Brilliant Diamond Exchange overview

A summary of what we're building. This isn't an offering document. Only offering circulars and private placement memoranda describe the terms and risks of an investment.

Summary

Brilliant Diamond Exchange (BDE) is a provenance registry and an ownership platform for the world's rarest natural colored diamonds. We record important stones on the Hedera network, and we offer shares in a few of them, each with its own market. Public offerings run under Regulation A, Tier 2, and private offerings to accredited investors under Rule 506(c).

The asset

Natural fancy colored diamonds at the top of the market: GIA-graded Fancy Intense, Vivid or Deep stones in pink, red, purple, blue or green, worth $1 million or more, each with a documented story. Lab-grown diamonds have made ordinary stones cheap. We think that makes proven natural rarity worth more.

Provenance registry

A permanent record for each important stone: its GIA report, laser inscription, history, custody and ownership, time-stamped on Hedera. Dealers, auction houses, insurers and collectors pay to register and verify stones. The registry isn't an investment product.

Structure

Each offered stone has one token on Hedera, divided into shares that represent fractional ownership of the stone. Brilliant Diamond Exchange DAO LLC stores and insures each stone in a secure vault and holds it for the token holders under a custody agreement. Each stone is appraised independently.

Markets and fees

Each stone's shares trade on a registered trading venue between verified wallets, with no fixed sale date. Anyone who acquires more than 50% of a stone's shares can require the other holders to sell at the same price. BDE earns a small fee on each trade, plus registry fees. It charges no issuance fee, annual management fee or profit share.

$BDE

Each $BDE token is a membership interest in Brilliant Diamond Exchange DAO LLC, with a maximum supply of 1,000,000,000. Holders own the company, vote on Exchange Improvement Proposals, can stake $BDE for a 7.5% annual reward paid in $BDE (guaranteed for the first five years from a 150 million token reserve), and receive distributions from company revenue under the policy in the offering documents. Distributions aren't guaranteed. A further 15% of supply is a regulatory and compliance reserve held by the DAO.

Offerings and compliance

Public offerings follow Regulation A, Tier 2: an SEC-qualified offering circular, audited financial statements, investment limits for non-accredited investors, and ongoing SEC reports. Every investor passes KYC, AML and sanctions checks.

Risks

Investing involves significant risk, including the loss of your entire investment. Read the risk factors.
