Product details

Description

Sculptural minimalism meets timeless elegance in the Alosta Oval East-West Half Bezel Engagement Ring. Designed for those who appreciate a clean silhouette with architectural precision, this modern solitaire sets the oval-cut centre stone in a sleek east-west orientation, secured by two end bezels rather than the traditional side-set bezel. This unique layout leaves the elongated stone fully visible from the sides, allowing light to pass through and enhance its brilliance.

The Alosta’s band features a refined, slightly flattened profile for a contemporary look and comfortable fit. With a streamlined setting height of 5.5 mm, this ring offers both bold visual impact and practicality for everyday wear. Available in your choice of 14K or 18K gold or platinum, and set with your preferred lab-grown diamond or moissanite, the Alosta is a refined departure from the expected — perfect for the modern romantic.

Whether worn solo or stacked with a matching band, this design celebrates form, light, and originality.

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.
