Description
This classic engagement ring features an emerald cut blue sapphire prong set in platinum, with a trapezoid diamond on either side completing the three-stone setting. It was created for a client from Bonney Lake, WA, who initially reached out to us online to share his ideas about the ring he wanted to make for his fiancee-to-be.
Read the full description
We discussed some options with him through the online workroom we created for the project, and he then came into our Bellevue, WA showroom to see some examples of our work in person. Once we had a good idea of what he was looking for, we created highly-detailed 3D models of his design, and he gave his approval to move the piece into production.
Three-stone Setting
The centerpiece of this ring is a 1.16 carat emerald cut blue sapphire, whose rich blue color contrasts beautifully with the sparkling white of the diamonds that make up the rest of the classic three-stone setting. The four platinum prongs holding the sapphire in place rise up in a trellis style from below, crossing over the prongs for the other stones in the process.
The way the strands of metal intertwine before rising up to wrap around the gemstones gives the piece a lovely, whimsical movement, and it brings just enough complexity to an otherwise minimalist design. The trapezoid shape of the side diamonds also helps ease the transition from the wider center stone to the narrower band, bringing a satisfying balance to the piece. Three Stone Engagement Rings
Gemstone and Metal Options
If you’d like to customize this design, there are plenty of options to consider. For instance, you could switch to a different type of metal like rose or yellow gold to add some vintage flair to the piece. You may also want to add some custom hand engraving or use a different setting style to help intensify that effect.
Another option could be to switch out all or some of the gemstones for a different type or color that has special meaning for you. Sapphires are available in many different shades, and you could also use all diamonds for a truly traditional look. Using a diamond in the center and colored stones on the side is possible as well, and no matter what type of style or look you’re going for, our team has the skills and experience to turn your vision into a beautiful reality.
