Diamonds have long symbolized love, legacy, and light. But not all diamonds are created equal. While the traditional round or princess cuts continue to captivate, there exists a more elusive world—rare diamond shapes that break free from convention.
At San Liora, we believe jewelry should speak to the soul. It should reflect not just beauty, but individuality. And for those seeking something profoundly personal, rare diamond shapes are a radiant way to stand apart.
🌟 What Makes a Diamond Shape Rare?
Diamond rarity isn’t always about how many exist—it’s about how difficult they are to cut, how much skill they require, and how uncommon they are in commercial jewelry.
A shape is considered rare when:
-
It requires high precision and symmetry.
- It involves significant wastage of the rough stone
-
It’s not easily found in mainstream collections.
- It often carries symbolism or design rooted in history or art.
Rare shapes are usually reserved for custom creations, bespoke rings, and collectors’ pieces.
The 5 Most Unique and Rare Diamond Shapes
1. Kite Cut – The Shape of Ascent
🪁The Kite cut is known for its strong geometry and celestial silhouette, often used in modern, asymmetric designs.
- Story: Inspired by freedom and flight, it reflects growth, independence, and imagination.
- Why it’s rare: Limited use in mainstream jewelry, mostly custom-cut.
- Ideal for: Those who want to defy norms and embrace artistic expression.
💍At San Liora, we adore the kite cut for its architectural elegance—it looks especially stunning in minimalist bezel or east-west settings.
2. Lozenge Cut – Vintage, Reimagined
The Lozenge, or diamond-shaped diamond, is a throwback to antique European jewelry. Its subtle symmetry makes it a poetic alternative to more common geometric cuts.
- Story: Associated with protection and the eye of truth in ancient cultures.
- Why it’s rare: Difficult to align with modern settings and hard to source.
- Ideal for: Vintage lovers and spiritual souls.
💍Pair it with rose gold or milgrain detailing to give it that old-world romance with a fresh twist.
3. Shield Cut – Strength in Style

Shield cuts represent strength and grounding. Their bold, angular shape makes a striking centerpiece in custom engagement rings.
- Story: Symbolizes courage and protection—often chosen for meaningful heirloom pieces.
- Why it’s rare: Often cut by hand for artistic projects; rarely produced in bulk.
- Ideal for: Those seeking a talismanic, statement-making design.
Imagine this with side tapered baguettes—classic with an edge.
4. Crescent Cut – Whisper of the Moon

This moon-shaped beauty captures emotion and movement. The crescent cut is one of the most whimsical and dreamlike shapes available.
- Story: Symbolizes femininity, mystery, and cycles of renewal.
- Why it’s rare: Tricky to cut and even trickier to set symmetrically.
- Ideal for: Moon lovers, artists, and spiritual souls.
We love crescent accents in celestial-inspired pieces—pair them with stars or salt-and-pepper diamonds for a truly cosmic vibe.
5. Coffin Cut – Darkness, Redefined

A gothic masterpiece, the coffin cut is ultra-niche and unapologetically bold. It's often cut from darker diamonds, like salt-and-pepper or black diamonds.
- Story: A reminder of mortality, but also of legacy, depth, and intensity.
- Why it’s rare: Often custom-designed, this shape is a favorite among modern rebels and edgy romantics.
- Ideal for: Alternative bridal jewelry, gothic aesthetics, or statement pendants.
San Liora’s designers can create custom pieces with coffin cuts that defy all conventions—yet still radiate luxury.
