Frequently asked questions

What is a radiant cut engagement ring?
A radiant cut engagement ring features a rectangular centre diamond with brilliant-cut faceting, combining the elongated shape of an emerald-cut with the sparkle of a round brilliant. The radiant cut was invented in 1977 by Henry Grossbard and remains one of the most sparkle-intensive fancy shapes.

How does radiant-cut compare to emerald-cut?
Both are rectangular, but radiant-cut has brilliant-cut faceting for sparkle, while emerald-cut has long step-cut facets for clarity. Radiant-cut hides inclusions better and produces more fire. See the Imperia Emerald Solitaire for the emerald-cut version of this design.

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.

Can I choose between lab-grown and natural diamonds?
Yes. The Imperia Radiant Solitaire is offered with either IGI-certified lab-grown or GIA-certified natural F VS diamonds, at 0.50, 1.00, or 1.50ct centre weights.

How long does it take to make?
Each Imperia Radiant Solitaire is hand-made to order in our Byron Bay Hinterland atelier by Australian goldsmiths. Lead times typically run 4 to 8 weeks. Free shipping Australia-wide once dispatched, with Lucano's lifetime craftsmanship warranty.

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 4 to 8 weeks. You can see your specific production and delivery timeline on the product page.
