Carina Ethical Diamond Trilogy Engagement Ring

Product Details

The Carina star formation is likened to the keel of a ship used by Jason and the Argonauts in Greek mythology. Knowing this ship was protected by Hera, the goddess of Marriage, we fell in love with the mystical connotations this name brings to the design.

The ring itself is inspired by Meghan Markle's cushion cut, Botswana-sourced triple diamond engagement ring, representing three love stories bound into one. As well as the central stone chose by Prince Harry, Megan’s custom-made design also features two smaller diamonds previously owned by Princess Diana. This is why we have incorporated two sparkly stones either side – sure to make any bride-to-be feel like a princess.

Celebrate your love and the beginning of your journey with this sparkling trilogy ring, and enjoy it even more knowing that it is made with the most sustainable materials. Made from 100% recycled platinum, this ring is crowned with three brilliant-cut, responsibly sourced diamonds. This beautiful ring will arrive accompanied by a certificate of authentication to assure you and your fiancé that the most ethical materials available have been used to create this lifelong ring.

Her new ring will arrive in a 100% recyclable Arabel Lebrusan box, cushioned in velvet lining.

This ring is also available in 18ct Yellow Gold. Just drop us a line for a quote.

How long will my order take to arrive?
If you have purchased a silver item, we aim to post your order within three to five working days. For our Wedding Bands and Engagement Rings most clients receive their finished jewellery within four to six weeks, but let us know if you need yours sooner and we'll let you know whether we can meet your deadline. We endeavour to provide an exceptional and friendly service to all our clients.
Do you have a showroom where I can try your wedding and engagement rings?
You can certainly try our jewellery but unfortunately we do not have a show room - Our studio is based in Brighton. We can meet you in this area during the weekends, taking away the hustle and bustle of busy London life and to help you choose your perfect rings in such an lovely location.
If you are unable to visit us here in Brighton, we would be more than happy to meet with you in London during the week, in a convenient location for you. Two of our favourite places to meet clients are Searcy’s Champagne bar in St Pancras Station or The Fence in Farrington, both with easy connections to trains and tubes. These perfect venues will help you to feel comfortable and at ease when selecting your forever rings.
How will I know if my chosen item is ethically sourced?
Arabel Lebrusan uses recycled, Fairtrade metals and ethically sourced stones for the majority of our jewellery. Most items from the Bridal Collections are ethically sourced and you will find detailed descriptions of the creation process and materials used on the individual website pages for each item in our collections. We are always on the look for new ethical materials available to the market.
I cannot find my size in your website, What if my finger size is bigger or smaller, can you also make it? 
Yes, we also make larger and smaller sizes - just drop us an email for a quote. Requests for smaller sized rings will be quoted at the same price as the smallest ring size available on the website. Larger sizes tend to be a bit more expensive.
How does the Arabel Lebrusan Bespoke Service work?
Very simple, take a moment to visit our Bespoke Service Examples page ( and if you like the style, drop us an email outlining what it is that you’re after. It is always helpful if you indicate your budget and timeframe. Some periods in the year we are extremely busy, so please give us enough time; 8-12 weeks should be sufficient. You can view a detailed explanation of the bespoke service here. (
How much does your Bespoke Service cost?
That depends on the design, but we usually start our bespoke service at around £950. We only create bespoke items in 18ct gold or Platinum (unless it is a large bespoke silver cuff you are after, we love making those!)
