The Eos Open Ring is an open-style two-stone diamond ring handcrafted in our Byron Bay Hinterland atelier. One 4.00 x 2.00mm marquise-cut diamond paired with one 4.00 x 2.00mm baguette-cut diamond, set on an open band that leaves an intentional gap for a contemporary asymmetric silhouette.

Made to order by Australian goldsmiths in 9ct or 18ct yellow, white, or rose gold, as well as platinum. Choose your diamond origin (natural or lab-grown F VS) and ring size (5-10) to begin your bespoke piece. Looking for related geometric pieces?

Frequently asked questions

What is an open ring?
An open ring features an intentional gap in the band, creating an asymmetric, contemporary silhouette. The Eos pairs two small diamonds, a marquise and a baguette, across the open gap.

Is the Eos an engagement ring?
The Eos is positioned as a contemporary fashion or stacking ring rather than a traditional centre-stone engagement ring. Its delicate diamond accents (0.10ct total) work well as a complement to an engagement ring or as a daily-wear statement piece.

Natural or lab-grown diamonds?
Both options are offered. You can choose between natural and lab-grown F VS diamonds at checkout.

How long does it take to make?
Each Eos Open Ring is hand-made to order in our Byron Bay Hinterland atelier by Australian goldsmiths. Lead times typically run 4 to 6 weeks. Free shipping Australia-wide once dispatched, with Lucano's lifetime craftsmanship warranty.

Total Diamond Weight: 0.16 ct

Are lab grown diamonds as good as natural diamonds?
Lab grown and natural diamonds are chemically, physically, and optically identical. Every Lucano diamond is F VS graded. The only differences are provenance and price: lab grown diamonds cost less for the same colour and clarity grade, while natural diamonds carry geological rarity.
What does F VS mean in your diamond grading?
F is the colour grade, the highest 'colourless' tier just below D and E. VS means 'Very Slightly Included', where inclusions are visible only under 10x magnification and not to the naked eye. Every Lucano diamond meets or exceeds this standard.
Where is Lucano jewellery made and how are your diamonds sourced?
Every piece is hand-made in our Byron Bay Hinterland studio by Australian goldsmiths. Our founder is a member of St Eligio, Università e Nobil Collegio degli Orefici jewellery association established in Rome in 1508. Gold is sourced from ABC Refinery (Australia's only LBMA/SGE/COMEX-accredited independent refiner), and every diamond is traceable, RJC-certified, and comes with full chain-of-custody documentation.
What's the difference between 9ct, 18ct, and platinum settings?
9ct gold is harder and more affordable. 18ct gold has a richer warmth and higher gold content (75%). Platinum is the densest and most durable; it doesn't tarnish and develops a soft patina over time. Every Lucano setting holds your diamond with the same goldsmithing precision.
How long does a Lucano hand-made piece take?
Each piece is hand-made to order in approximately 6 to 8 weeks. You can see your specific production and delivery timeline on the product page.
