Fancy-Shape and Fancy-Colour Lab-Grown Diamonds

Elmonas's fancy-shape and fancy-colour lab-grown diamonds are selected or developed for distinctive jewellery designs that require a specific outline, colour effect, or visual identity. The page is for buyers looking beyond standard rounds for pear, oval, marquise, emerald, radiant, cushion, heart, and other design-specific shapes, as well as colour-led stones.

Key facts

• Certification: IGI certification can be requested where applicable; treatment and colour-origin disclosure should be agreed for each brief.
• Tolerance range: On request; measurement and matching tolerances are agreed in writing for each order before selection or production.
• MOQ: no minimum order for stones 2 carats and above; 10 carats total minimum when individual stones are below 2 carats.
• Lead time: On request; timing is confirmed at quotation with the production stages for each order.
• Primary shapes: pear, oval, marquise, emerald, radiant, cushion, heart, and other agreed fancy shapes; colour requirements by brief.

Fancy shapes are judged in context. Length-to-width relationship, outline, corners, facet pattern, symmetry, bow-tie appearance, windowing, and face-up spread can affect how a stone works in a mounting. For a layout or pair, the brief should state whether outline, measurements, orientation, or visual balance is the primary acceptance criterion.

Fancy colour requires clear disclosure. HPHT can be useful for certain blue, yellow, and treated colours, while CVD and treatment combinations can support other outcomes. Method does not determine marketability by itself. Buyers should require information about colour origin and post-growth treatment, then review the finished colour, distribution, and relevant report comments.[1]

Share the target shape, measurements, colour description, clarity range, quantity, setting constraints, and reference image or CAD file. Available rough and required yield may influence a custom outline and its economics. A preliminary discussion can identify which design features must be protected and which preferences can flex.
