原料甄选高纯原料，源头控瑕

Raw Material SelectionHigh-purity Materials, Source Defect Control

原料甄选 | 高纯原料，源头控瑕

Adopt 99.999% high-purity carbon & silicon raw materials with spectral sampling inspection. Impurity content is controlled below 1ppm, inferior industrial feedstock eliminated to avoid yellow tint, inclusion and crack defects fundamentally.

精选99.999%高纯碳、硅基材，仪器光谱抽检，严控杂质＜1ppm，淘汰劣质工业原料，从根源杜绝晶体发黄、杂色、棉裂。

晶体培育复刻天然成矿环境

Crystal CultivationSimulate Natural Gem-forming Environment

晶体培育 | 复刻天然成矿环境

Adopt upgraded PVT for moissanite plus CVD & HPHT dual techniques for lab diamond. Crystals grow slowly under constant temperature & high pressure; defective roughs are scrapped and only premium blanks proceed to processing.

采用改良PVT莫桑石生长工艺+CVD/HPHT双路线培育钻石，恒温高压慢周期养晶，严控炉体温差，瑕疵晶坯直接作废，优选优质原石进入加工。
