Our Commitment to Quality & Authenticity
At Bijoux de Chagall, every piece we create is held to the highest standards of gemological integrity, ethical sourcing, and fine craftsmanship. This page sets out exactly what we guarantee - so you can wear your jewellery with complete confidence.
Diamond Luxury: Master Cut Surface Spread
At Bijoux de Chagall, we believe your investment should shine entirely on display - not remain hidden out of sight. Traditional Diamond cuts often carry up to half of their total carat weight deep beneath the metal setting in the 'belly' of the stone. Our Master Cut Maximum Spread deliberately optimize the depth profile of our ethically sourced Diamonds to create an exceptional, wider face-up look.
By strategically expanding the surface dimension, a 1ct Oval Diamond boasts a majestic 8mm x 5.5mm face size - effortlessly delivering the spectacular, show-stopping hand presence typically reserved for traditional rings twice its weight. Crafted for the modern romantics, this brilliant engineering ensures Maximum Visual Impact and structural elegance, beautifully handcrafted for an enduring heirloom.
Your Diamond, Your Choice
At Bijoux de Chagall, we believe that exceptional jewellery should celebrate individuality, beauty and respect for our planet.
We offer beautiful lab-grown Diamonds as a thoughtful, Eco-conscious alternative to traditional Diamond mining.
Traditional diamond mining can carry significant environmental consequences, from deforestation and the destruction of natural habitats to the disruption of delicate ecosystems and threats to biodiversity. Forests, wildlife and the natural environments that countless species depend upon can all be affected by mining activities.
This is one of the reasons we embrace lab-grown diamonds as a thoughtful alternative. They offer the same chemical composition, physical properties and captivating brilliance as natural diamonds, without requiring the excavation of new diamond deposits. Their production still requires energy and resources, but they avoid the direct habitat destruction associated with diamond extraction.
We also respect that every customer has their own preferences. For those who would prefer a natural mined diamond, we are delighted to offer a bespoke Diamond sourcing service for many of our engagement ring designs.
Looking for a different Diamond option?
Whether you prefer a lab-grown or natural Diamond, we can explore your desired shape, size, quality and budget to help create a ring that feels truly personal.
Please contact us to discuss your preferences and request a personalised quotation. Bespoke Diamond options are subject to availability and individual pricing.
IGI DIAMONDS CERTIFICATE
Diamonds above 4mm in size with standard faceted cuts are independently IGI certified (by International Gemmological Institute), with certification included in the price.
Every IGI-certified diamond includes a unique certificate number that is microscopically laser-inscribed on the diamond, allowing it to be matched to its official IGI grading report.
Smaller diamonds (under 4mm), as well as rustic, rose-cut, rock, and salt & pepper diamonds, are not typically certified, as their characteristics and structure differ from standard grading criteria.
Each is selected for its unique character and carefully assessed for quality and authenticity before being set into your jewellery.
WGI GEMSTONES CERTIFICATE
At Bijoux de Chagall, all gemstones are sourced from reputable, officially recognised suppliers and are carefully examined for quality and authenticity before being set into your jewellery.
Our gemstones can be independently certified by the World Gemological Institute (WGI). This optional service provides independent identification and documentation for customers who would like additional independent third-party verification of their gemstone.
In all cases, we are committed to complete transparency and selecting each stone with care, integrity, and respect for its natural beauty.
Lab-Grown Diamonds & Gemstones - Genuine and Real
All lab-grown diamonds and gemstones used at Bijoux de Chagall are real, genuine gemstones - not imitations. They are created using advanced technology that replicates the conditions in which gemstones form in nature, giving them the same essential chemical and physical properties, brilliance and durability as their mined counterparts.
They should never be confused with simulants or imitation stones, such as cubic zirconia, which only replicate appearance. Our lab-grown stones are true fine jewellery gems, carefully selected for their beauty and integrity, and perfectly suited to meaningful pieces designed to last a lifetime.
We are proud to choose lab-grown gemstones. We see them as a revolutionary development in modern jewellery: beautiful precious materials created through advanced technology without the need to extract every new stone from the Earth.
For us, this is an important environmental Eco choice. Traditional gemstone and diamond mining can involve extensive land disturbance, resource use and environmental impact. Choosing lab-grown stones allows us to reduce our reliance on newly mined gemstones while embracing innovation and a more environmentally conscious approach to fine jewellery.
They offer a more environmentally conscious alternative to traditional mining, without compromising on quality or authenticity.
We believe it is time to rethink the traditional idea that a gemstone must be taken from the Earth to be precious. Beauty, craftsmanship, meaning and love are not defined by a mine.
