Victorian Old Mine Cut Cluster Signet Pinky Ring This Victorian-era cluster signet-style pinky ring features exceptionally chunky, sparkling Old Mine Cut diamonds that command attention. The center stone measures approximately 4 mm round by 2.5 mm deep, with an estimated weight of 0.35 carats. Surrounding it are Old Mine Cut accent diamonds ranging from 2.5–3.0 mm, each estimated between 0.04–0.10 carats. The total estimated carat weight for the ring falls between 0.67–1.15 carats, calculated by measurement. Due to the hand-cut nature of these antique diamonds, each stone varies in proportion, making a more precise total weight impossible to determine. Diamonds are estimated to be near colorless and SI-I eye clean clarity, small nibbles and nicks to the stones under magnification. Video of the ring is available for immediate viewing on our Instagram VanessaatHeritageJewelry The diamonds are set closely together in a rich yellow gold mount, beautifully engraved with crescent motifs—an exceptional example of Victorian craftsmanship and design. The interior is marked “18,” though gold testing indicates a range between 14–18k depending on the area tested. Currently a size 4.25 and able to be resized. The ring measures 12.10mm North to South at the widest point on the face and tapers to 2.93mm at the back of the band.

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 exceptional Art Deco engagement ring is centered by a true antique Old Mine Cut diamond, weighing 2.37 carats and certified natural by HRD (Cert. No. 240000231073). With its softly squared outline, generous depth, and open culet, the diamond displays the lively, “bubbly” facet pattern so beloved by admirers of antique cuts. The stone is 100% eye clean, graded SI1 clarity with a warm L color, and shows no fluorescence. 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.

Note: Stone specs are a jeweler’s approximate as precise measurement and assessment would require removing the diamond from the mount. This ring is so special. 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.
