18K Yellow & White Three Stone Ring Setting

This three stone ring setting is designed to symbolize the past, present, and future, placing a prominent center gemstone between two Asscher cut octagon diamond side stones, creating a composition that is both meaningful and elegantly restrained. The setting is fully custom made, available in 14K Rose Gold, 18K Rose Gold, 14K White Gold, 18K White Gold, 14K Yellow Gold, 18K Yellow Gold, Platinum 950, 14K two tone white and yellow, 18K two tone white and yellow, 14K yellow and white, and 18K yellow and white, allowing clients to match metal warmth and durability to their lifestyle and colored center stone choice. Center stones can be sapphire, ruby, emerald, or a custom gem of choice, and each gem choice carries specific grading and origin considerations. For colored stones I recommend natural corundum sapphires from Sri Lanka, Madagascar, or Kashmir for their saturated hue and toughness, rubies from Myanmar or Mozambique for their red saturation and rarity, and emeralds from Colombia or Zambia for their vivid green and classic appeal, noting that emeralds commonly exhibit natural fissures and oil treatments which should be disclosed and documented. Side diamonds in Asscher octagon shape perform best when graded with high clarity and good color, because the step cut reveals inclusions more readily, so I advise selecting VS2 or better for clarity and H color or better when set in white metals, while I allow a slightly warmer color grade with rose or yellow gold to optimize value without compromising visual balance. GIA or IGI certification is recommended for both center and side stones to ensure provenance and accurate grading.

Structurally this three stone setting provides an ideal balance of strength and a delicate appearance, the solid shank and reinforced gallery provide long term wear resistance while the open prong architecture around the center seat allows light to enter the pavilion for maximum brilliance without adding bulk. Compared to halo settings which create more surface area and can be more delicate to service, this three stone design offers greater security with individually pronged side diamonds and a guarded central seat, yet reads visually lighter and more refined than heavy channel or bezel styles that prioritize protection over optical openness. For educated buyers concerned with maintenance and longevity, the prong count and prong thickness can be specified to match lifestyle needs, and metal hardness choices such as 18K gold or Platinum 950 provide superior scratch resistance for daily wear. This setting pairs classical symbolism with gemological best practices, making it an excellent choice for someone seeking beauty, provenance, and lasting structural integrity.
