Low profile rings suit those who want beauty without bulk. This flush set ruby sits embedded in the band at metal level, protected from daily wear while displaying rich red color through its polished surface.
The filigree twist pattern flows along the 3.25mm band, adding handcrafted texture that catches light from every angle. Yellow gold ruby rings create a classic pairing, the warm metal enhancing the stone's natural fire.
Ruby scores 9 on the Mohs hardness scale, making it one of the most durable colored gemstones available. This unique promise ring works equally well as an alternative engagement ring or meaningful gift for anniversaries and milestones.
Personalized couple rings can feature different center stones for each partner. Available in 18K yellow gold, white gold, rose gold, or sterling silver.
Choose a different center stone if you prefer, or add engraving inside the band. Upload your own handwriting to create something truly personal.

Craftsmanship
Barcelona artisan jewelry honors ancient techniques while creating pieces for modern life. Our craftsmen hand-form each filigree twist from precious metal wire, then prepare the band for flush setting by drilling and shaping the seat with exact precision.
The ruby is placed and the surrounding metal carefully pushed to secure it at perfect level. This custom jewelry from Barcelona demands skilled hands and patient attention, resulting in a ring built to last generations.
Q/A
Q: What does a ruby symbolize in a promise ring?
Ruby represents passion, love, and deep commitment. Throughout history, rubies have been called the stone of the heart, believed to strengthen emotional bonds between partners. Choosing ruby for a promise ring adds layers of meaning beyond simple beauty.
Q: How durable is ruby for everyday wear?
Extremely durable. Ruby scores 9 on the Mohs hardness scale, second only to diamond. Combined with the protective flush setting that embeds the stone into the band, this ring handles daily activities with confidence. No protruding stone to catch or chip.
Q: What is a flush set ring and why choose it?
Flush setting embeds the gemstone directly into the metal so it sits level with the band surface. This protects the stone from impacts and snags, making it ideal for active lifestyles. The sleek, low profile design also appeals to those who prefer minimalist jewelry.
Q: Can I customize the gemstone or metal?
Yes. While shown with ruby in yellow gold, we offer many combinations. Choose sapphire, morganite, diamond, or other gemstones. Select from yellow gold, rose gold, white gold, or sterling silver. Engrave inside with text or your own handwriting.
Q: How do I find my correct ring size?
Professional measurement is essential. Printable sizers and string methods are often inaccurate. Visit a local jeweler, or order our professional ring sizer (https://www.cadijewelry.com/products/ring-sizer-with-free-express-shipping) with express shipping. We fully credit the sizer cost when you purchase.
Q: Is ruby a good alternative to diamond for a promise ring?
Many couples prefer ruby for its vibrant color and romantic symbolism. While diamonds represent tradition, rubies offer personal expression and stand out from conventional choices. With comparable hardness and durability, ruby makes an excellent choice for rings worn every day.
Very well crafted and beautiful ring. Maya and Eliad were also most helpful in answering queries and provide lots of guidance to help you make a decision. Excellent service!

I had such a great experience with Maya and this store. I had some difficulties but Maya was extermely helpful and kind throughout my experience. After I ordered the ring I was kept in contact with throughout the process which is super important, especially for a wedding ring. But when it arrived I realised I'd ordered the wrong size (my fault not the sellers!) and when I explained this to Maya I was told I could return my own ring and would be made a new one with only postage costs. I found this kind of customer service to be overwhealming. I highly recommend working with this store and I'm extremely happy with the finished product. My ring is beautiful!Thank you!!

I ordered a set of rings for my husband and I after my wedding rings were stolen. I emailed the shop owners with questions after seeing this ring and LOVING it and received a reply almost instantly! These wonderful people worked with me from the very beginning. From making these rings exactly like I wanted so that they would be a precious and special part of our relationship to sending me updates about the status so I wouldn't go crazy waiting :) I could not be happier with these beautiful rings. Maya and Eliad made sure that my rings were completed and to me by our special day and they are perfect. The sizing was dead on and the rose gold is gorgeous!! I can't thank Maya and Eliad enough for making the perfect rings for my husband and I. I would recommend these artists to anyone knowing the work will be A++!<3
