Video: https://imgur.com/a/VbpB3wd This is an antique rose cut diamond ring from France. It feautures a large 7.5mm x 6.4mm rose cut diamond that is set in a double bezel-prong setting. Genuine antique rose cuts of this size are very hard to find. Originally the stone was set in a closed back silver setting, however, there was some dirt, so the setting was re-done using a platinum backing, which will never tarnish. The shank is 18k rose gold. There is a faded hallmark on the back of the band, but it is likely the French eagle hallmark. The weight is 2.2 grams and the size is 5; it can be easily resized however. For payment, I use Square invoices. Venmo & Zelle is fine as well.

For your consideration is a beautiful 5 stone natural diamond engagement and wedding band set. The center diamond is a 0.6 carat round brilliant diamond and it is matched with 4 0.10 carat tapered baguette diamonds for a total 1.0 carat weight. This ring sparkles tremendously—more than I can fully capture with my phone. The band and ring are 6.5 and solid 14k yellow gold. The prongs are 14k white gold. They are not soldered together so they can be worn as a set or separately. However, the band has a custom dip so that it sits flush against the engagement ring in very pretty way. The center diamond is GIA certified and the certificate will be included. The cut is very good and the ring sparkles equivalently to excellent cut diamonds—I have received many compliments and surprised many by its size because the diamonds really sparkle and look well sized. The diamond is S12 though the inclusions are hidden by the prongs. The center diamond is a natural diamond that was HPHT treated to F color. The baguettes are F in color and the combined effect is an icy, sparkly set. This is a wonderful set at a very good price (less than the appraised and insured value). The appraisal and GIA paperwork are included. Please contact me with any questions and offers. I am happy to take more photographs to best of my iPhone’s capacity. Thank you!

**Will entertain all offers!** Putting out feelers for this set. I would rather them sell together but willing to sell separately to get them sold! E-ring is .82 ct, AGS, K VVS2, and medium blue Fluor! One of THE BEST K’s I’ve seen! Don’t let the color scare you off! Both rings are 14k and size 7 3/4. Both are low profile and 1.5 mm wide. Both are half eternity, so if you need them to be sized, I’m sure it wouldn’t be an issue. The setting/band were purchased through BlushKarats on Etsy. If you have an offer for the band or Ering separately, feel free to email me. Set has barely ever been worn. I just don’t reach for it. Pictures are horrible, so if you need a video or better close ups please feel free to reach out! Ering is amazing and is white for its grade! I have sold here many times and have been a pricescope member for years. If you are looking for an affordable knock your socks off ering/band set, this is it! Looks way more expensive than asking price! I will pay for priority shipping within US only. PayPal FF or goods and services, but I will ask you cover the fee. No returns as this is a private sale. Thank you!

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.

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.

I affectionately call this piece "pink sugar," because that's exactly what it looks like to me. I believe the diamond color is 7P... so they will look something like the below image in person. They're not deeply saturated, obviously, but distinctly pink. No brown, orange, or purple. Clarity and cut are excellent... VS, ideal. Total carat weight is approximately 1.275ctw. There are forty-eight 1.5mm stones (.015ct each), twelve 1.7mm stones (.020ct each), and nine 2mm stones (.035ct each). Ring measures about 13mm long (north-south) and is finished in solid 14k rose gold. This may be the sparkliest ring I've ever sold. It's incredibly beautiful in person. Size 6 US (resizable). I paid: $14,990 (very old price) You'll pay: $9,990

I am selling a never-worn ring purchased from angel alchemy jewelry. This crescent moon dreamcatcher ring is done in solid 14k yellow gold. The diamonds are clear and sparkly. It’s a size 7.25, but can be resized by any local jeweler. It was $1450 when i purchased it 2 years ago. This is the large version of the diamond dreamcatcher ring. It always sells out in a flash when it comes back in stock. Mandy only makes jewelry in small batches, so this design only shows up from time to time. Her jewelry is well made and never flimsy. Sale is final. Shipping is included within the states. Not sure if messaging is wonky. You can contact me direct at dchicago8 at gmail
