Custom Trillion 3 Stone Engagement Ring
Our Trillion 3 Stone Engagement Ring offers an unusual interpretation of the traditional three-stone design. Featuring three triangular gemstones, a semi-tension center setting, and bezel-set side stones, this ring combines bold geometric shapes with contrasting setting styles.
The pictured design features a 6 mm trillion-cut center gemstone flanked by two smaller trillion stones. The original arrangement uses contrasting yellow and white gemstones, creating an eye-catching combination of shapes and colors.
Unlike traditional three-stone rings with round diamonds and conventional prong settings, this design emphasizes the sharp angles of the trillion cuts and the sculpted metalwork surrounding them.
At Valeria Custom Jewelry, we can recreate the original ring or customize the gemstone colors, dimensions, and settings to create something entirely different.
A Semi-Tension Set Trillion Center Stone
The center gemstone is the focal point of this engagement ring.
A 6 mm trillion-cut stone sits within a semi-tension setting, giving the appearance of being held between sections of the ring rather than surrounded by a conventional prong basket.
The triangular shape complements the contemporary design, while the setting creates an open, sculptural appearance.
Unlike a true tension setting, a semi-tension design incorporates additional structural support to secure the gemstone.
We can adjust the center stone size, modify the surrounding metalwork, or develop a different setting arrangement depending on your preferred gemstone and its dimensions.
Bezel-Set Trillion Side Stones
Two smaller trillion-cut gemstones flank the center, each surrounded by a bezel setting.
These settings emphasize the triangular outlines of the side stones and create a visual contrast with the more open center setting.
The pictured design uses contrasting gemstone colors, but all three stones can match or feature entirely different colors.
A white diamond center with yellow diamond accents is one possibility. Other combinations could incorporate sapphires, moissanite, or suitable colored gemstones.
The center-to-side stone proportions can also be adjusted. Larger side stones create a broader three-stone arrangement, while smaller accents place greater emphasis on the center.
