For millennia humans have been fascinated by the beauty of rare gems, and they have been used for trade in every civilization throughout history. Gemstones are a definitive confirmation of love, wealth and power across the world.

Some stones were, and are, valuable in parts of the world whilst remaining unknown in others parts.

Unfortunately... there are a number of people selling counterfeits and/or very poor quality gemstones for an obscene amount of money.

Sadly, anyone can pretend to be a jeweller, as there is no regulation for this trade. More than 90% of jewellers are unable to differentiate between a genuine and a synthetic stone. This means unless you can afford to make your purchase from a prestigious jeweller, you are most likely going to be sold a poor quality, or even worse, a fake stone from your high street jeweller.

We at GIGA are sadly often asked to assess the value of a "precious stone" after it has been purchased.

It is always very painful to announce to someone that the stone he/she bought is worthless or counterfeit. Having to tell a newly married couple that their wedding rings are not even worth a quarter of the price they paid, nor the precious gem they believed them to be, is heartbreaking.

Synthetic rubies and sapphires have been on the market since 1902, and it is not at all impossible that jewels bought by your great-grand parents and in the family since, are synthetics...

While most of us would try different cars from different brands and discuss the pros and cons of any vehicle before purchasing them, we do not even think to ask for a certificate when buying a precious gemstone. If your chosen jeweller cannot offer you a certificate for your stone, then it is NOT genuine. EVERY true gemstone comes with a certificate of authenticity.

Here at GIGA we believe your money can buy you amazing stones whatever your budget, and we can source you any stone for a fraction of the price you would pay in any main street jeweller.

We believe the choice in most jewellery stores is very limited. If you do not want to offer the special person in your life a ring worn by thousands, then this website is for you.

Whatever your budget, whatever your style, GIGA will find the certified gemstone and wow factor you're looking for.

Browse our easy to use website and choose your colour, your shape, the size you want, and the precious metal you want and we will do the rest.

Our website  presents some of the best current global creations as a guideline for your dream jewel.

What are you waiting for?

Gemstones are expensive. Some very expensive. How will you prove its value if it's stolen from you? How can you pass it on to the next generation without a proven value? This is where you need a certificate, for your insurance company or the legal authorities in your country.
