How To Choose Your Coloured Gemstone

Stunning, Vibrant, Beautiful

Choosing Your Perfect Coloured Gemstone

Coloured gemstones come in all shapes and sizes, and there is sure to be one to suit your taste, style and budget.

Unlike diamonds, precious coloured gemstones do not have a formal grading system.

But what is not in any doubt is the quality of a coloured gemstone has the same impact on your finished jewellery as a diamond does.

Gemstone Clarity

The imperfections and ‘inclusions’ with-in the gemstones are perhaps a little less significant than in a diamond as their colour disguises minor flaws, but they should still not be large enough to be seen and ruin the beauty of the stone.

Just like in a diamond the cut of the gemstone is essential, in general terms, the more precise the cut of each of the facets of the stone, the brighter the stone will appear.

The proportions of a coloured gemstone have a more permissible variant than diamonds, but the shallower the cut of the stone the less vibrant the colour will be.

Gemstone Colour

Gemstone found with weak colour will be cut thicker to compensate for this, the downside is the extra depth of the stone might impact on the design of the jewellery piece.

An inferior cut gemstone may lead to an ungainly pale ‘colour window’ viewed through the stone.

The back of the gemstone known as the ‘pavilion may sometime be found off centre which again can have an impact in the jewellery setting and produce an uneven colour distribution which if you see when you are looking at a gemstone is something you should avoid.

Another sign for this unsightly version of stone is a visible feature of dark and light bands of colour. Light stone will in general lack impact, and overly dark stone will not exhibit the richness of colour. However, personal preferences in colour tone and intensity also need to be taken into account.

Gemstone Value

The gemstone trade, gemstone investors and lovers of coloured gems have established an unwritten preferred combination of tone, intensity vibrancy, and intense colour and it is these stones that command the highest prices.

Setting all this aside when choosing your ideal gemstone your skin tones need to be taken into account as well as the jewellery setting and what is one person’s favourite colour may not be another, that’s is the pure beauty of choosing coloured gemstones over diamonds.

The above guide to colour gemstones applies to most coloured precious stones: Sapphire, Ruby, Emerald, Tanzanite, Aquamarine… There are of course some exception such as pearl and opals which have entirely different parameters.

My new fiancee and I are delighted with the ring David created. Having sent out several enquiries he was the first person to get back to me, and was clear and up-front on all aspects of the process from the outset. Despite having undoubtedly worked on far costlier projects, at no point did I feel that our job was any less important to him. The final piece is beautiful and even better than we expected - thank you David for your time and expertise!

David continues to exceed expectations with respect to being a truly personal jeweller. Having made an outstanding engagement ring for my wife over 10 years ago, he's made matching eternity rings after 5 and 10 years that have seamlessly matched. Timeless designs, effortless customer experience. Thanks David!

My experience designing an engagement ring with David was excellent. He was flexible and patient as we worked towards a bespoke, custom and alternative engagement ring.

The wax printing of each iteration helps with the design phase and the final product was fantastic.

My partner was over the moon with the necklace I gave her for her birthday, which was designed and made by David. He came to my office twice at my convenience, talked me through the process, was reasonable in pricing and extremely friendly. When I requested a last minute change, David obliged, went back and made the necklace exactly to my request. A great experience and fabulous outcome. I will be using David's services again!
