CZ Positive Identification Upgrade Announcement
New Upgrade Available:
CZ Positive Detection Mode
At DRC, our commitment has always been to keep our customers ahead of market challenges through reliable innovation and continuous technology upgrades. As the diamond ecosystem evolves, screening requirements are becoming more complex — especially with the increasing trend of CZ (Cubic Zirconia) being mixed with natural and lab-grown diamonds, particularly in smaller sizes and studded jewellery.
To support this industry need, we are pleased to announce the launch of a new upgrade: CZ Positive Identification Mode, now available for selected existing machine models.
What Is CZ and Why Is This Upgrade Important?
Cubic Zirconia (CZ) has been the world’s most widely used diamond simulant for over four decades. While CZ may appear visually similar to a diamond, it does not share the same optical, chemical, or physical properties.
In loose form, trained professionals may sometimes identify CZ by weight or reflection behaviour — but once stones are:
- Mounted in jewellery,
- Cut into melee sizes, or
- Mixed in large batches,
identifying CZ with the naked eye becomes nearly impossible.
For reliable separation, technology must now complement experience.
