IGI DIAMONDS CERTIFICATE
Diamonds above 4mm in size with standard faceted cuts are IGI certified (by International Gemmological Institute), with certification included in the price.
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.
Many of our gemstones are WGI certified by the World Gemological Institute, providing independent verification of their characteristics.
For certain well-known and widely recognised gemstones, such as Moss Agate, Pearls, Opals or Kyanite, certification is not typically required, as their properties are easily identifiable and universally understood within the trade.
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 Identical
All Lab-grown Diamonds and Gemstones used at Bijoux de Chagall are geologically, chemically and physically identical to their natural counterparts. They are real gemstones, created in controlled conditions that replicate nature’s process, with the same structure, brilliance and durability as mined stones.
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 for meaningful pieces designed to last a lifetime.
In addition, they offer a more environmentally conscious alternative to traditional mining, without compromising on quality or authenticity.
