The quick verdict
The bottom line: the Trinity ceramic is the sharpest-looking version of Cartier’s 1924 icon. It swaps the classic three-gold palette for 18K white gold and black ceramic, medium model, ref. B4234100, with each band 3.2 mm wide. The price is 2,080 USD or 2,800 CAD, which actually makes it the least expensive way into a medium Trinity ring. I bought mine at the Cartier boutique at Wynn Las Vegas and wear it on my little finger. Two things to know before you buy: the ceramic band cannot be resized, so your size has to be right on the day, and my sales associate indicated this version may be discontinued, so if it is the one you want, do not wait around.

Watch: the full unboxing
The full unboxing is in the video above, from the shopping bag and paperwork through to the ring on my finger. Everything below is the written breakdown with the specs, the sizing warning and my first impressions.
What the Trinity is
The Trinity is one of the most famous ring designs in the world. Louis Cartier created it in 1924, at the request of the French artist Jean Cocteau, as three interlocking bands that roll and move against each other rather than sitting fixed. In the classic version the bands are three colours of gold, and each carries a meaning: rose gold for love, yellow gold for fidelity and white gold for friendship. A century later the design has barely changed, because it did not need to.
The ceramic version keeps the rolling three-band construction and changes the palette. Two of the three bands read in bright 18K white gold and the third in deep black ceramic, so instead of the warm tricolour mix you get a hard black and white contrast. It is recognisably the same ring, but it wears completely differently: cooler, sharper and, to my eye, far more masculine than the tricolour, which is exactly why I chose it.
Unboxing and first impressions
I bought the ring in person at the Cartier boutique inside Wynn Las Vegas, and part of the point of the video is showing everything a genuine boutique purchase actually comes with, because the market is flooded with fakes. The paperwork matters. The receipt comes in the red Cartier folder and lists the item, the reference number, the ring’s individual serial number, the price and the payment method. Keep it. That documentation is a big part of your proof of authenticity later, especially if you ever sell.
The boutique also included two complimentary fragrance samples, Declaration and Pasha, a nice touch that costs them little and somehow still feels like an event. The certificate of authenticity comes sealed with a branded wax seal, which I opened on camera. Inside it carries the serial number matching the receipt, the purchase date, the boutique’s details and the certifier’s signature. One warning from the video worth repeating: Cartier boutiques generally will not authenticate a piece you bought from a third party, so that certificate and receipt set is what protects you.
The ring itself is wrapped inside a wax-sealed outer box, and Cartier includes a soft, unbranded travel pouch alongside the presentation packaging. The pouch is genuinely useful: it is the safest way to carry the ring when you travel, and it keeps the bands from scratching against anything else. Finally, the iconic red box, which opens with a push button, and the ring is sitting there in white gold and black ceramic. First impression out of the box: the contrast is even stronger in person than in photos, and the rolling movement of the bands is something you notice immediately. It feels engineered, not just decorative.
Specs and details
Reference: B4234100. Model: Trinity ring, ceramic, classic model (medium). Materials: 18K white gold (750/1000) and black ceramic. Band width: 3.2 mm per band (Cartier quotes this for size 52; dimensions vary slightly by size). Sizes: Cartier lists the ring from 46 to 72, with some sizes on a notify-when-available basis. Price: 2,080 USD, 2,800 CAD at Cartier at the time of writing.
Price and value
Here is the part that surprises people: the ceramic Trinity undercuts the classic tricolour medium model, which is 2,350 USD or 3,250 CAD. You are getting the same 1924 design, the same medium proportions and a full white gold construction for less than the three-gold version, because one band is ceramic rather than gold. If you prefer the black and white look anyway, this is not a compromise purchase, it is the better buy.
The value question hangs on the discontinuation talk. In the video I pass on what my sales associate told me at Wynn: the ceramic Trinity may be discontinued. Cartier has made no public announcement I can point to, so treat it as a rumour with a credible source rather than a confirmed fact. But if it does go away, buying at retail now, with full paperwork, is the cheapest this ring will ever be.
Sizing and wearing
This is the section to read twice. I wear mine on my little finger, and the Trinity has a trick to putting it on: the three bands roll over each other as the ring goes on, and in the video I show how to roll it into place so the bands sit properly stacked. Get that right and it sits flat and comfortable.
The critical sizing fact is that the ceramic band cannot be resized. A jeweller can work with gold, and I was told the white gold bands can be taken down by up to half a size, but ceramic does not stretch, shrink or solder. If you are between sizes, that is a real problem, and it is the strongest argument for buying this ring in a boutique where you can try the actual sizes on your actual finger, which is what I did in Las Vegas.
Scratches, maintenance and everyday wear
My honest position, and I say it in the video: luxury jewellery is for wearing, and scratches are part of the deal. The white gold bands will pick up marks with daily wear, and white gold can be refinished by Cartier if you ever want it brought back. The ceramic band cannot be refinished the same way, so a hard knock that chips or marks the ceramic is permanent in a way a gold scratch is not. That is the trade you make for the look. My advice is the same as it is for my Love ring: wear it, enjoy it, and do not keep a 2,800 dollar ring in a box because you are afraid of living in it.
Next to my classic Cartier Love ring, which is my wedding ring, the Trinity ceramic makes an interesting contrast: the Love is warm, fixed and traditional, the Trinity is cool, moving and a little bit mechanical. They share a design language without matching, which is why the pair works.
Who it is for
Buy the Trinity ceramic if you love the Trinity story but find the tricolour version too soft or too traditional, if you want a luxury ring that reads modern and works as a little-finger ring as easily as a wedding band alternative, and if you can buy in person and nail your size. Skip it if you are between sizes and buying blind online, or if you need a ring you can resize later as your hands change.
And if you are shopping used: the full set is everything. Receipt, sealed certificate with matching serial numbers, packaging, the works. In the video I walk through how to spot the authenticity tells, because there are convincing fakes everywhere, including all over Facebook. If a used Trinity ceramic comes with no paperwork and a price that seems too good, it is not a deal, it is a story you are choosing to believe.
