This 7.4 mm round three stone engagement ring mounting features a brilliant round center setting, flanked by four graduated round side stones on each side.

Choose from solid 9K, 14K, 18K gold or platinum for this setting. Every metal option is responsibly sourced and thoroughly inspected to ensure a consistent finish and long-lasting durability. Each ring base is handcrafted by skilled artisans and polished to perfection in small production runs to maintain precision.

Whether you need a one piece custom engagement ring or a small batch for your brand, we ensure full CAD rendering and design support.
Perfect Gift for Any Occasion
This setting makes a meaningful base for a proposal ring, anniversary gift, or heirloom remake. Its classic three-stone layout symbolizes past, present, and future — a sentimental choice for life’s important milestones. Pair it with a lab-grown or natural diamond to complete your story.
