Addendum Crystal Highball or Tumbler Glasses – Set of 6
Two contrasting proportions share one refined decorative identity. The low tumbler has a broad, grounded profile, while the highball introduces a taller and more slender silhouette for long drinks.
Smooth clear walls place the emphasis on the narrow groove pattern around the lower body. This restrained treatment gives the glasses a distinctive appearance without covering the complete surface with ornament.
 
The Addendum glasses bring sophistication to cocktail service, formal table settings and relaxed gatherings. Their balanced forms combine traditional crystal craftsmanship with a more contemporary visual character.

The engraved band creates a defined transition between the transparent upper body and the substantial crystal base, giving both proportions a clear visual and tactile focus.
 
THE ARTISTRY OF MATERIALS
Pure crystal containing 24% PbO gives the narrow grooves enough definition to remain clearly visible against the smooth surrounding walls. On the low tumbler, the pattern spreads around a broad circumference; on the highball, it forms a tighter band between the elongated body and solid base.
As light enters the cuts, it gathers briefly within the repeated channels before passing into the open crystal above. This produces a concentrated ring of reflections without interrupting the transparency of the drink.
 
EXCLUSIVITY & HERITAGE
Addendum interprets late classical motifs through a repeated groove rather than literal historical ornament, reducing the reference to a disciplined pattern cut directly into the crystal.
Each piece is crafted in Italy by Mario Cioni and presented as part of the G.P.Grant Crystal Selection. It may bear the original Mario Cioni maker’s mark.
Applying the same motif to two distinct proportions allows the collection to move between spirit service and long drinks while preserving one recognisable design language.
