About

Mark is a qualified gemmologist, diamond grader and jewellery valuer. Insurance valuations are promptly performed on the premises. I recommend your jewellery should be regularly re-valued. Many insurance policies require an updated valuation to be done every 2 years in order to fully cover your precious items.All Valuations are backed up on my computer. So if you ever lose your Valuation, or need a current price on a piece that I have valued 2 or more years ago, I have all the information and can send you a new copy by post.

Heading 2

I understand that the loss or theft of a piece of jewellery is a horrible experience, one that I hope I can make a little less stressful for you. At Mark Nathan we specialize in world-wide insurance cover for loss or theft, so you can be assured your precious piece is covered from the moment you step outside our store. And if you need to make a claim, Mark will work directly with your insurance company or assessor to save you time too.
