Forty-seven matched stones. One unbroken circle of light. Alcyone is the bracelet you put on for a milestone, then stop wanting to take off. There is no single centre. Every round brilliant lab-grown diamond carries the design forward around the wrist.
Each of the 47 lab-grown diamonds measures 3.00mm, giving a total weight of approximately 5.17ct. Four claws hold every stone within a square box frame. The linked frames form a smooth, flexible line that follows the wrist. A box clasp with a figure-eight safety catch closes the bracelet, and it sits flat.
Why choose Alcyone
Alcyone gives equal weight to every part of the wrist. Its 47 evenly matched, 3.00mm round brilliant lab-grown diamonds form one continuous row and total approximately 5.17ct. The standard length is approximately 6.4 inches. Choose 14kt white, yellow or rose gold for the harder, more scratch-resistant gold, or 18kt in the same colours for more pure gold and a heavier feel. A figure-eight safety catch backs up the box clasp.
