The 5th C – Confidence in your Jeweller
As we all know, the 4 Cs in diamond grading are Clarity, Colour, Cut, and Carat weight. However the 5th C is probably just as important. At Diamonds by Design you may be confident that you are dealing with trained gemmologists, valuers and diamond graders.

Nearly 80 per cent of our business comes through referrals.

Recently a new client came into our showroom, recommended by one of our loyal customers. This lady had received misleading advice and was quite confused and disenchanted with the jewellery industry.

She had received ill-defined claims of quality and dramatic variations in price and told us that she needed to have confidence in the dealer. We were able to guarantee this through our one-on-one consultations.

However, do remember that quality comes at a price.

All our diamonds come with certificates from the DCLA an internationally recognized laboratory, grading to International Diamond Council (IDC) rules, established jointly by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA).
