  • 01.Traceability
    PURE DIAMONDS differ from conventional diamonds in terms of transparency of transactions. This is thanks to the introduction of blockchain technology and implementing technology that ensures the reliability of diamond of PURE DIAMOND Network. From this, risks like purchasing fakes can be minimized.
  • 02.Platform
    It is possible to sustain the value of an actual lab-grown diamond due to appraisal data and transaction records’ associated network as well as present this information to users in an easy-to-understand format.
  • 03.Profitability
    The value of cryptocurrencies such as Bitcoin and Ethereum are supported by the consumption of electricity through mining. Because the power consumption and the value of the virtual currency are not linked however, there is a lack of stability in its value. However, in PURE DIAMOND COIN, it is not dependent on mining. It is possible to maintain a stable value and profit because the token is issued in concurrence with the value of a real lab-grown diamond.
  • 01.System
    PURE DIAMOND Network uses blockchain technology and implements encrypted P2P on the network. Therefore, it doesn't depend on the central control management and functions as a non-centralized type. It is possible to communicate equitably and distribute non-falsifiable information.
    Each PURE DIAMOND manufactured by PURE DIAMOND FARM is individually inscribed. PURE DIAMOND ASSET will be generated on PURE DIAMOND Network as data associated with a PURE DIAMOND DATA certificate and traceability.
  • 02.Blockchain
    PURE DIAMOND Network has studied new blockchain technology that is developing all over the world and actively implemented new technologies that is most appropriate for its properties in various aspects. We aim to build our own infrastructure that updates and improves constantly. Also, by developing an original blockchain, it becomes possible to build an original recognition algorithm, which enables us to calculate an actual physical amount of PURE DIAMOND and assigning revenue according to the mined amount. Real mining of this kind will become possible.
  • 03.Token Economy
    By PURE DIAMOND COIN − a cryptographic token that is built on PURE DIAMOND Network − PURE DIAMOND Token Economy will be created.In this way, an actual red diamond, which is prized for their rarity, or a new rainbow diamond can be grown. This potential can give birth to a new Token Economy that never existed before. In addition, we aim to use PURE DIAMOND COIN actually in the real world as a mode of settlement for goods or services on the Network.
  • 04.EXCHANGE
    PURE DIAMOND Token Economy will become the driving force of the economy through the sustainable circulation of PURE DIAMOND COIN. As the market to promote the distribution of PURE DIAMOND COIN, PURE DIAMOND EXCHANGE will open in order to trade PURE DIAMOND COIN. The exchange can be done so independently from us as PURE DIAMOND EXCHANGE works as a Decentralized EXCHANGE (DEX) system. Asset outflow doesn't occur in conventional centralized exchange through hacking because of high transparency safety.

FAQ

What is PDC?
Pure Diamond Coin is a cryptocurrency that is used for the purchase of lab-grown diamonds that cultivated from the Pure Diamond Project.
What are Lab Grown Diamonds?
Lab-grown diamonds are diamonds cultivated or ‘grown’ from a 100% pure carbon material in a controlled environment. They share identical chemical, physical and optical properties with natural diamonds allowing them to be certified by the Gemological Institute of America (GIA) recognizing that they are indeed diamonds in their own category.
What are the values of Lab
Grown Diamonds in the market?
The market for lab-grown diamonds are expanding at an unprecedented rate, it is estimated that by the year 2020, the market will be approximately 5 times bigger.
Why does it need to be a cryptocurrency?
We use our own cryptocurrency (PDC) to regulate the lab-grown diamond market because it enables us to implement blockchain technology. In short, it provides security and transparency offering consumers with peace of mind, exchanging lab-grown diamonds with full knowledge of its origin, quality etc.
You are the first company in Japan to utilize this technology, but there are also other competitors that are manufacturing lab-grown diamonds, what makes your company stand out?
There exist other competitors yes, but we are currently applying for a patent for our advanced technologies. What sets us apart from the rest of the competition is the fact that we implement blockchain technologies, ensuring security and transparency across all stages of the pipeline. This digital portfolio is then given to the end-consumer adding value to their purchase as are provided with additional information such as the origin, birth-date quality etc.
What is the difference between
PDC and other cryptos?
What sets Pure Diamond Coins (PDCs) apart from its competitors is the fact that it is associated with a ‘real asset’. Most cryptocurrencies are distributed without the consumer ever seeing the physical/tangible product. The fact that PDCs value is ‘pegged’ onto a collateral, Japanese lab-grown diamonds, achieves a more stable price for the token. Moreover, as more lab-grown diamonds are produced, the value of PDCs will inevitably appreciate, making this cryptocurrency very competitive and attractive to consumers.
Why do you need ICO?
The initial coin offering (ICO) is used to fund R&D and invest in capital to ensure a sustainable and steady generation of lab-grown diamonds.
Where is laboratory located?
Due to the fact that our laboratory is the first of its kind, this information is strictly confidential. So, we are unable to provide you with specifics.
What is the max supply?
The total number of all Pure Diamond Coins (PDC) tokens issued is the total number of token sale participants at the end of ICO. We set the total issue upper limit as 150% of all tokens.
Will PDC be listed on other
Exchange after ICO?
We are negotiating with several exchanges.
Do you have a bounty or referral campaign?
Yes, for more bounty information please follow this link: https://purediamond-ico.com/bounty/
Referral program is coming soon as well.
Why is there such limited information available on the White Paper?
This is due to the fact that all information we provide must undergo qualified legal checks, more information will be updated in due course so be sure to check back regularly.
How can I participate in the pre-sale crowd-sale?
You can participate in the initial coin offering (ICO) by following this link here: https://pd-coin.io/login
Are there minimum and maximum purchases?
Our minimum purchase is 1000 PDCs. We do not have a maximum limit on how many tokens. you can purchase.
What is your ICO schedule?
Pre-sale SEP.1 - SEP.25 | 1PDC = $0.12 equivalent
Phase 1 OCT.5 - OCT.30 | 1PDC = $0.16 equivalent
Phase 2 NOV.5 - NOV.30 1PDC = $0.21 equivalent
Which currencies and wallets do you accept?
To purchase Pure Diamond Coins (PDCs), we accept BTC, ETH, BCH, ETC, and any wallets compatible with ERC-223/ERC-20 tokens.
Are there any countries exempt from participating in the ICO?
No. All participants from all countries can participate in the ICO.
When is the token distribution?
PDC token distribution will be implemented during DEC 15 - DEC 31
What wallet types are compatible with PDC?
Pure Diamond Coins are an ERC-223 type-token. ERC-223 tokens are backwards compatible with ERC-20 tokens, which means that any wallet that can accept or are compatible with ERC-20/223 type tokens can accept PDCs. An example of a wallet that is compatible with ERC-20/223 tokens is MyEtherWallet (MEW).
Why would the value of PDC increase?
This is due to the nature that there is a limit to the number of PDCs in circulation, and because PDCs are used exclusively to purchase and exchange lab-grown diamonds. As the demand for lab-grown diamonds increase, so does the demand for PDCs, and because there is a limited number of PDCs in supply, the price will gradually increase with demand.
