This superb Platinum Engagement or Cocktail ring from the Edwardian to early Art Deco era shows the mastery of gem-cutting and setting that jewelers attained in the early decades of the 20th century. This ring, with its elegant ‘Navette’ shape, is centered on a marquise-cut diamond, which is ingeniously surrounded by seamlessly set calibré-cut emeralds. Bordered by glittering circular-cut diamonds, this is a perfect example of a striking yet wearable early 20th century jewel. This ring is certainly among the most beautiful we have had to offer at Heritage Jewelry and it has been a delight to be able to admire such a piece of artistry in person. Our 0% Interest Layaway Plan makes it easy to plan for special occasions like anniversaries or holidays.

In my 30 years of collecting vintage jewelry I’ve never seen another ring like this one. It’s a vintage art nouveau Navette, pearl and diamond ring. The diamond is crisp and clear and bezel set with milgrain work. It’s 10 karat yellow gold with a triple split shank. Has graduated round pearls with a teardrop shape in the center. Size 8.5 and fully size able. It does appear a few pearls have been replaced. But it’s still a beautiful piece from the late 1800s. I found a stick pin that's $350. It's the only other piece I've seen remotely like this. I just can't wear pearls. I tend to put my rings on and wear them for months.

Tiffany & Co Platinum Diamond LUCIDA Engagement Ring 2.01 ct H SI1 GIA Cert Size 5.5 This is an authentic pre-owned Tiffany ring which has been freshly cleaned and polished. It comes with the GIA certificate, inner suede and outer cardboard Tiffany boxes. The diamond is laser inscribed "LUCIDA" per the GIA certificate. This is a natural, earth-mined diamond. This is a big, bold, stunning piece. The diamond is eye-clean, bright and white.

This is a one of a kind natural diamond ring. 9.8 grams 14kt yellow & White 2-toned gold. I purchased this years ago from a vintage shop on Etsy. Please review and enlarge photos to see the details of this ring. I loved it because it made me think of the Moon and all the stars in the sky (the small diamonds that are sent into the white gold section). I wore this sparingly only because I never did get it sized to my wedding finger. It is gorgeous but, I am ready to let it go and move on to other pieces now. If you have any interest in this ring. Please send me an offer. Gold value is around $626. One of a kind, and natural diamonds in Solid 14kt yellow gold with the inset of white gold section that also has natural diamonds set into it. Sized at a 6.5. Easily resizeable. *offers considered*

"The Rose" 2.92ctw GIA certified Old Mine Cut Diamond Ring A shop favorite is this stunningly beautiful Antique Past, Present, Future; 3 stone Engagement, or Wedding Ring. Stamped to the interior of the band and tested as Platinum. In excellent antique condition, ready to adorn a new finger with its graceful charm. We have included close up magnified photos so that you can better see the details of this delightful treasure. We have named this ring The Rose. Within the delicate pierce work and engraving roses adorn all sides of this ring. On either side of the main diamonds each North/South prong is a rendered Rose with a accent diamond to the center with trailing platinum leaves. On each shoulder there is a slightly different Rose design and another accent diamond.This original Edwardian era ring is so finely worked the ring appears delicate and airy in a way which simply is not cost effective to replicate in the modern era because of the amount of time it takes to execute such a work of art. If the setting were not enough beauty on its own the diamonds in this ring are the crowning achievement in antique handcut Old Mine Diamond excellence. Each is GIA certified and inscribed. The makes of the diamonds match exceedingly well with the culets reflecting within these excellent diamonds in what is known as Kozibe - a extremely desirable effect in some antique stones. We adore the pillowy cut of these diamonds. This heirloom ring is looking for a new finger to adorn with her one of a kind beauty. Currently a size 7 and able to be sized by a expert bench jeweler. An appraisal is included so that you may obtain insurance on your new ring. Video link available by request.

Bought from Filigree Jewelers in Rochester, MN, I have a for sale a center stone of a .5 ct round diamond in 14kt gold with beautiful pave diamonds and intricately detailed basket that holds the center diamond. This ring really sparkles like mad!!!! I’ve worn this ring as a right hand ring infrequently, but anyone can easily use this as an engagement ring. I’m just seeing if there’s any interest. I love this ring, but I never wear it. I’d love someone else to love it as much as I do and actually wear it. I bought this ring for $3,400. Size 6. The diamond is super bright (DEF) and eye and loupe clean. All sales final. I’d be happy to send more pics or a video of this baby sparkle. If I don’t respond through Loupetroop, email me at laurakos@yahoo.com. I accept PayPal or Venmo. Thanks for looking!

I purchased this ring a couple years ago from Dolly on Instagram (xothebijouxbox). Check out her stuff! She finds amazing pieces. While I absolutely love this ring, I never wear it. It deserves to be worn. Size 6. 14 kt white gold. Under .5 ct diamond center (not by much, but I'm unaware of the exact ct weight of the center stone). The diamonds appear to be colorless and inclusion free. I can't see anything with the naked eye or my loupe. It's truly a gorgeous, sparkly piece with a center diamond you get lost in (it's that pretty). All natural diamonds. Open to reasonable offers. Payment via PayPal with the buyer to pay PayPal fees if paying via goods and services or Venmo. Free insured shipping in the US only via Priority Mail. If you do not get a response within a couple of hours, please email me at laurakos@yahoo.com. I am a prive seller; therefore, all sales are final. No returns or refunds, full or partial. Ring is sold as is - with no damage to the diamond or setting. I will polish and clean before I ship it.
