Carbon Extraction Patent

BioGem Lab's proprietary carbon extraction and purification technology is protected under Chinese national invention patent ZL 2010 1 0565778.9, granted in 2012 (Certificate No. 1058820). The patent covers the complete process chain for extracting usable carbon from biological materials — hair, fur, and plant fibers — and purifying it to gem-quality synthesis standards.

This extraction protocol is the foundational differentiator in our manufacturing stack. It enables consistent carbon yield from diverse biological sources while maintaining the purity thresholds required for high-clarity diamond synthesis.

Growth Process Parameters

Catalyst System

Iron-nickel alloy catalyst with optimized carbon solubility. The catalyst dissolves the graphite source and precipitates diamond onto the seed crystal under controlled temperature gradient conditions.

Seed Crystal Selection

High-quality synthetic diamond seeds with minimal defects are selected based on crystallographic orientation. Seed quality directly impacts final clarity and color consistency. Read technical guide

Pressure Calibration

Hydraulic press systems with real-time pressure monitoring maintain 5.5 GPa ±0.2 GPa throughout the growth cycle. Pressure stability is critical for preventing structural defects and inclusions.

Thermal Gradient Control

The growth chamber maintains a controlled thermal gradient of 20–40°C between the carbon source and seed crystal. This drives carbon transport from the dissolved graphite to the growing diamond face.

Purification Pipeline

Carbon Extraction & Purification

The patented carbon extraction process transforms raw biological material into synthesis-ready graphite through a multi-stage purification pipeline. Each stage is monitored by spectroscopic analysis to ensure the 99.95%+ purity threshold is met before graphitization.
