sakurabee :  Platinum and gold have different properties. Gold is harder and more brittle. Platinum is denser and more squishy. Gold wants to be shiny, platinum does not. What matters is HOW the stones are set and the workmanship.  The same design made by Tiffany vs. Costco will be dramatically different in its workmanship and long-term durability. 

In all ways of setting a stone, having the stones with a channel or bezel is the most protective. It keeps the stones from getting impacted from the sides. This is the direction of hits that very commonly damage diamond girdles. 

But, the kinds of settings you are asking about are ones where the sides of the stones are open and exposed. These need to be at least 1.8 mm wide (bare minimum) or the metal will flex too much. If the diamonds will stick out beyond the prongs, then you can’t wear the ring against another ring. The diamonds will eat the metal. 

  • A U prong is a kind of shared prong. One prong is shared between adjacent stones. They vary in how much metal is in contact with the diamonds, but tend to have less metal than a 4-prong setting.
  • 4-prong. These are fine. 
  • Pave. For pave, platinum is superior to gold. The metal will tend to deform when under stress and is more likely to keep holding on to your stone. The current trend of thin pave bands are not ideal for longeviety. 

Full eternity cautions:

  • ~unless they have a gap, they can’t be re-sized. Even with a gap, it is tricky.
  • ~the diamonds under the hand will get banged up. Since that location varies, you will spread out the abuse, but they can have longevity issues if not in a channel. 
  • ~the diamonds along the sides (between the fingers) can be pretty uncomfortable unless they are small or you have lots of room between your fingers

I have  a yellow gold 18k and channel set 2.5mm with diamonds and it is perfect, no problems at all, with prongs the risk is that you will knock stones out which happend to me once 😐

My e-ring is a 10k rose gold half eternity. Most articles I’ve read say that rose gold is the most durable of all the gold types. Ive had my ring for over a year and its still in perfect condition. Im not sure what my style of prong is called but Ive never had a lose or missing stone, so its holding up just fine.

Mine is a shared prong setting currently “under construction” and I’m having it made in Platinum, as suggested by my jeweler. The ring sort of has a bezel around the girdle of the stones to protect them but without compromising the “shared prong” look.

Here are some pics (obviously not of the final product), prongs are still going to be shaved down, rounded, etc, and at the end the picture I had as inspiration for the ring. 


ETA: regarding the stones scratching the metal off of other rings, I suggest you use a spacer band, that’s what I’m doing 🙂
