Fill in all the details below, to get an instant cash price for your diamond

   
Diamond weight (Ct) Please enter only the weight of individual diamonds, not a total weight of assorted diamonds. A diamond's weight is measured in what is known as a 'carat', which is a small unit of measurement equal to 200 milligrams. Carat is not a measure of a diamond's size, since cutting a diamond to different proportions can affect its weight.
Click to select shape    
Diamond Shape Diamonds come in all shapes imaginable and diamond cutters are still experimenting to discover more. A diamond cutter's skill will produce a diamond of the greatest size with the fewest flaws and the most brilliance from the rough stone.
   
Diamond Colour Diamonds graded D - F are the rarest and most expensive, whereas the ones graded G - J are seemingly colourless to the untrained eye. Diamonds with grades K - Z are more noticebly yellower.
   
Diamond Clarity A diamond's clarity is a measurement of the amount of blemishes (external flaws) or inclusions (internal flaws) a diamond contains.
Diamond Certification A diamond certificate is a report created by a team of gemologists, also known as a diamond grading report, diamond dossier or a diamond quality document.
Diamond Certificate Number Please enter the certificate number for your diamond if you know it as this will help us to locate its details.
Currency Choose the currency in which you would like the price to be calculated.

How to sell a diamond …

Sell diamonds to HOW Cash for Diamonds in the knowledge that this is the best place to sell your diamonds. We are a diamond ring buyer specialist so if you are looking for the best place to sell a diamond ring for instant cash, then HOW Cash for Diamonds can advise you and guide you through the sale process.

Sell diamonds : use our diamond price calculator.

Our customers ask 'How much can I get for my diamond ring?' or 'How to sell a diamond or jewellery for the most money?' or 'Where can I get the best price for my diamond ring or diamond jewellery?'. HOW Cash for Diamonds prices are market leading and our initial evaluations are as accurate as possible.

We buy diamonds of any size, shape or grade, even broken or in poor condition. You can sell diamond rings from the most expensive designs to the smallest diamond jewellery item.

How much can I get for my diamond?

Obviously this is the single most important question when you are considering selling a piece of diamond jewellery. The value of a diamond is primarily determined by its 4C's:

CARAT: how much does the diamond weigh?
COLOUR: does the diamond look yellow?
CLARITY: can you see any 'stuff' in the diamond?
CUT: how well does a diamond reflect light?

Once these four factors are known, we can determine how much your diamond is worth. To make this process as quick as possible we have come up with the Sell Diamond Price Calculator that will allow us to quickly place a value on your diamond.

Sell diamonds for cash

Cash For Diamonds

Sell diamonds for cash: how it works.

We will buy any diamonds, from £50 to £100,000, and settle the transaction direct into your account the same day. We pride ourselves by inviting any of our customers to our premises from 10am - 4pm Monday to Friday, except bank holidays. We will evaluate the diamond in front of you, in our diamond office, and are able to pay for your diamond, straight into your bank account via BACS transfer whilst you wait.

Alternatively, cash can be organised on request (minus a small handling charge). 

Selling Diamonds
If you are unable to visit our premises, we have probably the World's First Online Diamond Evaluator. Simply enter all the details about your diamond, and once our Diamond Calculator has evaluated a price for your diamond, keep one copy for yourself, and put a copy of this with the goods that you are sending to us by Royal Mail Insured Delivery.

If you live outside the UK, read our FAQs

To calculate the price of each individual diamond all you have to do is –

1. Enter the weight

2. The shape 

3. The Diamond colour

4. The Diamond clarity and

5. State which certificate, if you know it

Then just press 'Calculate Price', and you will get an instant guideline to what we will be able to pay you. The price will be confirmed once you post the goods to us by Insured Special Delivery (Special Delivery maximum insurance £2,500)

With Royal Mail's online tracking system, you will be able to track your parcel at any time. In the last 4 years, we probably had delivered by Royal Mail nearly 20,000 parcels, and one has never gone missing!!
