The installation, which is a multi-punch hydraulic press, compresses a special container – a growth cell, inside which is a catalyst and graphite. The process of growing a large crystal or several small ones lasts about a week.[/ultimate_heading][/vc_column][vc_column width=”1/6″][/vc_column][/vc_row][vc_row][vc_column width=”1/6″][/vc_column][vc_column width=”2/3″][vc_row_inner content_placement=”middle”][vc_column_inner width=”1/2″][ultimate_heading sub_heading_color=”#a0a8c3″ main_heading_font_family=”font_family:|font_call:” sub_heading_font_family=”font_family:Montserrat|font_call:Montserrat” sub_heading_font_size=”desktop:20px;” sub_heading_line_height=”desktop:25px;” sub_heading_margin=”margin-top:20px;margin-bottom:20px;”]Diamonds grown in the laboratory have the same physical, chemical, and optical characteristics as natural diamonds.[/ultimate_heading][kleo_gap][ultimate_heading sub_heading_color=”#252646″ main_heading_font_family=”font_family:|font_call:” sub_heading_font_family=”font_family:Montserrat|font_call:Montserrat” sub_heading_font_size=”desktop:13px;” sub_heading_line_height=”desktop:21px;” sub_heading_margin=”margin-top:20px;margin-bottom:20px;”]The properties of the obtained diamond single crystals are absolutely no different from natural diamonds.
