Authenticity is more important than anything when investing in precious jewellery. You can buy an heirloom gold necklace or a glittering diamond ring and before you make the mistake of losing money, you only have to know how to check its authenticity. Nowadays, when fake products are becoming more and more advanced, it is necessary to be a knowledgeable consumer.
In Dishis Designer Jewellery, we know the significance of trust and transparency as far as fine jewellery is concerned. This will be a guide on how to recognize genuine gold and diamonds so that you can ensure you are buying a good and authentic one.
Why Authenticity Matters More Than You Think
The jewellery market in the world is regrettably full of counterfeits, plated metals that are sold as solid gold and artificial stones that are sold as natural diamonds. To the uninformed buyer, the visual distinction between the real and the fake is almost undetectable at least by the naked eye. Fashion jewellery can not only lose its value in a short time but can also lead to skin reactions, tarnish easily and break the emotional value of the jewellery.
Other than the loss of money, there is the issue of trust. A present that proves to be counterfeit is very intimate. This is the reason why you must arm yourself with a couple of simple tests and knowledge points before you open your pocket-book.
Understanding Gold Hallmarks and Purity Stamps
Checking of hallmarks is the most sure thing to do when determining genuine gold first. True gold jewellery will always be marked with a purity mark by a recognised hallmarking authority. In India, purity grade (e.g. 916 in 22-karat, 750 in 18-karat) and assay centre mark are included with the logo of BIS on the hallmark.
• 916 stamp = 22-karat gold (91.6% pure gold)
• 750 stamp = 18-karat gold (75% pure gold)
• 585 stamp = 14-karat gold (58.5% pure gold)
• 999 stamp = 24-karat gold (99.9% pure, mostly investment bars)
When a piece does not have some hallmark, this is a red flag. Even the old jewellery of good provenance usually bears some kind of assay mark or mark of maker. Always demand to see the stamp with the aid of the loupe or magnifying glass before you buy.
Pro Tip: Plated jewellery can be faked with hallmarks. Hallmark verification should be always accompanied by at least one physical test as a check.
Basic Home Tests to Check Gold Authenticity
To conduct a dependable first-pass test on gold, you do not need to go to a laboratory. A number of simplistic techniques can provide you with a decent clue as to whether a work is authentic or not.
• The Magnet Test:
REAL gold is not magnetic. Hold a strong magnet close to the piece. When attracted, the metal would be iron or nickel with gold plating.
• The Skin Discolouration Test:
Real gold and diamonds will not react with your skin. When the colour of the surface below the jewellery turns either green or black when worn, the underlying metal is probably copper or some other alloy.
• The Acid Test:
Jewellers employ nitric acid kits offered in jewellery supply shops. A drop on a scratching of the metal will melt away the artificial gold but not real gold.
• The Float Test:
Gold is dense. Put the piece into a glass of water, true gold will sink outright, but plated or hollow ones will either rise to the surface or sink slowly.
• Ceramic Scratch Test:
Rub the piece on unglazed ceramic. Gold leaves a streak of gold-colour, and false gold leaves a streak of black.
These tests are good indicators but an ultimate confirmation is always made by a certified jeweller through the use of electronic gold testers or XRF (X-ray fluorescence) machines.
How to Find a Real Diamond
Diamonds have been rated as one of the most faked gems in the world, and the commonest substitutes are cubic zirconia (CZ) moissanite, and white sapphire. Both have their characteristic differences. This is what to look out for.
1. Fog Test:
Breath on the diamond just like you would fog a mirror. A real diamond will heat up and spread heat immediately, and disperse within one or two seconds. A counterfeit stone will remain fogged three or four seconds more due to the fact that it will retain heat.
2. Newspaper Test:
Lay the stone on a segment of printed text, face down. When you are able to read the letters with the help of the stone, the stone is probably not a real diamond. True diamonds are so thick that you do not see through.
3. Under UV Light:
About 30% of real diamonds emit a blue fluorescence under ultraviolet light. Although not every diamond will be blue when exposed to UV, a totally inert stone when exposed to UV may be a possible indicator of a simulant. This test cannot and should not be used on its own but in combination with others.
4. The Loupe Inspection:
Under a magnification (10x loupe) one can see tiny inclusions of most natural diamonds, internal flaws that occurred during the crystallization process. Stones that are perfect and can be seen under a loupe without any inclusions are more inclined to be artificial or man-made.
The 4Cs as an Authenticity Framework
All real diamonds are accompanied with a record of their Cut, Color, Clarity, and Carat weight – the world standard of 4Cs grading. A diamond that lacks a grading certificate of a reputed laboratory like GIA, IGI, or HRD should be handled with caution. Always request certification.
The Role of Certification and Documentation
No matter the quality of your eye, nothing takes the place of a third-party certificate. In buying diamonds, it is always important to seek a gemological certificate in a recognised independent laboratory. In the case of gold, demand a hallmark certificate and invoice with the seller indicating clearly the karat purity and net gold weight.
A legitimate supplier will never be reluctant to give documentation. Actually, they will be ready. The information such as the size, weight, cut grade, color grade and clarity of the stone should be added in certificates. Compare the information on the certificate with what you observe in the stone. A slight difference in carat weight should be a concern.
Be cautious of those sellers who are selling certificates with grading labs that are unknown or obscure. Other dishonest sellers offer in-house certificates which have no independent verification value at all.
Red Flags When Buying from a Jeweller
when buying from a real store there are warning signs that the jewellery may not be what it seems:
• Unusually low prices compared to what others are charging. If it seems too good to be true it probably is
• They do not want to give you details about the hallmark, certificates or written invoices
• They want you to buy right away without time to check
• Stones that look too perfect under a special light. Real diamonds always have some flaws
• Gold jewellery that has a greenish or pinkish colour in bright light which can mean it is plated
• No way to return or exchange. Honest jewellers stand behind their products
Trust your feelings. If something feels strange when you are buying it probably is. Take your time, ask every question and do not let people pressure you.
When to Get a Professional Help
If you got jewellery from someone as a gift or bought it by hand getting a professional appraisal is a good idea. A certified expert or appraisal service will look at the piece with tools and give you a written report on what it is made of, if it is real and how much it is worth.
This is also an idea before ensuring your jewellery as insurance companies often need an independent appraisal. Getting an appraisal from someone who’s not the seller makes sure they are not biased.
It is also worth noting that gold prices and diamond values go up and down. An appraisal done five years ago may not be accurate today. Getting an appraisal every three to five years is a good practice for anyone with valuable jewellery.
Final Word
Knowing how to spot gold and diamonds is not just for experts. It is knowledge that helps every buyer. From reading hallmarks and doing tests at home to understanding the importance of certification and professional appraisals, each step you take brings you closer to making a purchase you can really trust.
The jewellery you wear means something. Celebrating moments showing love and standing as a testament to craftsmanship. At Dishis Designer Jewellery every piece is made with materials, complete transparency and the assurance that what you get is exactly what was promised. Because real jewellery deserves trust. And so do you.
