Product details
Elegant yet structured, the Aveline Cushion Cathedral Three-Stone Engagement Ring offers a harmonious blend of timeless charm and architectural beauty. At its centre, a glowing cushion-cut lab-grown diamond or moissanite radiates soft brilliance, flanked by two 4mm round side stones for a look that balances classic proportions with modern sophistication.
The cathedral-style setting lifts the centre stone above the band with refined grace, allowing light to flow freely beneath. Delicate claw prongs and a shimmering pavé band add further dimension and brilliance, while the 0.5ct of round-cut side stones deliver a clean, symmetrical frame.
Crafted in your choice of 14K or 18K yellow, white, or rose gold, or platinum, this ring is available in 1.5mm, 1.8mm, or 2mm widths. The 6.7mm setting height (with a 2 carat centre) ensures presence without compromising comfort, while the 1.7mm band height allows for seamless stacking and easy everyday wear.

More Info
Every engagement ring is crafted with precision and care, ensuring that any side stones perfectly match the chosen main stone in quality and colour—unless a custom colour is requested. Our rings typically weigh between 3 to 5 grams, depending on the design, ring size, and metal type.
The average production time is 3-4 weeks after payment, as each piece is meticulously handcrafted to perfection. We use only the finest materials, ensuring a balance of durability and elegance. For a truly bespoke experience, each ring is made to order, allowing for the highest level of craftsmanship and attention to detail. If you require further customization, our expert jewellers are available to assist in bringing your vision to life.
Rings with pavé-set stones or gemstones along the band cannot be resized, as adjustments may compromise the setting. Designs with unique shapes or intricate band structures may also be non-resizable. Simple bands can typically be resized up or down by 2-3 sizes, while certain delicate styles may only allow for a half-size adjustment. Ensure you select the correct size when purchasing these designs, as resizing may not be possible.
