Impactful glitter factor to this Georgian to early Victorian double row ring with boat or east west navette shape. This piece is in 18k gold and hallmarked as such, the diamonds are set in silver as was customary for the time, with a lot of antique patina. It also has a number hand engraved inside the shoulder - 189.

This could be polished up by it really makes the diamonds pop and most of my buyers prefer original patina. A lovely slight warmth to gray hue to the center two diamonds especially, and some slighter warmth to the others - often chosen intentionally by diamond cutters of the time and even sought after by antique collectors. It has a sort of untamed sparkle and texture, beautiful to wear.

Lovely engraved details at each shoulder.

Please note the measurements as I have small fingers and the pictures can make it difficult to see scale. Antique box is not included.

Size 7 1/2. The largest center diamonds are about 3mm tapering down to 2mm at the ends. I would not remove the stone for an accurate measurement but just using honesty, online estimates and calculators it is around 2/3 of a carat / 0.67ctw total weight estimated in diamonds.

The piece weighs 3.2 grams. It stands 4mm off the finger. Boat Ring face is 18mm by 8.4mm wide north to south.


All my pieces are pre owned and in estate condition. Lots of dark patina around the ring face. This one needs gentle wear because some of the prongs are quite worn. None of the stones move at all, but especially if you plan to have it sized - note that a modern jeweler will be alerting you to the worn prongs and to bend the ring in a sizing might require some reinforcement on some of the tips. Should you desire to have this done, I would recommend finding a jeweler with a laser welder as they can do more intircate work to the little prongs. It is currently in its original antique condition. About half the diamonds have a nick here or there. You can sometimes detect them with the eye if you catch the surface facet of the stone in a reflection, but they all appear complete and round to the eye. Typical antique diamonds with some faint natural inclusions, no carbon specks. But Due to age - please note this is not a mint condition item.

A note about antique diamonds:
The whole "4 C's" of cut, color, clarity, carat didn't come about until the 1940s so prior to that and especially on antique pieces, there was not as much emphasis placed on those things. (Sure people probably appreciated a certain look of a certain diamond as it appeared to the eye but it was not a graded scale like we have today.) So it is difficult to judge antique stones against modern day diamonds and their grading system. No two old cuts are the same as they were crafted in times lacking any modern standards. The diamond cutters of the time were experts at hand cutting each stone to enhance it which means that even lower color grades can be cut to appear whiter. It is also interesting that "lower graded" diamonds in today's scale system, were some of the best on the market during this period! So it is less about their grades and more about the unique play of light and color that each one can offer. I read one article that described: “When searching for the perfect old cut diamond (for you), you need to view them through different eyes as you would for a modern diamond. Laboratory grading reports don’t offer too much information in regards to the individual beauty or sparkle of an antique diamond. Antique diamonds are judged more on the individual character and uniqueness that each one potentially offers.”
