Crown of Light Diamonds Cruise Port Guide: What Makes the 90-Facet Cut Different

If you have spent any time browsing through jewelry stores at cruise ports, you have definitely seen the name Crown of Light Diamond or Diamonds International appear on nearly every cruise port. That is one of the largest jewelry stores in the world and usually number one recommended store by the cruise lines, and there is a reason for that. The Crown of Light Diamonds are not just marketing — it is a genuinely different diamond cut with a US patent behind it and a light performance that stops people mid-sentence when they see it in person.

I have spent nine years at sea helping cruise guests understand what they are looking at in port jewelry stores. The Crown of Light is the one diamond cut I tell people to at least put on their finger, even if they are not planning to buy. Here is everything you need to know about it before you step into a Diamonds International store.

The Crown of Light Diamonds Cruise Port Experience

A traditional round brilliant diamond has 58 facets — tiny flat surfaces cut at precise angles to bounce light back to your eye. The Crown of Light has 90 facets. That is 32 extra surfaces, each one catching and returning more light than a standard cut can manage.

More facets means more fire. You see more of those flashes of color — the reds, blues, and yellows that dance across the surface when the stone moves. It also means more brilliance — the pure white light return that makes a diamond look alive. When you put a Crown of Light next to a standard round brilliant, the difference is not subtle. The Crown of Light looks brighter, livelier, and more colorful. It catches the eye from across the room.

This is not a gimmick. Diamonds International holds the US patent on the Crown of Light cut. You cannot buy it anywhere else — not online, not at your local jeweler, not at any other port store. It is exclusive to DI, which means the only place you will see one in person is at a cruise port or a DI location in a destination city.

Why the Cut Matters More Than the Size

Here is something I have learned after watching thousands of guests try on diamonds: a smaller stone with a superior cut will out-sparkle a larger stone with a mediocre cut every single time. Cut quality determines how much light enters the diamond and how much of it comes back out. It is the single biggest factor in how beautiful a diamond looks on your hand.

The Crown of Light was engineered specifically to maximize light return. Those extra facets are not decorative — they are functional. Every angle was calculated to capture light that a standard 58-facet cut would lose. When you look at a Crown of Light, you are seeing the result of a deliberate optical design, not just a bigger stone.

This matters even more in a cruise port setting. You are comparing stones under jewelry store lighting, not in your own home. A diamond with superior light performance will look good under any light — bright showroom spots, dim restaurant candles, indirect daylight through a window. That is the real test, and it is where the Crown of Light earns its reputation.

The Diamond Bar Experience

One of the things I appreciate about Diamonds International is the Diamond Bar. This is a custom-build station inside the store where you can pick a loose Crown of Light stone, select a setting — white gold, yellow gold, rose gold, platinum — and have the jeweler assemble your piece while you are still in port.

This is not something you can do at a mall jewelry store. You are choosing the exact stone you want, seeing it loose under magnification, and watching your ring or pendant come together. Because the work is done on-site, turnaround is fast — typically the same afternoon. If you shop early in the day, there is plenty of time for sizing and assembly before you need to be back on the ship.

For anyone shopping for an engagement ring or a milestone anniversary piece, the Diamond Bar turns what could be a rushed port purchase into a genuinely personal experience. You are not buying a pre-set ring from a case. You are building something around the stone you chose yourself.

The Lifetime Upgrade Policy

Diamonds International offers a lifetime upgrade guarantee on Crown of Light purchases. This means you can trade in your original stone and apply its full purchase price toward a larger Crown of Light diamond down the road. If you buy a one-carat Crown of Light today and decide you want a larger stone five years from now, that one-carat value transfers directly — you only pay the difference.

This is the kind of policy that makes a cruise port diamond purchase feel less like a one-time gamble and more like the start of a long-term relationship with a piece of jewelry. Your diamond grows with you. The value you invested stays invested.

How Crown of Light Compares to Other Diamond Cuts

If you walk into a jewelry store and ask to see diamonds, you will encounter a range of cuts — round brilliant, princess, cushion, emerald, oval, pear. Each has its own character, and personal preference matters a lot here. But in terms of raw light performance, the Crown of Light sits in a category of its own because of that 90-facet architecture.

A standard round brilliant reflects about 85 percent of the light that enters it. The Crown of Light, with its additional facets and optimized angles, pushes that number higher. You see it, but more importantly, you feel it — there is a liveliness to these stones that makes even people who do not know much about diamonds stop and stare.

That said, the Crown of Light is not the only quality diamond in a DI store. Diamonds International carries DeBeers Forevermark diamonds, which are individually inscribed and selected for exceptional quality. They carry natural fancy-colored diamonds in yellows, brown, and blues. The Crown of Light is simply their signature — the one cut that defines the DI brand.

What to Know Before You Shop

If you are planning to look at Crown of Light diamonds on your next cruise, here are a few things that will make the experience better:

Shop early in the day. If you are having a piece custom-built at the Diamond Bar or need a ring sized, jewelers need time. Morning shoppers get the best service and the most relaxed experience. Afternoon gets busy, and you do not want to be the guest sprinting back to the ship with a ring that still needs adjusting.

Ask to see the stone loose. Before it goes into a setting, look at the diamond by itself. Move it under the light. Tilt it. Watch how the fire shifts. A loose stone tells you everything a set stone hides — clarity, color, and cut quality are all easier to evaluate before the diamond is mounted.

Compare side by side. A Crown of Light next to a standard round brilliant makes the difference obvious. If the store has both in stock, ask to see them together. You will understand the 90-facet advantage immediately, and it will help you decide if the Crown of Light is worth it for you.

Think about the setting. The Diamond Bar lets you customize, but that means you should have an idea of what you want. White gold is the most popular and the most neutral — it puts all the attention on the diamond. Yellow gold and rose gold add warmth. Platinum is the premium option, heavier and more durable. Think about what the person wearing it prefers before you walk in.

Bring your VIP card. The Crown of Light is a premium collection, and VIP card holders get preferred pricing and additional perks at Diamonds International locations. If you do not have your cards yet, grab them before you sail.

Which Ports Carry Crown of Light

Crown of Light is available at every Diamonds International location in the Caribbean, Mexican Riviera, and Alaska. If your cruise stops at Cozumel, St. Thomas, Grand Cayman, Nassau, Aruba, Curacao, Grand Turk, Amber Cove, Roatan, San Juan, Belize, or Bonaire, there is a DI store with Crown of Light inventory waiting for you.

Each DI location carries the full Crown of Light collection, but certain stores have unique advantages. The DI in St. Thomas has a flagship-level Hublot boutique under the same roof, which makes it an easy stop for both diamonds and watches. The DI in Cozumel is one of the busiest in the Caribbean, with a deep inventory and a fast Diamond Bar turnaround. Every DI store offers the same lifetime upgrade guarantee — the policy follows you from port to port.

The bottom line: wherever your cruise takes you, Crown of Light is there. The cut is the same, the patent is the same, and the experience of seeing those 90 facets catch the light for the first time is the same. Just make sure you give yourself enough time to really look.

Plan Your Shopping Before You Sail

I have spent nine years helping cruise guests navigate port shopping — over 3,000 days at sea and more than 80 countries. The one thing I have learned is that a little preparation goes a long way. Knowing where to go and what to look for before you step off the ship makes all the difference. That is why I created the VIP cards — a simple way to get preferred pricing and extra perks at the stores I trust most. Grab yours at portshopping.expert before you sail.
