The story
About this creation
This yellow gold engagement ring, set with a breathtaking 5-carat lab-grown radiant-cut diamond, is a jewel impossible to ignore. Its design unites majesty with delicacy – the central diamond, with its striking “crushed ice” effect, blazes like a captured ray of sunlight. The shank is adorned with a refined row of delicate diamonds, guiding the eye toward the principal stone and accentuating its regal character.
When you slip on this ring, you gain far more than a jewel – you gain a symbol of your own strength, elegance and singular identity. It is a ring that reminds you that you are a woman unafraid to shine, to be seen, and to live fully. Its warm yellow gold delights both the eye and the skin, as though it carries a sliver of sunlight within it, while the diamond’s brilliance lends quiet confidence to every gesture.
Rings featuring a striking solitaire accompanied by a refined diamond pavé line trace their origins to the first half of the twentieth century. In Hollywood’s golden age, they were worn by actresses who immortalised the “big diamond – clean line” aesthetic, a symbol of independence, beauty and the strength of the feminine spirit.
The radiant cut, introduced in the 1970s, was conceived expressly for maximum light return — by tradition it is known as the “cut of joy”, for its interplay of light evokes the effervescence of champagne.
Lab-grown diamonds hold strong investment potential, owing to their consistent quality, ethical provenance and growing demand, which also sustains the secondary market. Larger stones in particular, such as the 5ct radiant, are highly sought-after “statement stones” whose value holds exceptionally well.
Within the same design, the centrepiece gemstone may be replaced with another stone of the client’s choosing.

Living with your jewel
Caring for your jewellery
Caring for jewellery matters more than most people expect. Your creation sparkles newly after a gentle cleansing: most gemstones, and diamonds especially, respond beautifully to a wash in mild soapy water. But not every gem. An emerald, for example, must never be washed this way; its natural character asks for a different, gentler care. Please always ask us how to care for your jewellery, and especially for your gemstone. We will gladly show you.
Gold is a soft metal, and it deserves to be worn thoughtfully: removed for sport and heavy work, kept away from chemicals, stored in its box. And once every couple of years, we recommend bringing your jewel to a jeweller so the prongs can be checked for wear; a five-minute inspection protects a stone for a lifetime.
