pink
The grains are small but the colors are bright.
It has a strong presence of “pink diamond-ness”.
You can make up for it with your entourage.
Conclusion: Pink diamonds are all about color.
If you get lostStones with a higher color gradePrioritizing is the choice you will not regret.
If you get lostStones with a higher color gradePrioritizing is the choice you will not regret.
For colorless diamonds, "size = impact" is important, but for fancy colors,Beauty and vividness of colors are the center of valueIt is. In the actual market, it is not uncommon for 0.2ct Fancy Intense Pink to have a higher unit price (price per 1ct) than 0.5ct Fancy Light Pink.
When making a ring or necklace, by adding melee diamonds (small white diamonds surrounding it), you can create a gorgeous look even if the center stone is small.The power of design can compensate for “apparent size”However, the intensity of the color cannot be changed afterwards - if you use this point as a criterion, it will be easier to compare candidates.
Importance of appraisal report
The point where you are most likely to fail when purchasing pink diamonds isInsufficient confirmation of appraisal report (grading report)It is. Even if a stone is labeled as "pink," the same stone may be rated differently depending on the issuing agency and grading standards.
📋
GIA
The world's most reliable appraisal agency. Strict standards for fancy colors. Stones with a GIA certificate are more likely to be valued at resale.
📋
CGL (Central Gem Laboratory)
The most experienced appraisal agency in Japan. CGL certificates are the mainstream for domestic sales. Although it is generally consistent with GIA, there may be slight differences in color notation.
- Color Grade:Check the official names of "intensity + color" such as Fancy Intense Pink
- Color Origin:Does it clearly say "Natural"? Possibility of treatment if not listed
- Carat Weight:Check to the second decimal place
- Clarity:VS or higher is desirable, but for fancy colors, priority is given to color and SI level may be acceptable.
- Appraisal organization name:Is it a highly reliable institution such as GIA or CGL?
Important note: “sorting” and “certificate” are different things
"Sorting" is a simple sorting document and is different from a formal appraisal report (grading report). Be sure to use this for purchases over several hundred thousand yen, as the effectiveness may be weak during resale and insurance appraisals.Comes with official certificateLet's make sure that it is.

Natural pink diamonds over 1 carat are Fancy Intense and above.Tens of millions of yen to hundreds of millions of yenIt will be a world of This is an area that is traded at auction houses (Christie's, Sotheby's, etc.) and is very different from the general budget for purchasing jewelry.
Tips for checking whether the asking price is reasonable
In the case of finished jewelry, consider how much of the price is the value of the center stone, and how much is the base metal, diamonds, and design processing costs.
Example) “0.25ct Fancy Pink ring 550,000 yen”
├ Ruth estimate: 250,000 to 400,000 yen
├ Pt900 bullion + melee diamond: 80,000 to 150,000 yen
└ Processing/design fee: 50,000 to 100,000 yen
By breaking it down in this way, it becomes easier to judge whether there is a large discrepancy in prices. If you are unsure, we recommend that you get a quote for the loose piece first and then check the framing cost separately.

