(… you can also find the answer here http://www.superidealdiamonds.co.uk/blog/where-to-buy-diamond-jewellery/)
The supposition here is that you either live in London, or you are visiting the city; and that you are in need of buying some sorts of diamond items (perhaps a diamond ring, a diamond necklace or something of the ilk). The need for diamond identified, the next step would naturally be to find the London diamonds stores from where you can then proceed to purchase the items you so want. Of course, seeing that diamonds tend to be in the category of ‘prestige’ items, chances are that you will not only be looking for stores dealing with diamonds in and around London, but actually for the very best London diamonds stores from where you can purchase the items you are looking to buy.
There are a number of approaches you can employ to finding the best London diamonds stores.
One approach is simply taking the London telephone directory (if you can find one), going to the section on jewellers, and then calling up (or better still visiting) some of the firms there, and comparing what they offer in terms of diamonds. Take note, if you opt to go this route in your search for the best London diamonds vendors, that the sample you are likely to get won’t be exhaustive, because although almost all London diamonds traders are sure to be listed on the ‘ordinary’ white pages of the directory, only a few opt to be listed on the ‘yellow’ pages where firms are classified according to their businesses (and which is often considered a premium service, for which they have to pay). Indeed, the top London diamonds vendors, who already have a well established reputations and client bases may not see the need to list on the yellow pages. Yet attempting to go through the white pages, identified the firms that might be dealing with jewellery could be a tall order in terms of the time and effort requirement for such an undertaking.
Another approach you could take to identify the best London diamonds vendors would be to conduct an online search for the same. As it turns out, quite a good number of London diamonds vendors have listed on Google map service, where you are not only told where they are to be found in the relatively extensive city of London, but where you are also shown how to get there by Google maps. Of course, if you want an exhaustive sample, it would help to go beyond the few firms listed on top of the Google search for ‘London diamonds’ and explore other options down the results, as not all firms dealing with diamonds in London are likely to have the resources or inclination to list on Google maps.
Besides these two approaches, you could also decide to go traversing through the streets of downtown London, looking through shop fronts to see if you can spot jewellery shops dealing in diamonds. The thing to keep in mind in this approach, though, is that it is likely to be very time consuming, and seeing that most London diamonds dealers are holed up in tall buildings with no external signs whatsoever that they deal in the diamonds, you could actually end up walking through the length and breadth of certain streets in London, without ever identifying any diamonds vendor.
