The simplicity of the Thorn motif, with its distinctly natural edge, aesthetically aligns with Stephen Webster’s fascination with all things dangerously beautiful, the Thorn also holds a bittersweet undertone. Much like in love and life; there is no pleasure without pain, the Thorn is a darkly romantic symbol of resilience and protection.
Featuring a large green tourmaline central stone set in 18ct white gold, the Thorn Cocktail Ring is finished with fine white diamond pavé.
Style Code: WR1127

How To Measure

To measure your finger, you can use a tape measure. Measure the circumference of your finger in mm and find your corresponding size from the conversion chart above.

Choose a ring that already fits your finger well and measure the interior diameter of the ring in mm with a tape measure. Find your corresponding size from the conversion chart above.
If you order a ring and it's not quite the right size, let us know within 30 days of receiving your order and our in-house workshop can provide complimentary ring resizing.
*Excluding some collections* Top Tips
To get the most accurate measurement of your finger, measure at room temperature, when your hands are not unusually hot or cold.
Remember that your two hands differ slightly in size; a ring worn on a finger of the left hand may not be perfect for the finger on the right hand.
If you are hesitating between two sizes, choose the larger size.
