Hi, I'm new and I don't really know anything about gemstones! I love colored gems (tanzanite is my favorite) and I buy jewelry that I really love and that's sparkly. The most expensive piece of jewelry I own is a tanzanite ring from the Bradford Exchange ($120) and I'm 99% the booklet said it was genuine tanzanite. However, looking at the ring on their website the word "genuine" is never used so I'm not entirely sure what I have lol. It's very pretty though and I love it! I've never bought an expensive piece of jewelry for myself (the ring was a gift) so I'm unsure of what to look for exactly. I've read about what I'm supposed to look for but it is all a little confusing to me since I'm so new at this. So I do have a question. I fell in love with this blue topaz bracelet from Belk and I'm just wondering if it's worth paying $320 for it (it says it was originally $800 but I'm thinking that's WAY too much for blue topaz and sterling silver) I love the different shades of blue and different sizes of the stones and bracelets are my favorite jewelry pieces
$320 is a huge leap from the $20-$40 Avon bracelets I buy! I do really love the bracelet but I would hate to pay so much for it if it's only worth like $50 or something. Any opinions, advice, and information would be appreciated
