Italian architect Cristina Celestino has designed a coloured glass candle holder in Diptyque's signature oval shape for the brand's first refillable candle.

Created as part of the Les Mondes de Diptyque collection, the candle holder was designed "to achieve a monolithic volume while maintaining a soft, tactile quality".

It was created as the brand's first refillable candle and can be used multiple times with replacement oval blocks that fit exactly into the glass form.

According to the brand, it took three years to develop as it needed to ensure the wax would burn evenly in the oval shape and could easily be replaced.

Celestino's design stacks a trio of glass rings on top of each other, which is a reference to Diptyque's three founders and "subtly pays homage to their fruitful creative union".

The vessel was manufactured using a pressed glass technique, also referred to as moulded glass – a method used to create intricately designed glassware. The process involves placing molten glass into a mould and then using a plunger or a pneumatic device to press the glass into the desired shape.

"It [pressed glass] is the most suitable for creating a compact object with highly precise and significant details, all while maintaining quality standards," explained Celestino.

"I've always had a deep affinity for glass and consistently experimented with it in crafting small objects like flower vases and, in the case of my brand Attico Design, candle holders."

Celestino designed Diptyque's glass candle holder with the aim of being able to dramatically change the mood of a room.

"Glass carries an innate sense of preciousness and sophistication and can be shaped to give rise to sinuous and delicate forms, either through hand blowing or moulds."

"Glassware can significantly influence the mood and atmosphere of an interior space: variations in transparency, refraction, and reflection that glass offers add a unique dimension of depth and beauty to interiors."

The candle holder has a glass lid that fits neatly beneath the base, and the collection includes a snuffer and wick trimmer.

The coloured holders, which come in blue, red, green, grey and orange, can be refilled with one of five scented wax blocks that were created with five locations around the globe in mind – Nymphées Merveilles (Milan), La Forêt Rêve (Mexico), Temple des Mousses (Kyoto), La Vallée du Temps (China) and Terres Blondes (Colorado).

Other candle holder designs featured on Dezeen include Travis Barker's skull collection for Buster + Punch and Zaha Hadid's amorphous stainless steel candle holders.
