How much is my diamond worth?

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: what is the diamond carat weight  - COLOUR: does the diamond look brilliant white/clear, or grey/yellow

CLARITY: does the diamond have ‘inclusions’  - CUT: how well does a diamond reflect light?


Once these four factors are known, we can determine how much your diamond is worth. Read more about

the diamond grades used by the diamond trade to evaluate a diamond here


What do you mean by 'consumer recycled' diamonds?

A 'consumer recycled' diamond is one that has been previously set into a ring or piece of jewellery....more

Why are your diamonds so cheap compared to others?

We prefer to say ' our diamonds offer great value for money'! - because we deal in 'consumer-recycled' diamond rings,they're classed as 'second-hand' so we can sell them cheaper. We completely refurbish and guarantee every diamond - they're as good as new - but a fraction of the price!  Why? - because the original overhead costs, retailer profit and vat have been written off - you're buying a guaranteed, certified diamond without the expensive add-ons


Do you charge Buyer Commission?

No, we don't - the price you see is the price you pay - simple!


How do you assess & verify diamonds offered for sale?

Every diamond we sell has been assessed, tested and verified using several Internationally recognised specialised diamond testing machines in our in-house laboratory. We also use the services of several independant diamond grading laboratories such as Anchorcert in UK, and GIA in America


How quickly do I get paid?

If you accept our cash offer to purchase your diamond, we will proceed to pay you immediately by whichever method you choose – cheque, inter-bank transfer, or cash.

If you opt for our diamond consignment service, payment will occur when a sale of your diamond is completed.


Is my diamond safe with you on consignment?

Yes – your diamond is clearly marked/tagged with a unique number and is stored in our banker’s grade safes under high security cctv. All items are fully insured.


How long will my diamond take to sell?

We expect 80% of diamonds to sell well before a 120-day period ends. Those that don’t sell in the first 120-day period  are entered into a further 120-day sales period.

Remember, a good quality diamond at a competetive price will sell average quality diamond at a high price will take longer to sell.

Our diamond experts will offer you their best opinion on how to price your diamond.
