that's fascinating so anyone buying real diamonds as an 'investment' will potentially lost cash ... it is not gold is it ?
Anyone buying Diamonds at retail prices for 'investment' will likely be in for a shock anyway when they find out that they're offered less than they paid for them years down the line.
The only people that are likely to make any money out of Diamonds are either:
a) Those that can get them at trade prices and sell them on at retail prices.
b) Those with exceptional quality, in-demand, diamonds (ie, flawless or internally flawless).
c) Someone lucky enough to have a huge, larger-than-the-norm, carat weight Diamond of decent quality.
Normal retail grade, included, Diamonds are available en masse - nobody is going to be making big investment profits on those. The same applies for tiny Diamonds sold in clusters rings.
That's exactly why Gemporia presenters say "we can't give investment advice" before giving investment advice in a round-about way. They know that the stones aren't going to go up in value by any significant margin - so they're covering their a**e in case Granny Smith is disappointed in 20 years time when she's offered £400 for the ring she paid £600 for, or, if she's really lucky, offered £600 for the ring she paid £600 for.
Remember Mirabelle, the Gemporia customer that spent thousands buying 'legacy pieces' from them ever since Gemporia started as a business? She passed away and her family had to start a GoFundMe page to pay off her debts. Steve Bennett himself donated £100 to it. If her jewellery had been the 'legacy pieces' she thought she was buying, then the family would have been able to sell her 'investment pieces' to clear her debts. Not only that, but if they truly were 'legacy pieces', instead of Steve Bennett donating £100, you'd have thought he'd have been jumping through hoops to get his hands on Mirabelle's 'legacy pieces' in the knowledge that their value will only increase if they were supposed 'legacy' quality. The fact that he didn't buy them back speaks volumes........
