The Knot Duo is a duet of the traditional wedding band being paired with the engagement ring. The pair together is a symbol of the vow and bond made between two people when they tie the knot and make the pledge “… for better, for worse, for richer, for poorer, in sickness and in health, until death do us part.”

以麗澤美鑽®鑲嵌的愛結成雙是一對傳統的訂婚、結婚指環，這對指環是兩人的結婚信物，記載新人對婚姻的承諾：「……無論順境或逆境，富足或貧窮，健康或疾病，我都將愛護你、珍惜你、直到天長地久。」願那些佩戴此愛結成雙指環的佳人時刻愛護對方，把對伴侶的承諾記在心裡，直到永遠。
