翡翠戒指尺寸完全指南：港圈對照表 + 量度方法
Jade Ring Size Complete Guide: HK Size Chart + How to Measure
翡翠戒指唔能夠改圈，選錯尺寸就無法修改。呢篇文章教你點樣正確量度手指，附有完整港圈 4–30 號對照表，幫你一次過揀到啱尺寸嘅翡翠戒指。
翡翠戒指嘅尺寸選擇係購買前最重要嘅一步。與金屬戒指不同，翡翠係天然石材，一般情況下無法改圈（即改變尺寸）。一旦選錯，就只能重新購買，因此選擇正確尺寸非常重要。
翡翠戒指嘅特殊性
- 翡翠係天然石材，硬度高但脆，無法像金屬戒指咁隨意改圈
- 戒面高度會影響佩戴舒適感——戒面越高，戒圈需要越鬆
- 寬版戒指（5mm以上）需要比一般戒指大半個圈口
- 不同手指嘅尺寸可能相差 2–4 個港圈號碼
量度最佳時機
手指嘅尺寸會因時間、溫度、飲食而有所變化。建議喺以下情況量度：傍晚時分（手指略為脹大，最接近日常佩戴狀態）；正常體溫下（天氣寒冷時手指會收縮，量度結果偏小）；飯後約一小時（避免剛飲大量水後量度）。
如何量度戒指尺寸
- 步驟一：剪一條細紙條，繯在指定手指嘅指根一圈，用筆標記重疊嘅位置
- 步驟二：將紙條平放在尺子旁，量度兩個標記之間嘅距離（即指圈內圍，單位：mm）
- 步驟三：根據量度到嘅內圍，對照以下表格，找到對應嘅港圈號碼

舒適度測試
試戴翡翠戒指時，進行以下測試：戴入時需要稍微用力，但唔應該太緊；戒指可以輕微轉動，但唔會自行滑落；握拳時唔應感到不適或夾緊；脫下時需要稍微用力，但唔應極度困難。
各手指嘅選擇建議
- 食指：通常係最粗嘅手指，量度時要特別注意指節位置
- 中指：最常見嘅戴戒指手指，尺寸較為標準
- 無名指：左右手可能有差異，建議兩隻手都量度
- 尾指：通常最細，注意唔好選太鬆，容易甩落
💡 購買貼士：建議傍晚量度，手指略為脹大時尺寸最準確。如果介乎兩個尺寸之間，建議選較大嘅尺寸。寬版戒指（5mm以上）建議比一般戒指大半個圈口。如有疑問，歡迎 WhatsApp 我哋，我哋可以協助你量度合適嘅尺寸。

Jade Ring Size Complete Guide: HK Size Chart + How to Measure
Choosing the right ring size is one of the most practical steps when buying jadeite jewellery. A ring that is too tight is uncomfortable; one that is too loose risks falling off. This guide walks you through how to measure your ring size at home and how to read the Hong Kong sizing chart.
Why Ring Sizing Matters for Jadeite
Unlike metal rings, jadeite rings cannot be resized without risk of cracking. Getting the size right before purchase is essential. Jadeite is also typically set in fixed silver or gold mounts, so the ring size is determined by the mount — not the stone itself.
How to Measure Your Ring Size at Home
- Step 1: Cut a thin strip of paper and wrap it snugly around the base of the finger you want to measure. Mark where the paper overlaps.
- Step 2: Lay the paper flat against a ruler and measure the distance between the two marks (this is your inner circumference, in mm).
- Step 3: Match your measurement to the size chart below to find your Hong Kong ring size.

Comfort Test
When trying on a jadeite ring, perform the following checks: it should require slight effort to put on, but should not feel painfully tight; the ring should be able to rotate slightly, but should not slide off on its own; making a fist should not cause discomfort or pinching; removing the ring should require slight effort, but should not be extremely difficult.
Tips by Finger
- Index finger: Usually the thickest finger — pay special attention to the knuckle when measuring
- Middle finger: The most common finger for rings; sizes tend to be standard
- Ring finger: Left and right hands may differ — measure both
- Pinky: Usually the smallest — avoid choosing too loose a size, as the ring may slip off
💡 Buying tip: Measure in the evening when fingers are slightly swollen for the most accurate reading. If you fall between two sizes, choose the larger one. Wide-band rings (5mm+) should be sized half a size larger than usual. If in doubt, WhatsApp us — we're happy to help you find the right fit.
