WHAT IS A GOOD PRICE FOR A GEM?

GIGA is not an online jewellery. We are not selling stocks.

We know the market better than anybody else and we know where to find the best gemstones in the world.

We are cutting down intermediate whole seller. Whatever you are looking for we can find it at the best price for you.

Ask us what you are looking for. We will find it for you. If you are interested in buying it, we will have the stone certified by one of the best world laboratory before selling it to you.

If you are willing to have it mounting in a ring, a necklace or earrings, submit us your wishes and our artist jeweller will design and realise the jewel of your dreams

WHY SO MUCH VARIATION IN PRICE?

On the colour page you have notice we put two needles for lowest and highest prices, on little dials. These variations can be quite huge, especially on high-end gems, a variation from 1 to 100 is common.

QUALITY AND SIZE

Rubbies, poor quality and small ones can trade at $2000 per carat, large and top quality ones at $150 000/Ct...

The good, the bad and the ugly

0.5 to 075 Ct

0.75 to 1 Ct

> 2 Ct

Junk Ruby

$2000-$5000/Ct

$5000-$8000/Ct

$70000/Ct

Bluff stone

$2000-$5000/Ct

$5000-$8000/Ct

$70000/Ct

Top Gem

$2000-$5000/Ct

$5000-$8000/Ct

$70000/Ct

Why such a difference? Well... Very small and poor quality stones are unfortunately more frequent than big top quality ones. The rarer a stone the more expensive it becomes.

The temptation to improve a poor quality stone in something nicer is... huge

CUT

The best gemstones are cut by the best gemstones cutters. And the quality of the cut will affect the beauty of your stone. See our explanation on diamonds, in the properties sections

There are no laws or regulations regarding gem appraisals. Many people write appraisals that do not have the experience to arrive at an accurate value.

This is the reason why at GIGA we sell only stones with certificates coming from the most prestigious laboratories in the world.

Tell us what you are looking for and we shall find the best price/quality ratio for you.
