CVD Single-Crystal Diamond Seed–Rough Blank
Product Details
From Seed Crystals to Rough Blanks: The Starting Point for Diamond Applications
We provide key raw materials for every stage of CVD (Chemical Vapor Deposition) diamond growth, including uncut and unpolished CVD rough cubes (Rough Cube), CVD seed crystals (Seed Crystal) serving as the foundation for diamond epitaxial growth, and gem-grade CVD white diamonds (Gem-Grade CVD Colorless Diamond). This gives downstream customers a comprehensive supply of diamond raw materials ranging from industrial-grade to gem-grade products.
Core Product Overview
CVD Seed Crystal (Seed Crystal)
CVD seed crystals are the starting point for diamond epitaxial growth. Their lattice orientation, surface flatness, and cleanliness directly determine the quality and yield of subsequent diamond growth. We offer seed crystals in various sizes and sidewall orientation specifications. Customers can select standard sidewalls (100) or specific crystal orientations (110) according to their growth requirements. Certain specifications are also available with the four corners removed to meet the loading and growth requirements of different epitaxial processes.
CVD Uncut, Unpolished Rough Cube (Rough Cube)
CVD Cube is diamond rough material that has completed the growth process but has not yet undergone cutting, grinding, or polishing. It retains the original crystal structure from the growth stage, allowing customers to perform downstream processing—including cutting, grinding, and polishing—according to their specific application requirements. It is ideal for downstream users requiring highly customized cutting directions and dimensions.
Gem-Grade CVD White Diamond (Gem-Grade CVD White Diamond)
Gem-grade white diamonds grown using CVD technology have chemical and physical properties that are nearly identical to those of natural diamonds, with excellent clarity and color-grade performance. We offer gem-grade rough blanks in various sizes for jewelry cutting and polishing facilities to develop subsequent cutting designs and polishing processes according to market demand. These products are an important upstream source of raw materials in the lab-grown diamond (LGD) supply chain.
