  • 01.The Scale
    – Progressive Expansion
    The global demand for the natural diamond jewellery market is valued at approximately $83 billion USD in 2018. Pure Diamond’s lab-grown diamonds aims to disrupt this market by introducing the latest technological innovation to the jewellery industry.
  • 02.The Trend
    – Disruptive Technology
    Chartered Financial Analyst (CFA) Mr. Neri Tollardo for Morgan Stanley had published an article in which he expresses that “The hot topic within the diamond industry right now revolves around lab-grown diamonds”. The technology behind Pure Diamond’s lab-grown diamonds have now matured to the stage where it could potentially threaten the natural diamond trade.
  • 03.The Approach
    – Blockchain Based
    Pure Diamond’s approach, is to add value and enhance the customer experience for lab-grown diamonds. No other competitor, or lab-grown diamond manufacturer has implemented blockchain technologies to their product. Pure Diamond’s original blockchain network intends to store and build a non-falsifiable digital profile for consumers regarding their purchase. Which in turn also increases resell values and this portfolio protects unknowing consumers by presenting them with the true value of their lab-grown diamond in detail.
  • 01.Lab-Grown Diamonds
    Lab-grown diamonds are genuine diamonds that are grown in controlled laboratories that exhibit identical physical, chemical and optical properties as natural diamonds. They are not ‘imitation stones’ or substitute diamonds such as cubic zirconia or crystals.
  • 02.Environmentally Friendly
    Pure Diamond’s lab-grown diamonds solves the issues of emissions and sustainability by producing a consistent output with lower energy consumption. The process protects the geology of the landscape because it does not actually require physical excavating.
  • 03.Ethically Advantageous
    In developing countries, diamonds are mined during a time of conflict, and it floods the natural diamond industry with ‘blood diamonds’. Often miners which include women and children are forced to mine under extremely dangerous circumstances in mines. Lab-grown diamonds are cultivated inside a controlled facility, and therefore nullify the need for physical mining of any type, rendering them ethically better compared to natural diamonds.
  • 01.System
    The Pure Diamond Network utilises the latest blockchain technology, implementing a decentralised encrypted P2P network. The information of our lab-grown diamonds is communicated equitably with non-falsifiable information provided to the end consumer.
  • 02.Blockchain
    The Pure Diamond Network draws from leading blockchain technologies around the world and passively implements new technologies that is most appropriate for its properties in various aspects. We aspire to build our own infrastructure that updates and improves constantly. Through the development of an original blockchain, the implementation of an original recognition algorithm becomes possible, which enables us to calculate the true actual physical number of Pure Diamond’s lab-grown diamonds in circulation and assigning revenue according to the mined amount.
  • 03.Token Economy
    The Pure Diamond Coin (PDC) is a cryptographic token that operates on the Pure Diamond Network, creating a token economy for holders who wish to purchase lab-grown diamonds with PDC’s market price determined by third-party crypto currency exchanges. This allows both lab-grown diamonds and PDC to be exchanged and traded in their own separate markets respectively.
  • 01.Pure Diamond Coin
    The Pure Diamond Coin (PDC) is a cryptographic token that operates on the Pure Diamond Network, creating a token economy for holders who wish to purchase lab-grown diamonds with PDC’s market price determined by third-party crypto currency exchanges. This allows both lab-grown diamonds and PDC to be exchanged and traded in their own separate markets respectively.
  • 02.Token Stability
    Due to the nature that the Pure Diamond Coin’s (PDC’s) valuation is attributed to the distribution and demand of Pure Diamond’s lab-grown diamonds, it can ensure relative token price stability for the PDC.
  • 03.Pure Diamond Exchange
    The Pure Diamond token economy will become the driving force of the Pure Diamond project through the sustainable circulation of the PDCs. As the global demand of lab-grown diamonds increase, as too will the demand for PDCs to purchase these lab-grown diamonds, the Pure Diamond Exchange which is currently in development will open in order to trade PDCs.
    The Exchange will be opened independently from the project as the Pure Diamond Exchange works operates as a decentralised exchange (DEX). Asset outflow does not occur like conventional centralised control management exchanges, offering consumers a high degree of transparency and security.

    Market Trends
    The diamond industry trend is shifting gradually to lab-grown diamonds as the growing visibility and produciton capacity.
    Large companies such as De Beers are currently advocationg their new brand in lab-grown diamon product lines.
  • 03

    We store all information on an encrypted P2P network. Blockchain technology allows traceability and transparency on everything associated with Pure Diamond from Pure Diamond Farm.
  • 04

    Our diamonds are not 'synthetic', we researched for severl years and successed to recreate the rare generate conditions that are required for real diamonds .Under the controlled environment, real, true diamonds are generated.
    This is our 'Pure Diamond'.

Shigy Ishida

Mr. Ishida was appointed the Diamonds & Antwerp Ambassador from AWDC in Belgium and is an expert with a high degree of knowledge of diamonds. Ishida wanted to import more diamonds into Japan and had thoughts to import relatively inexpensive American lab-grown diamonds. However, he recalls of one time when he came across a Japanese-made lab-grown diamond and was shocked by its high quality. Since then, he began seriously considering the possibility of exporting this high-quality Japanese lab-grown diamond to the rest of the world.

Takuya Ito
Managing director

Mr. Ito is appointed Senior Managing Director, Pure Diamond Co., Ltd. Ito says he feels that there is a big possibility for inexpensive lab-grown diamonds to be as viable as natural diamonds as the former are of the same quality as the latter. Speaking of the diamond industry, in the past, those who wanted diamonds were unable to obtain them as they were simply too expensive. Since lab-grown diamonds are trading at half the price of natural diamonds, lab-grown diamonds have the potential to solve this issue. Ito holds seminars in a mission to distribute lab-grown diamonds and delivering diamonds to as many people as possible.

Jun Kawasaki

Mr. Kawasaki is a young engineer who was active as an ethical hacker and had even worked on the NEM cases. He says that this project provides him with less security. Unlike traditional diamonds, introducing blockchain technology increases the transparency of trading and minimises the risk of buying fakes. Information is recorded on the P2P network via encryption using blockchain technology. By functioning as a decentralised ledger, fair and unimpressible communication becomes possible. Unlike natural diamonds, it is possible to say that the risk of buying fakes is small, and as such, the risk of fraud is small too.

Grant Yim

Mr. Yim is the marketing and technical advisor for the Pure Diamond Project board. A newcomer to the blockchain and cryptocurrency industry, Grant has amassed diverse experience from the Jewellery Industry and e-commerce related businesses. He is currently the CEO of the RS20 Group, a Hong Kong based marketing solution firm. Mr. Yim holds a bachelor’s degree in Law, graduating from the University of Exeter in Devon, United Kingdom in 2017. He brings practical legal and business professionalism to the Pure Diamond Project.

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:
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:
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.
