Classic three stone old mine cut diamond ring in 18k gold. It is set with the old mine cut diamonds totaling just under 1 full carat (about 0.95). Layers well with other pieces. This one is currently a large finger size but with prongs in good shape making it eligible for sizing by your local jeweler.

British in origin with hallmarks for 18k gold but I can't make out the date mark. The worn maker's mark looks older. It could be a case where grandma's 1800s diamonds were reset in the early 20th century.

The diamonds are clearly hand cut with an almost free form, organic appearance. The center stone especially is somewhat oblong which adds such a fun antique character compared to perfectly round modern machine cut diamonds that are cut by the millions each year. These old chunks have withstood the test of time.

Please note the measurements as I have small fingers and it can be difficult to determine scale from the pics.

Antique boxes, props, mice, staircases and bannisters ; ) not included.

Size: 10 - the prongs are in good enough shape to make it eligible for sizing. Usually they say within 2 sizes is a good guide but best to discuss with your local jeweler who would be doing the work as opinions vary.
Weight: 3.2g
Height off the finger: 5.7mm

The diamonds are around 4.2mm each, cushion cut with varying depths but chunky cuts with thicker girdles. I would never remove them for an exact measurement but calculates to around .95 carat for the 3 of them.

Typical antique diamonds with a slight warmth in color, one of the three being whiter than the others at one end, and at the other end being the warmest and chunkiest cut. Although you may notice in some of the pictures how the side stones reflect the light differently because they are splayed outward and do not "face up" like the center stone which is perfectly perpendicular from the ring face to the eye view. In that case the variation you see is just looking at the stone from the side, and then once the hand is turned so that the side stones face up, they appear whiter again. A fun fact about expertly hand cut old mine diamonds! The warmth is also emphasized when the piece is seen in direct sunlight.

Also typical for antique stones, one of the end stones, the whitest one, has a web of frosty crystal and tiny carbon speck inclusions along half of the outside facets. The carbon specks are not very apparent but the frosty inclusions can catch the light. The culet is off center so you can see how the diamond cutter worked around that over 100 years ago. The other two stones are eye clean with only faint natural inclusions seen under magnification. But I considered all these things in the pricing, they are nice chunky old cuts.

A worn prong here are there but enough remain on each side to hold all stones securely. Typical and expected for age - Just something to keep an eye on over time.

Please note that all my pieces are pre-owned and in estate condition. They will have patina, surface wear, a few small nicks. These pieces may also have evidence of a sizing, some build up around the stones and / or inclusions seen under magnification, typical for antique pieces. I have mentioned any noticeable issues above and they are all still wearable and eager to be loved and accepted for many years to come, (the preservation of antique jewelry, even those with signs of their age and history, is important to me. : )
But - Please note due to age, this piece is not in mint condition. Pictures also serve as part of the description and condition report so please utilize the zoom feature which will magnify any wear significantly more than what is visible to the eye while wearing : )
