The Penthouse by Ali Diamond

High Jewelry. One-of-One. No Compromises.

The Penthouse is Ali Diamond’s most elite bespoke offering — a private, by-appointment-only service for clients who demand more than luxury. This is haute joaillerie at its highest level.

Every piece created under The Penthouse label is a one-of-one, never repeated, never replicated. It’s not just custom — it’s singular.

What Defines The Penthouse:

• Investment-Grade Only:
  We work exclusively with the finest materials on Earth — D-F color, VVS clarity diamonds, vivid untreated colored gemstones, and gold and platinum of the highest purity. Every stone is chosen for its rarity, value, and long-term worth.

• One-of-One Masterpieces:
  Each design is created from scratch, tailored entirely to you. Once crafted, that design is archived and never reproduced — your piece remains unique forever.

• High Jewelry Standards:
  From stone setting to finishing, every step follows the traditions of high jewelry ateliers — meticulous, precise, and meant to last generations.

• Ultra-Private Service:
  Design sessions are held in-person or virtually, directly with Ali or our master designers. Everything is discreet, direct, and curated for your lifestyle and vision.

The Penthouse isn’t a collection. It’s a level.
A level reserved for those who view jewelry not just as adornment, but as identity, investment, and art.
