Description:
This man’s ring is to be based on the “ring of Barahir” which is described in J.R.R. Tolkien’s “The Silmarillion”, as well as much later in the Lord of the Rings. There are commercial designs of the ring of Barahir, but they are inaccurate- over jeweled, or over coarse and inelegant. The ring is described thus: “An ornate silver ring”; elsewhere - "this ring was like to twin serpents, whose eyes were emeralds, and their heads met beneath a crown of golden flowers, that the one upheld and the other devoured” and again elsewhere in verse;
"Proud are the words, and all there turned
to see the jewels green that burned
in Beren’s ring. These Gnomes had set
as eyes of serpents twined that met
beneath a golden crown of flowers,
that one upholds and one devours:
the badge that Finrod made of yore
and Felagund his son now bore.”
I would like to use silver or white gold as the main material. Yellow gold for the crown of flowers. Tiny emeralds for the snake’s eyes. My ring size is 10.5.
Anyway, there is the basis of what I am looking for. Oh, and not macho man snakes; snakes that are kind of elegant. Elven snakes if that makes any sense at all.
I've included a rudimentary sketch of my ideas for the relation of the two snakes, as well as a few images of textures like belly scales, and other ideas for the relationship of the snakes. I don't want the ring to be too bulbous or stand too proud, I just lack artistic skill - the ring has to be fairly practical. I'd like the ring to have scale detailing all the way around the band. The crown of flowers can and should be quite flowy and soft - emphasis on the flowers, like a wreath of flowers, rather than the crown.
Keep in mind that this ring is symbolic and a reminder of the dual nature of humanity - at our best, we are noble - but at our worst, we are consuming monsters.
Wants:
Esthetics, understanding of subject material, creativity, detail, functionality, sensuality.
Don't Wants:
No big catches, not standing too proud, not too macho/biker,

Thank You sir Karan :)

Here again is the description in it&;s simplest form from my original post "this ring was like to twin serpents, whose eyes were emeralds, and their heads met beneath a crown of golden flowers, that the one upheld and the other devoured”
The only gems are to be the serpent&;s eyes. There is a crown or wreath of flowers (gold) which rests on the head of one snake, and is in the mouth of the other.
I&;ve attached two images of such flower crown/wreaths for reference. I&;m starting to like what I am seeing!
Remember that the ring will be made of sterling silver so recessed bits will tarnish and become shading, which will make the higher aspects really pop.

Yes you can use solidworks.
can i use solidworks?
I&;ve added SnakeRingSketch1 for the basics of the ring shape, it does not include the wreath of flowers yet, I will include more sketches as I get them (working with a sketch artist).

So, stylexdesign, a 10.5 ring has a diameter of 20.2mm and a circumference of 63.5mm around the inside.
What is the diameter of the ring
The crown of flowers in yellow gold.
The material will be silver or white gold. It is to be an actual ring.
What is the ring material to be? This will help determine surface finish, and appearance. Are we to assume to make it as realistic as a movie prop?

---
## Materials and Dimensions
### Ring Base Material
- Primary Option: Solid 18K Gold (75% gold alloyed for durability)
- Alternate Option: 18K Gold-Plated Sterling Silver (92.5% silver alloyed with copper)
- Finish: High-polish finish; optional Rhodium plating (for silver variant)
### Protective Encapsulation
- Electronics encapsulated using clear resin or silicone to ensure waterproofing and shock resistance.
## Ring Dimensions
### External Ring Dimensions
- Top Width (Visible Area): 9 mm
- Bottom Width (Tapered Area): 5 mm
- Thickness: 3.5 mm (uniform thickness throughout)
- Internal Diameter: US Size 7 (~17.3 mm internal diameter)
### Internal Cavity Dimensions
- Length: 20 mm (along circumference)
- Width: 7 mm
- Height (Thickness): 3.5 mm
---
### ✅ Ring Circumference & Width Tapering Analysis
- Total Ring Circumference: 54 mm
- Internal Cavity Length: 20 mm (this portion has a constant internal width of 7 mm and external width of 9 mm)
- Remaining Circumference (for tapering): 54mm - 20mm = 34mm
### ✅ Width Decrement Calculation
- Top Width (at cavity area): 9 mm
- Bottom Width (opposite side): 5 mm
- Total width reduction: 9mm - 5mm = 4mm
- Width decrement per mm of circumference: approx 0.118 mm per mm
### ✅ Width Tapering Schedule (from top to bottom)
Here's how the ring's external width gradually tapers from the top (9 mm) to the bottom (5 mm) over the remaining 34 mm of circumference:
| Distance from Top (mm) | External Width (mm) |
|------------------------|---------------------|
| 0 | 9.00 |
| 1 | 8.88 |
| 2 | 8.76 |
| 3 | 8.65 |
| 4 | 8.53 |
| 5 | 8.41 |
| 6 | 8.29 |
| 7 | 8.18 |
| 8 | 8.06 |
| 9 | 7.94 |
| ... | ... |
| 17 | ~7.00 |
| ... | ... |
| 34 | ~5.00 |
This gradual reduction ensures a smooth, elegant tapering without abrupt changes, maintaining luxurious aesthetics and wearer comfort.
### ✅ Clarification on Internal Cavity Width
The internal cavity (20 mm length) is located at the top section of the ring, where external width is consistently around ~9 mm, easily accommodating an internal width of ~7 mm.
As we move away from this cavity area, the external width gradually reduces from ~9 mm down to ~5 mm at the bottom, where no cavity exists—only solid metal for structural integrity and comfort.

## Compatibility Verification:
All primary components clearly fit within the internal cavity dimensions of the ring base:
- The largest component width is ≤7mm, matching cavity width.
- Sensors and battery stacked vertically within cavity height of ≤4mm.
- Gemstone plates securely fit into top recessed cavity matching their exact dimensions.

---
## Sealing Mechanism & Heat Management:
The internal cavity will be permanently hermetically sealed using laser welding or adhesive bonding to ensure waterproofing and durability without patent infringement risks associated with open designs.
Heat management is feasible due to ultra-low power consumption of all embedded components (~10 mA current draw), eliminating the need for ventilation openings.
---
## Data Transmission Process
All passive sensors collect environmental data internally within the sealed cavity. Data travels through conductive traces on the flexible PCB to the Bluetooth module (Nordic nRF52840 BLE Module), which transmits this data wirelessly to the user's smartphone via Bluetooth Low Energy (BLE). A companion app receives this data and provides symbolic wellness insights correlated with the currently selected gemstone.
---
## Sealing Mechanism & Heat Management
The internal cavity containing all electronic components will be permanently hermetically sealed using laser welding or high-strength adhesive bonding to prevent moisture ingress and ensure durability.
Heat management is feasible due to ultra-low power consumption of all embedded components:
- Passive sensors generate negligible heat.
- The Bluetooth module produces minimal heat during active transmission (~10 mA current draw).
Ventilation or openings are unnecessary; introducing openings may compromise durability and potentially infringe existing patents related to sealed wearable technology.
