Frequently asked questions

What is a solitaire engagement ring?
A solitaire engagement ring features a single diamond as the centre stone, set alone on a clean band. It is the most classic and enduring engagement ring style, allowing the centre stone to be the sole focal point without surrounding diamonds.

Why round brilliant?
The round brilliant cut has 57 or 58 facets engineered to maximise light return. It produces more fire and sparkle than any other diamond shape and remains the most popular engagement ring cut globally.

What is the difference between Helios and Helios Lumière?
Both centre on an 8.00mm round brilliant solitaire. The standard Helios uses our classic band profile; the Helios Lumière uses a slimmer, more delicate band. The centre stone, certification, and craftsmanship are identical.

Are the diamonds certified?
Yes. Lab-grown diamonds are IGI-certified. Natural diamonds of 0.30ct or above are GIA-certified. All diamonds are graded to F colour and VS clarity.

How long does it take to make?
Each Helios Round Solitaire 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 (available options):

  • 0.50 ct
  • 1.00 ct
  • 1.50 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.
