A unique and sturdy one of a kind ring that we affectionately call the snowflake ring!

The 14 chunky old mine cuts are set in platinum prongs and nested in the shape of a snowflake or starburst pattern between the flared and scalloped details of the chunky 18k gold setting. This is an amazing statement piece totaling around 2 carats in old mine cut diamonds, with a very heavy hand feel of 16.3 grams. It takes up a lot of real estate on the finger and provides a lot of drama with the glowing gold work bowing up to catch the light and glimmer as a rich backdrop to the sparkly old cut diamonds. I haven't seen one like it.

Found in Paris, this piece has French hallmarks for 18k gold and platinum. The gold has a warm, rich patina with rosy hues from age, not the vibrant pink rose gold of today. Very sturdy setting ready for regular wear.

Please note the measurements as I have small fingers and it can be difficult to determine scale from pictures.
Antique box not included.

Size 6 3/4. The ring face 20mm (over 3/4 inch) north south and it's about the same east to west. It is 8.3mm tall off the finger with the high crown of the diamond. It weighs a very sturdy 16.3g.

I do not remove my stones from their antique settings for exact measurements and the stone depths vary, but it was sold to me from a reputable source at around 2 carats total weight in diamonds with the center stone being around .6 carat according to their measurements. The center diamond is about 4.5mm with a very chunky cut with high crown / deep pavilion. The thirteen diamonds in the halos are 2.3 to 3mm each again very chunky cuts. One of the outside diamonds is an old European cut but I think it is still original to the piece, it just has a shorter crown and is a bit more round.


All my pieces are pre-owned and in estate condition. The center diamond has four indented natural inclusions on the underside of the stone around and into the culet. GIA defines this as a dent that occurs under the surface of a diamond as a result of the diamond cutter's decision not to polish it off, because doing so could end up harming the diamond so the cutters would work around it - this is not considered a defect or blemish but under strong magnification it looks like a frosty speck or dust particle. It is slightly eye visible when looking through the stone to the culet when they can sometimes catch the light. Two of the smaller diamonds have some nibbles to the girdle in one area of each but appear complete to the eye.

Typical antique diamonds with some faint natural inclusions, some frosty spots, no dark or glaring carbon spots. The diamonds in the halo surrounding the largest center stone read a bit warm to gray, also typical for antique stones but also because they angle outward so they are not set face up. This causes them to reflect the light differently since the diamonds are viewed from the side, which is how the piece was made. One of the outside diamonds is set a little tilted / listing one way but is very secure in the chunky prongs so it is held firmly. One of the other outside diamonds has one worn prong that has pulled back but again the stone is held securely.

There are no dark spots to the gold, it was just difficult to photograph because it reflects its surroundings. 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 for machine cut stones.) It is difficult to judge antique stones against modern day diamonds with their grading system evaluating their mathematically perfected proportions using methods and standards that didn’t exist for hand cut old cut diamonds. No two old cuts are the same as they were crafted in times lacking those 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. (Although it is also worth noting that many antique collectors prefer and seek out antique diamonds with warmer hues.)

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 stated: “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 their individual beauty or sparkle which are based more on their individual character and uniqueness that each one potentially offers.”
Just an interesting comparison of antique vs. modern diamonds. : ). I always study each diamond in detail under strong magnification so I describe everything that I see, which can be compared against the 4 C's scale if desired.
