How It Works

If you go to our GET AN ESTIMATE form and enter the required details we will give you a clear indication of what we can pay you.

Following your request, we will send you a Royal Mail Special Delivery pack. In the pack you will find a pre-paid envelope and a secure pouch to hold your valuables. The pack is insured for up to £500. If your goods are worth more which normally they are, then when you go to the post office please say you wish to pay the extra cost of about £3 on our parcel which will then give you full insurance cover of £2500. You will also be able to track your Royal Mail parcel online.

When your parcel arrives, we will work out the value of your diamond or diamond jewellery. We will phone you as soon as possible to make you an offer, which hopefully you are happy to accept. Once you have accepted our offer, we will ask you for your bank details, and then do a bank transfer.

In the unlikely event of us not purchasing your items, we will return them to you free of charge, fully registered. The pack will be fully covered by us for the maximum insurance value of £2500.

If you need the money urgently, it may be easier if you send your goods without our free diamond pack as this takes 2-3 days. If you send your goods today we will receive them tomorrow and you could have the money in your account within 24 hours. Please send your parcel to HCFD, 48B Hendon Lane, London N3 1TT and make sure you send it by Special Delivery.

If what you are sending in, isn’t a natural diamond but a cubic zirconia, lab-created, moissanite or an enhanced diamond, then we will have to charge you the fully insured Royal Mail fee plus packing which is £15 for returning it back to you and for using the prepaid pack as we don’t buy them. Also, we don’t accept any GIE or AIG certified diamonds. You can’t use our prepaid pack to send any I1-I3 quality diamonds as we do not pay for the postage either way for any diamonds that are I1- I3 quality. You are most welcome to send them yourself with Royal Mail.
