Product details
The Seraphine Oval Three-Stone Engagement Ring is a timeless and sophisticated design, featuring an oval-cut lab-grown diamond or moissanite flanked by two tapered baguette side stones. The 4.25 x 2.25 x 1.5mm baguettes elegantly frame the elongated center stone, enhancing its brilliance while creating a sleek, refined silhouette.
Designed for both beauty and comfort, the low-profile setting ensures an effortless fit for everyday wear. The 1.5mm, 1.8mm, or 2mm band is adorned with delicate pavé accents totaling 0.18 carats, adding subtle shimmer without distracting from the three-stone design. With a total side stone weight of 0.15 tcw, this ring embodies the perfect balance of brilliance and modern sophistication.
Customize your Seraphine Oval Three-Stone Engagement Ring in 14K or 18K white, yellow, or rose gold, or platinum, for a refined, ethically crafted engagement ring that blends classic elegance with contemporary luxury.
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.
