Just because it’s a sapphire doesn’t mean it will be worth much, especially if you don’t know all the treatments on the sapphire (do you?). I’m not sure of the quality of the sapphire, and a tanzanite that size isn’t valuable, but I would think that diamond and at least 14k gold setting (metal?), is worth more than $75, but nowhere near $7500.I have a sapphire ring that was purchased from a jewelry store a couple years ago. It’s a 1.42 ct sapphire set in a micro pave halo setting. I took it in to another jewelry store recently to see how much I could get for the ring. The person doing the evaluation told me the stone was a tanzanite and the entire ring wasn’t worth any more than $75 which is less than 1% of the price initially paid for the ring. Suggestions on next steps? Is it worth getting it appraised by someone else to determine if it is a sapphire or tanzanite?

Unfortunately, if you bought it from a jewelry store, there’s an enormous markup.
Err yes, what was the basis for that evaluation? Did they just eyeball it and pronounce it was tanzanite? Should be some pretty simple tests you can get done to verify. Unless you have a pre-existing relarionship with the jeweler, I would be wary of anyone offering to buy the stone off you and simulteneously telling you it is not worth very much.
I bleieve tanzanite often shows different colours when viewed along different axes. Does it shift from blue to purple depending on what angle you view the stone from?
Edit I pulled this at random, and only read the first two paragraphs but it talks about the different refractive indicies along different planes of the crystal structure

Did they know you were thinking of selling it? Sounds like they just threw out a total lowball number hoping they could get it on the cheap.
Tanzanite and sapphire have fairly different refractive indices, so anyone with a refractometer *shouldn’t* confuse them. Did they just eyeball the identification, or give you any reasoning why they called it as tanzanite?
That’s helpful to know! Thanks for the info.For a random data point, I just weighted a plain 2mm band and computed the melt value at 14k - $65.
I knew going in I wasn’t going to be getting anything near the amount it was purchased for, but I was taken aback that they felt it was $75. The ring is a 14k gold setting
If it’s a tanzanite, it will shatter in an ultrasonic cleaner. Many jewelers have no clue and put anything and everything in an ultrasonic cleaner.I forgot to say -- when you take it elsewhere get the jeweler to advise you on whether it can be put in an ultrasonic cleaning device. I think you have a lot of residue on those daimonds -- if they clean up well the setting will be worth a lot more. Ofcourse this will be highly detrimental if the main stone is heavily treated with some kind of infilling (unlikely but it is better to ask the jeweler whether they think it is ok before wacking it in the machine).

While a heat only sapphire is worth more than a Tanzanite, that is not a $75 ring.
With a Presidum gem tester you can differentiate between sapphire and Tanzanite (but not lab grown sapphire from natural sapphire but that’s a separate issue).
Did the jeweller test it in any way or just look at it with a Loupe? The colour is Tanzanite like but you never assess a gemstone just on colour.
If you paid $7,500 you unfortunately paid way too much. A sapphire around 1.5 carats is maybe up to $2,500 and a diamond ring mount maybe $1,000. That’s new, selling secondhand you can usually expect half that or less.
If you get an appraisal that confirms the sapphire (or Tanzanite) and give a diamond weight estimate you can sell it yourself on free sites like Loupe Troop or even on eBay (fees will be about 13%) but any jeweller or pawn broker is only going to offer a ridiculous (insulting even) low amount so don’t think about selling to them.
I think the jeweler you spoke to is probably an incompetent one or a liar - or possibly both.
I assume you don’t have the papers from the original purchase showing the details of the ring.
I would recommend contacting the store you bought it from and getting the paperwork. Once you have verified the stones authenticity you can list the ring for a fair selling price. I would not go back to the incompetent jeweler who can’t tell a sapphire from a tanzanite though . That is wild that they would mistake one for the other.
Go to an Independent Appraiser for an appraisal and evaluation of the center Stone and basis for evaluation.I have a sapphire ring that was purchased from a jewelry store a couple years ago.
