Prometheus Ships Diademas for OpusX & God of Fire
Prometheus Ships New Diademas for OpusX and God of Fire
Prometheus has started shipping new Diadema vitolas for four of the most sought-after Arturo Fuente-made lines. Here's the honest angle: this isn't a story about new sizes. The Prometheus Diademas release takes celebrated, scarce blends and gives them a dramatic figurado shape, in tiny numbers. For serious Fuente and OpusX smokers, that mix is what makes it one of the more interesting Fuente-related arrivals of 2026.
At a glance
The key facts first:
- Four lines get the Diadema treatment: OpusX Rare Black, Carlito's X Rare Purple, God of Fire KKP Never Back Down, and KKP Special Reserve.
- Three sizes each: Diadema 54 (7 1/2 x 54), Diadema 56 (6 1/4 x 56), Diadema 60 (5 1/2 x 60).
- Made by Tabacalera A. Fuente in the Dominican Republic, sold by Prometheus.
- Staged rollout: 8 of 12 SKUs shipped first; the other four land later in September 2026.
- Just 100 boxes of each, at 10 cigars per box — and these are not limited editions.
What's Actually Shipping
Let's keep the facts straight, because there are a lot of moving parts. The four collections getting new Diademas are the Fuente Fuente OpusX Serie "Heaven and Earth" Rare Black, Carlito's X Rare Purple, God of Fire KKP Never Back Down, and God of Fire KKP Special Reserve. All of them are made by Tabacalera A. Fuente y Cia. in the Dominican Republic and sold by Prometheus. Each line gets three Diadema sizes, which adds up to 12 SKUs in total.
The Prometheus Diademas rollout is happening in stages. The first shipment includes eight of those SKUs. The remaining four are expected later in September 2026. So even the release schedule asks a little patience from collectors.
The three new Diadema sizes
| Diadema 54 | 7 1/2 x 54 |

| Diadema 60 | 5 1/2 x 60 |
| Each line | Gets all three sizes (12 SKUs across the four collections) |
How Small Are the Numbers?
Very small. In this first shipment, Prometheus is sending just 100 boxes of each cigar, and every box holds only 10 cigars. That is a tiny run for blends this coveted, which is why the Prometheus Diademas are drawing so much attention. Here's the important distinction, though: these are not limited editions. The reporting is clear on that point. They are classified as regular production, even if the production and the availability are extremely limited right now. So don't call them limited editions — but do expect them to move fast.
Why the Diadema Shape Matters
The Diadema is not just a pretty shape. It's an elaborate figurado with a tapered head, and it takes real skill to roll well. That taper can also change how the cigar smokes and develops from light to finish. With blends of this caliber, that's the fun part. Smokers who already know the traditional vitolas now get to experience the same tobaccos through a completely different format. If you enjoy Arturo Fuente cigars, a familiar blend in a new shape is a genuinely different ride.
The Rare Purple Name Change
Here's a detail worth getting right. There is a naming change on the Rare Purple side. The existing 6 7/8 x 44 torpedo keeps the Purple Rain name. The new Diademas, however, are branded Carlito's X Rare Purple. The blend itself does not change. It's still the same Dominican recipe, including wrapper tobacco grown at Chateau de la Fuente. Only the name and the shape are new.
A Quick Background on the Blends
- OpusX Rare Black debuted in 2019. It uses a Dominican wrapper grown at Chateau de la Fuente. Its binder and filler stay undisclosed.
- Carlito's X Rare Purple shares that Dominican character, with wrapper tobacco from Chateau de la Fuente.
- God of Fire KKP Special Reserve arrived in 2022 for God of Fire's 15th anniversary. It's a Dominican puro.
- God of Fire KKP Never Back Down followed in 2024 for the 20th anniversary. It's also a Dominican puro.
Don't Overlook the Rare Black Six-Cigar Selection
Prometheus is also shipping a Fuente Fuente OpusX Rare Black Six Cigar Selection. It carries a $425 MSRP and includes the five Rare Black vitolas plus an extra Diadema 54, for six cigars in all. Like the rest of the Prometheus Diademas rollout, it starts small: only 100 samplers are part of this initial shipment.

The Mardo Take
This is the kind of release that reminds us why Arturo Fuente keeps generating so much excitement. They aren't reinventing these celebrated blends. They're presenting them in a format worthy of their reputation. Yes, the collector appeal is real, because these are scarce. But the bigger draw is getting to smoke coveted Fuente tobaccos in vitolas most collectors have never tried. Browse our OpusX cigars and God of Fire cigars to see where these blends live at Mardo.
The Bottom Line
Coveted blends. Three new Diadema shapes. Tiny initial allocations. That's the real story behind the Prometheus Diademas, not a simple size update. For serious Arturo Fuente and OpusX fans, this is one of the 2026 releases worth watching, and availability is likely to be extremely tight. If a shape like this is on your list, it pays to move sooner rather than later.
Coveted blends, brand-new shapes.
