I have had this Kwiat ring for a while, and it’s one of the most blingy and sparkly piece of jewelry I have ever owned. But I *think* I am ready to let it go. It has always been loose on me. Now my finger size has changed so it is every looser! I never get around to sizing things either. It has almost 2 carats of beautiful stones and is 10 grams of 18k gold (which, in today’s gold prices – egad). So I am offering it up for sale here. It is a size 6 on my mandrel (see photos) but since it is a thicker band I believe would be comfy on 5.75. It is approx 11.8mm wide at the widest part and 6.8mm at the smallest (in the back). This ring is just full of fire and sparkle. It is amazing and retails for over 8k so I am offering it for a very competitive price. Sales are final. Add 3% if using PP G&S.

This beautiful engagement ring is a true shop favorite, cherished for its graceful proportions and beautiful floral design. Recently returned from certification and expert restoration, it is now ready to be loved for another lifetime. At the heart of the ring rests a completely eye-clean Old European Cut diamond, sparkling with the soft, romantic light that only an antique cut can offer. The diamond’s character-rich faceting creates large flashes of brilliance, while its medium culet and small table speak to the artistry of a bygone era. Though graded I1, the only clarity feature is a delicate edge feather so well concealed within the faceting that it took magnification and a jeweler’s loupe to locate—the stone is both beautifully clean and bright to the naked eye. The diamond is framed by an exquisite floral setting crafted by the renowned Belais workshop, celebrated for its refined metalwork and pioneering use of white gold. Two custom-cut triangular blue sapphires accent the design, adding a subtle yet striking touch of color that enhances the ring’s romantic presence without overwhelming its delicate balance. Elegant, feminine, and rich with history, this ring is a timeless expression of love—thoughtfully restored, beautifully preserved, and ready to begin its next chapter. In person viewings are available by appointment at our Edmond, Ok office. 0% Interest Layaway Plans up to 7 months make it easy to plan for special events such as anniversaries, birthdays and holidays! Video available by request. www.HeritageJewelry.com Historical Note Belais Manufacturing Co., founded by David Belais, was a pioneering American jewelry firm and among the earliest producers of white gold jewelry in the United States. In the late 19th and early 20th centuries, Belais experimented extensively with white gold alloys as an alternative to platinum, since platinum was restricted due to wartime demands during WW1. In 1917, David Belais introduced his final white gold formula to the trade, and a patent was granted in 1920. The resulting 18-karat alloy—composed of gold, zinc, and nickel—proved both durable and practical, quickly earning widespread acclaim. Belais’ marketing success was so significant that the name “Belais” became nearly synonymous with white gold, reinforced by the company’s well-known slogan, “Belais Made Means Well Made.” Beyond jewelry, David Belais was also the founder of the Humane Society of New York in 1904 and a lifelong advocate for animal welfare, serving as its president until his death.

Measuring 7.84 × 7.77 × 5.81 mm, it has a pleasing 51% table and very good polish, contributing to its distinctive old-world character. Surrounding the center stone are twenty sparkling Old European–cut accent diamonds, each with a visible culet and weighing approximately 0.02 to 0.03 carats, along with vivid green baguette-cut emerald green accents measuring approximately 0.03 carats each. Together, they create a dynamic interplay of light and color that is quintessentially Art Deco. Crafted in platinum, the ring is designed to sit close to the finger with a graceful, low profile, making it exceptionally comfortable for daily wear and especially practical for those who wear gloves. The luxurious platinum setting enhances the brightness of the diamonds while allowing the Old Mine Cut center stone to shine. The ring is currently a size 9.5 and may be resized. A striking and uncommon combination of a substantial antique Old Mine Cut diamond, period accent stones, and thoughtful design, this ring is a standout example of early 20th-century craftsmanship—rich in character, wearable elegance, and timeless appeal.

I am 100% a yellow gold girly but this was the one white gold ring that just made me feeeel thingsss and I had to have it. The main diamond is a substantial 1 CT old mine cut, with a touch of warmth characteristic of antique stones. I adore the pillowy cut and chunky high crown. Together with the intricate filigree hand engraved details, this ring just feels so romantic. I’m letting it go because as much as I absolutely love this ring, my entire collection is in yellow gold, so I never get the opportunity to wear it or match it with other pieces - and this antique beauty deserves to be shown off. Asking price is what I paid several years ago + shipping & fees. Gold price has almost tripled in that time, but I’m not looking to make a profit on this personal piece, only to recoup what I paid and have this beauty find a new loving home.
