The crystal bottle and the crystal bottle adorned with gold leaf are produced by the Lalique crystal manufacture according to the same process. Four master glassmakers must work together to fashion the bottle, using the handcrafted hot mould technique. Taken up at 1150°C, the crystal is formed in a wooden shaping block before being placed into a cast-iron mould heated to 400°C and annealed for seven hours.
To conceive the stopper, the "pressed" technique requires no less than five glassmakers. The cutting and polishing is performed once the bottle is cold. Its motifs are polished and sandblasted, then each bottle is signed and numbered before it is sealed with baudruchage and a delicate gold thread.
The transparent crystal "Swallows" motif is set against a sandblasted crystal background. The ribs separating each "window" are also transparent. A stylized iris bouquet showcases the fragrance's starring ingredient on the stopper.
The crystal bottle is housed in a luxurious white diamond-shaped coffret, inspired by René Lalique's jewel boxes. Circled with a gold metal band engraved with the name of the fragrance, the coffret is crowned with a plaque bearing the emblem of Lalique.
