Stone Sourcing
We source GIA-certified natural and IGI-certified lab-grown diamonds
for every bespoke commission and engagement piece.
Our Sourcing Partner
For bespoke commissions — engagement rings, eternity bands, and one-of-a-kind pieces — Maison Olivané sources loose diamonds through Four Leaf Diamonds, a Dubai-based diamond dealer carrying GIA-certified natural diamonds and IGI-certified lab-grown stones across all major shapes and sizes.
You tell us the shape, carat weight, colour, and clarity you have in mind. We source the stone, present options with certificates, and build your piece around it. The entire process is private, guided, and unhurried.
Natural Mined Diamonds
The Gemological Institute of America — the world's most trusted diamond grading authority. Every natural stone we source carries a GIA certificate.
Lab-Grown Diamonds
The International Gemological Institute certifies lab-grown diamonds to the same standards as natural stones. Identical optical and physical properties at a fraction of the cost.
Available Shapes
All shapes are available in both natural (GIA) and lab-grown (IGI). Click any shape to view current stock on Four Leaf Diamonds, or contact us to request a specific stone.

View Stock →The Process
Share your preferred shape, approximate carat weight, colour grade, and clarity. If you are unsure, we guide you through the options.
We identify available stones from Four Leaf Diamonds' current inventory, present you with options and their certificates, and advise on the best value.
Once you select your diamond, we confirm the stone and begin designing your piece around it. The stone is reserved in your name.
Your piece is crafted in 18K gold, set with your chosen stone, and delivered to you within 3–4 weeks. Accompanied by the original certificate.
Understanding Your Stone
The most important factor. Cut determines how well a diamond reflects light — its brilliance, fire, and scintillation. We only source Excellent or Very Good cut grades.
Graded D (colourless) to Z (yellow). Maison Olivané collection pieces use D/E colour. For bespoke commissions, we advise F–G as an excellent balance of quality and value.
Refers to internal inclusions. VS1/VS2 (Very Slightly Included) is our standard — inclusions invisible to the naked eye, at a significant saving over Flawless grades.
Weight, not size. A well-cut 1ct diamond will appear larger than a poorly-cut 1.2ct stone. We help you find the best visual size for your budget.
