I apologise Wireless and Martinjay but I do not agree. This is why:
Let's say you bought a ring 5 years ago with a Paraiba Tourmaline for £600 (just using rounded up numbers).
Let's say the central gemstone - in this case a Paraiba Tourmaline - bought at that time when there was a lot on the market was sold to you at a very fair price.
You had the ring valued today and the replacement valuation (i.e. for you to buy the same ring at today's prices not it's worth or value) is £5,000.
You try to buy the same thing for £600. You can't. The reason you can't is because there is very little PT on the market and what is, is definitely NOT the quality from 5 years ago (that's assuming you bought well). That's fact and not disputable.
To buy the same size good quality PT now you need to really hunt around and then pay top dollar because it's in short supply. Fine, you can argue that you've paid a premium on a higher valuation and you will have. That's why it's absolutely non-sensical to insure and have valued pieces that you can easily buy today. A valuation via Safeguard is NOT an indication of worth or value (apologies for sounding like a presenter). It is the cost to replace if you lose it and takes into account having the item made from scratch by a jeweller, the gold weight, the accent diamonds, the cost of buying the central stone again.
Safeguard is independent and NOTHING to do with Steve Bennett. Safeguard are affiliated to the Birmingham Assay Office (which isn't hidden in any way) and who are also independent and NOTHING to do with Steve Bennett. He may get favourable rates to hallmark items because of the sheer volume (as other big jewellery importers will). He also knows them well because he's based near to them. Any more than that and it's just conspiracy theory. You may want to give Carla Hicks a call at Safeguard if you want assurances.
If KB sees this thread I hope she chimes in because she has worked in insurance and can confirm the above. In fact, there was thread on it some years ago so if you search you may be able to find it.
Martinjay - A valuation is not about value or worth. It is for insurance purposes only. Not re-sale. There are gemstones such as Alexandrite, unheated/untreated Rubies, Bixbite etc., where IF you have bought a very high grade gemstone, it may become an investment piece. However, for Topaz, Citrine, Amethyst etc., it's worth, typically, a fraction of what you pay because it's available for peanuts so akin to buying a new car and driving it off the forecourt - you immediately lose money. I would NEVER get such a piece valued or insured as it's a total waste of money.
