While most natural diamonds on the market today are technically compliant with the Kimberley Process Certification Scheme (KPCS), the UN-backed system created to prevent the trade of conflict diamonds, the KPCS has important limitations.

Many diamonds are still sold in mixed-origin lots, which means stones from multiple countries are combined and redistributed without individual provenance. Even when a parcel is labeled “conflict-free,” the specific mine or country of origin often isn’t documented, and the KPCS does not address broader ethical issues such as labor practices, environmental impact, or community welfare.

We believe in a more transparent approach to sourcing. Whenever a diamond is accompanied by verified mine-to-market documentation, its origin is clearly disclosed. When a diamond’s origin is unknown, as is common within the global natural diamond supply, we state that openly as well. As for our smaller (melee) natural diamonds, the exact geographic origin is unknown, unless specifically stated, as they are sourced through established global supply channels where full traceability is not always possible. This approach allows us to offer a thoughtfully curated range of ethically sourced, responsibly vetted stones across varying budgets, including more accessible options where documented origin is unavailable.

Our priority is honest communication: whether a diamond’s origin is traceable or not, we will always tell you exactly what we know so you can choose the stone that aligns with your values.

Natural and lab-grown diamonds are chemically and visually identical: both are real diamonds made of pure carbon. The main difference lies in their formation. Natural diamonds form over billions of years deep within the Earth, while lab-grown diamonds are created using advanced technology that replicates those same conditions in a controlled environment.

At MAIA & LYRA, we offer both options: naturally formed diamonds for those who value geological rarity, and lab-grown diamonds for couples who prefer sustainability, traceability, or a larger stone within the same budget.

Lab-grown diamonds generally have a lower environmental impact because they don’t require large-scale mining, and many are produced using energy-efficient methods. Some lab diamonds — including SCS-007 certified stones — go a step further by meeting strict standards for traceability, climate neutrality, and responsible manufacturing.

We do our very best to select lab-grown diamonds from trusted partners who prioritize sustainability, transparency, and ethical production with an SCS certification so you know your stone aligns with your values.

Lab-grown diamonds offer incredible beauty, brilliance and size for the price, but they typically have a lower long-term resale value compared to natural diamonds. Many couples choose lab-grown stones because they prioritize affordablility and carat size without compromising quality.

We encourage clients to choose the diamond that best reflects their priorities: natural diamonds for geological rarity and traditional value, or lab-grown diamonds for modern ethics and budget-friendly luxury. There’s no “right” choice: just the one that fits your love story.

Moissanite has a unique origin story. First discovered in 1893 within a meteor crater by scientist Henri Moissan, natural moissanite is exceptionally rare and not available in quantities suitable for jewelry production. As a result, all moissanite used in fine jewelry today is lab-created, allowing its optical properties and durability to be reliably replicated.

At MAIA + LYRA, moissanite may be offered by request for made-to-order or bespoke designs. While our primary focus remains on natural gemstones and natural or lab diamonds, we understand that moissanite holds meaning for some clients and are happy to accommodate thoughtful requests when aligned with the design.

Yes. We work with natural gemstones only, carefully selected for their character, rarity, and individuality. We do not offer lab-grown gemstones, as we are drawn to the organic variations and timeless beauty found naturally in gemstones.
