知道自己的指圍尺寸，能夠讓您佩戴更加舒服合適。所有台灣‧寶石的戒指都採美國標準尺寸。
• It’s best to measure your finger at the end of the day.
• It’s best to measure when your fingers are warm, not cold.
• If your knuckle is a lot larger than the base of your finger, measure the base of your finger and your knuckle and select a size in between.
•Your ring size will be about half a size larger on your dominant hand (the hand you write with).
*測量指圍最好的時間是一天要結束的時候。
*測量時手指的溫度最好是溫熱的，而非冰冷的。
*如果您的指關節比指圍大，請同時測量指關節以及指圍，然後挑選介於兩者之間的尺寸。
*指圍在慣用的那手(寫字的手)會大大約半號。
Use a non-stretchy piece of string, or cut a strip of paper about 100mm long and 10mm wide. Wrap it around the base of your finger. Using a pen, mark the place where the string or paper overlap, making a complete circle. Compare the length of the marked string or paper with the measurements below to determine your ring size. If you are between sizes, select the larger size.

請準備一條沒有彈性的繩子或是剪一條長10公分寬1公分的紙條，將繩子或紙條順著您的手指根部繞一圈，拿支筆在繩子或紙片重疊處做記號。將您量出的長度與下列的標準長度相比較來決定您的指圍，如果您的長度是介於兩個尺寸之間，建議您選擇較大的那一個尺寸。
