[diamond] => Array
        (

            [girdle_min] => 
            [girdle_max] => 
            [girdle_condition] => 
            [culet_size] => None
            [culet_condition] => 
            [fluor_color] => 
            [fluor_intensity] => Faint
            [has_cert_file] => true
            [country] => Hong Kong
            [city] => Hong Kong
            [lab] => GIA
            [total_purchase_price] => 433.62

            [total_sales_price_in_currency] => 1080.5523
            [cert_num] => 7276144251
            [stock_num] => RG611
            [has_sarineloupe] => false
            [sarineloupe_url] => 
            [is_fancyColor] => false
        )

我想将此作为产品添加到我已完全添加产品成功但我无法添加属性（Clarity，Cut，Symmetry，Polish）。 我想在产品上应用这些属性。添加这些属性后应显示在woocommerce产品的属性部分