4Difference between natural pink diamonds and treated/artificial diamonds
There are three types of stones sold as "pink diamonds": natural, treated, and lab-grown. Let's learn about the characteristics of each and how to tell them apart.
Characteristics of natural pink diamonds
🌍
Natural
Naturally produced in the high temperature and high pressure environment inside the earth. The color is caused by distortion of the crystal structure. Items that have not undergone any artificial processing other than cutting and polishing after mining. "Natural" is written on the certificate of authenticity.
🔬
Treatment (processed)
A natural diamond that is originally pale or brown in color has been given a pink color through HPHT treatment or irradiation treatment. The raw stone is natural, but the color is artificially altered.
🏭
Lab-grown (artificial synthesis)
Diamonds grown artificially in factories using CVD or HPHT methods. Chemically, it is just like a diamond, but its structure is different from that of natural diamonds, and its rarity value is difficult to recognize.
The biggest feature of natural pink diamonds isThere is a physical limit to the amount mined.Things. After the closure of the Argyle Mine, market stocks will continue to decline unless a new source of supply is found. On the other hand, treatments and lab-grown products can theoretically be mass-produced in any quantity, so it is currently difficult to expect prices to rise due to scarcity.
How to distinguish between treatments and artificial diamonds
| Item | natural | treatment | lab grown |
|---|---|---|---|
| Statement of appraisal | Natural | Treated / HPHT / Irradiated | Laboratory-Grown |
| rarity | extremely high | low | low |
| asset value | expensive | low | Almost none |
| Price level (compared to same color grade) | Standard (100%) | Approximately 10-30% | Approximately 5-15% |
| Visual discrimination | Difficult. Must be confirmed with a certificate | ||
STEP 1: Check the “Origin” column of the certificate of authenticity Check to see if it says "Natural". If it is not listed, please check with the seller.
STEP 2: Check the reliability of the appraisal agency Is it issued by an organization recognized as reliable in the industry, such as GIA, CGL, or AGT?
STEP 3: Beware of “low prices that are far from the market price” If it's natural Fancy Intense Pink but surprisingly cheap, you should suspect that it's treated or lab-grown.
STEP 4: If you have any concerns, request a re-examination It is also an effective method to request a re-appraisal from GIA or CGL (or check with the seller if this is possible) before purchasing.
Treatment and Labo Grown are not “bad”
If you want to purely enjoy the beauty of your appearance, treatment and lab-grown pink diamonds are also options. However,When expecting future asset valueYa,If you find meaning in being “natural”Please be sure to check the certificate for Natural. The biggest cause of regret is buying something without knowing.

5Do pink diamonds have asset value? Thoughts on future prices
“The price of pink diamonds will rise.” How grounded is this statement? Organize the facts and points to note.
Reasons why prices are said to rise
⛏️
supply shrinkage
Due to the closure of the Argyle Mine, new supply will be reduced to almost zero. The only stones available on the market are "inventory", which decreases over time.
📈
Expansion of demand
Interest in fancy colored diamonds is increasing year by year, especially in Asia (China, Japan, and South Korea).
🏛️
Auction results
High-quality items continue to reach record high prices, such as ``The Ryu Pink'' (11.15 ct) being sold for $57.6 million in 2022.
In fact, in the five years following the closure of the Argyle Mine, the trading price of high-quality (Fancy Intense or higher) pink diamonds increased.Annual rate of 10-20%There is also industry data that shows that the market is on the rise. The structure that ``supply is irreversibly decreasing and demand is increasing'' can be said to be a rational basis for price increases.

Points to note when purchasing for asset purposes
Although there is a possibility of price increases, if you consider jewelry as an investment, you should understand the following risks and precautions.
Pink diamonds as an asset, 5 things to keep in mind
- Low liquidity:Unlike stocks and gold, it is not always possible to find a buyer immediately when you want to sell. Generally, the appraisal value of the purchaser is around 30-60% of the retail price.
- Retail price includes margin:Since the price at the time of purchase includes branding fees, design fees, and sales costs, ``even if you sell it the day after you buy it, you usually won't get your money back.''
- There is a wide range of color grading:Since evaluations differ slightly depending on the appraisal agency, there is a risk that the evaluation will be lower than expected upon resale.
- Storage and insurance costs:Since high-value items are at risk of theft or loss, you should also consider the cost of insurance and safe deposit boxes.

Finally
The value of pink diamonds is"Color intensity" → "Color purity" → "Carat"It is determined in this order. If you keep this order of priority in mind, it will be much easier to compare candidates.
Make sure that the appraisal is ``Natural'' and that it is issued by a reliable appraisal organization, and if it is a finished product, be aware of the breakdown of loose metal, bullion, and processing costs. Just by practicing these three things, you can turn your ``somewhat uneasy'' purchases into purchases you are ``satisfied with''.
With the closure of the Argyle Mine, natural pink diamonds will become increasingly difficult to obtain in the future. That's why, instead of choosing in a hurry,Determine the “correct answer” for yourself and then get it.That's important.
