Diamond & Quantum Weekly | Aug 3–9, 2026

Weekly signal

No strong theme of rapid volume growth emerged for CVD diamond materials or MPCVD equipment during August 3–9. Several widely circulated items referred to earlier projects or capacity plans, while others lacked a traceable original source. None could be upgraded to a new production, equipment-delivery, customer-order, or qualification milestone for the week.

The clearer incremental signals came from diamond NV-centre quantum sensing applications. CIQTEK’s Shanghai STAR Market IPO reached the allotment-results stage, and the third Diamond Color-Centre Quantum Sensing Instrument Applications Workshop was scheduled for August 7–9 in Hefei.

Together, these events provide visible examples of engineering and capital-market activity around NV-centre precision measurement. They do not show that the wider CVD diamond material industry has entered volume growth.

CIQTEK’s IPO reached its closing issuance stage

CIQTEK announced allotment results on August 4 for an offering of 40.01 million shares at RMB 21.22 per share. Its product portfolio includes scanning NV-probe microscopes, wide-field NV microscopes, and other scientific instruments based on diamond NV-centre quantum precision measurement.

The company offers a useful public-market case for following the path from laboratory physics to instruments, customers, R&D spending, delivery, and financial disclosure.

The boundary matters: CIQTEK is not an NV-only company. Its business covers multiple scientific-instrument categories, so IPO progress cannot be translated directly into large-scale profitability for its NV products.

The Hefei workshop broadened the application discussion

The University of Science and Technology of China School of Physical Sciences and CIQTEK jointly organized the third Diamond Color-Centre Quantum Sensing Instrument Applications Workshop at Hefei Quantum Instrument Valley on August 7–9.

The agenda included new color-centre preparation and control, quantum magnetic imaging, material characterization, semiconductor-chip inspection, and domestically developed quantum-sensing instruments. This is a broader engineering agenda than color-centre physics alone.

The event is evidence of application interest and technical exchange. It is not evidence of orders, revenue, or volume shipment; any new engineering parameters or application cases require post-event public material.

CVD diamond and MPCVD

No new event met all three requirements for inclusion: a traceable original source, an event date inside the weekly window, and verifiable key facts.

This does not imply that equipment, material, or customer projects stopped. It means that public evidence did not support a new high-confidence milestone for MPCVD batch delivery, formal CVD-line commissioning, thermal-management volume orders, or named customer qualification.

Event watch

The 36th International Conference on Diamond and Carbon Materials is scheduled for August 30–September 3 in Donostia–San Sebastián, Spain. Its scope includes diamond power electronics, sensing, defects and color centres, and quantum applications.

The second ASPIRE DiamondQTech technical workshop is scheduled for September 24–25 at OIST in Okinawa. Its abstract deadline fell on August 9, and its focus is practical training in diamond quantum technologies.

What the evidence says

The week’s most useful contrast was between two levels of evidence maturity. Material and equipment discussion still contained many plans, retellings, and unnamed customers. NV-centre quantum sensing, by comparison, showed a more continuous chain of product specifications, application examples, specialist meetings, and public financial disclosure.

The better conclusion is that diamond application routes are commercializing at different speeds, not that the entire industry is accelerating as one market.
