Economy Grade CVD Diamond Seed Plates
Discounted CVD diamond seed plates for process development, R&D testing, operator training and low-cost diamond growth experiments.
These seed plates are supplied from available inventory and may contain cosmetic, dimensional or orientation-related imperfections that do not meet standard commercial grading requirements. They provide a cost-effective option for applications where perfect seed quality is not essential.
Each lot is evaluated individually, and stock photos can be provided before shipment.

Typical Applications
Economy grade seed plates are commonly used for:
CVD growth trials
Process development
Parameter optimization studies
Surface preparation testing
Cleaning and pretreatment evaluation
Laboratory training
Equipment commissioning
Educational and research projects
Non-critical diamond growth experiments
Why Choose Economy Grade Material?
For many development-stage projects, the primary objective is process verification rather than maximum crystal quality.
Economy grade seed plates can significantly reduce material costs during:
Early-stage process development
Equipment setup and qualification
Operator training
Experimental growth parameter studies
Proof-of-concept research
Using lower-cost seed material during these stages can help reduce development expenses before moving to production-grade substrates.
Condition and Inspection
Because inventory varies, defect type, location and severity are not identical for every piece.
Available information may include:
Visual inspection photos
Approximate usable area
Surface condition notes
Orientation information (when available)
Lot-specific comments
Customers with specific requirements for orientation, defect density or surface quality should discuss these requirements before ordering.
