Well, different stones have different behaviors. Some of what they say could be true. I have a moissanite ering and a lot of places won’t touch it because they don’t know how to work with it. They can destroy it if they don’t know what they are doing.
Maybe plat has to be heated to a higher temp then white gold and sapphire can’t take the temp?

I have white gold prongs on a yellow gold ring, and after some time (I’ve been wearing mine for about 2.5 years now), you can definitely see that the tops of the prongs most prone to being hit or rubbed on stuff are yellow now.  The prongs that arent exposed to contact with anything are still white.  This is just how white gold will behave since there is no true white gold, it will get worn down to yellow and need replating.  Does this sound like what is happening?  Are the brown spots just the yellow gold shining through?

@MsPandabear: They may have never worked with sapphire before. If I were you, I would take it to another place and see what they say.

@MsPandabear: ooh, that is definitely very strange then.  I’d take it somewhere else to see what they say… that does not sound normal at all.

@MsPandabear: It’s just about as hard as a diamond. 9.25. It’s actually tougher than a diamond because it has no natural fractures that can crack if the stone is subjected to an impact of some kind.

i know that a lot of the time sapphires are heated to make the color deeper/brighter…if you have a natural sapphire that has NOT been heat-treated it’s very true that heat could “discolor” the stone.  you’d know if your sapphire hasn’t been heat-treated though, it would come with a certificate and cost you a heck of a lot more in general.  most sapphires are heat-treated, and i don’t think a heat-treated sapphire would discolor from the soldering process unless it’s REALLY hot.

definitely get a second opinion.

ETA: ok, after doing some quick wiki research, it seems the melting point of platinum is around 1760*C, and sapphire heat treatments (in air, not water or chemicals, so a much lower heat-transfer rate than direct contact with molten metal) occur in the 500-1800*C range…so it seems like discoloration could be a very real danger still, even if it was treated at the highest temperature, and especially if the jeweler doesn’t know what he’s doing.  it sounds like your initial jeweler doesn’t know a lot about sapphires, and realized after the fact that it’s not something he felt comfortable doing himself.  definitely get a second opinion from a jeweler well-versed in gemstones other than diamonds.  i’m seeing tons of sapphire/platinum rings even just on amazon, so i’m sure it’s possible to get what you want with the right jeweler.

@Miss Tattoo:Platinum has to be heated to much higher temp than gold and is more brittle, less pliable, but still strong. Sapphires can and do change color with heat. You can try a different jeweler. They aren’t lying, they’re just not skilled enough (or not risk taker-y enough) to do it. It could be a real issue. It would take a very careful and skilled (read: expensive) jeweler to get this job done.
