General care

Over time, fine jewellery can become a treasured family heirloom if it is cared for properly. Dust, pollution and daily wear all conspire to cloud the brilliance of gemstones. The surface of gold, platinum and silver jewellery can become dulled. Timeworn prongs and clasps can result in the loss of a stone or an entire piece of jewellery

Professional cleanings are recommended as often as once a year. We encourage you to bring your TEJORI jewellery back to us for professional servicing. Our staff is knowledgeable and experienced in all aspects of jewellery care, including cleaning gemstones, restringing pearls and repairing clasps and earring backs


Your TEJORI jewel is a precious and refined piece and proper care in its use and handling is required in order to keep its original splendour over time.

Clean the piece of jewellery in lukewarm water and soap with a soft brush, excluding jewels with leather parts, which have to be cleaned with a soft cloth Keep the piece of jewellery in its original case and/or pockets after use. Always place your jewellery on a soft surface. Avoid contact with other jewellery and other metal objects. The friction can deteriorate the jewel’s shine.

Avoid forcing clasps, joints and metal frames. Prevent damage or loss of your jewellery by storing it safely before practising any sport. If your jewellery suffers a shock or hit, the setting of the stones may have to be checked to prevent their loss. Avoid contact with perfume, alcohol, cosmetics, ammonia and chlorine.

Bring jewels to a TEJORI boutique for a periodic check and professional cleaning.



Gold is a precious metal. It has emotional, cultural and financial value and different people across the globe buy gold for different reasons, often influenced by a range of national socio-cultural factors, local market conditions and wider macro-economic drivers. Humans have been decorating themselves with gold since at least 4000 B.C., according to the National Mining Association. From Eastern Europe to the Middle East to the tombs of Egyptian Pharaohs, gold appears throughout the ancient world. A Stone Age woman found buried outside of London wore a strand of gold around her neck; Celts in the third century B.C. wore gold dental implants; a Chinese king who died in 128 B.C. was buried with gold-gilded chariots and thousands of other precious objects. Gold is malleable and shiny, making it a good metalworking material. Chemically speaking, gold is a transition metal. Transition metals are unique, because they can bond with other elements using not just their outermost shell of electrons (the negatively charged particles that whirl around the nucleus), but also the outermost two shells. This happens because the large number of electrons in transition metals interferes with the usual orderly sorting of electrons into shells around the nucleus. All the gold that makes up earrings and cufflinks and electronics components today originated in space: According to a 2011 paper in the journal Nature, a meteor bombardment nearly 4 billion years ago brought 20 billion billion tons of a gold-and-precious-metal-rich space rock to Earth. Tracing gold’s origin back even further takes us into deep space. A 2013 study in The Astrophysical Journal Letters found that all of the gold in the universe was likely birthed during the collisions of dead stars known as neutron stars. Veins of gold mined from the earth are the result of hot fluids flowing through gold-bearing rock, picking up gold and concentrating it in fractures, according to the American Museum of Natural History (AMNH).


What is a karat?

Most gold jewellery isn’t made of pure gold. The amount of gold in a necklace or ring is measured on the karat scale. Pure gold is 24 karats. Bars of gold kept in Fort Knox and elsewhere around the world are considered to be 99.95 percent pure, 24-karat gold. As metals are added to gold during jewellery making, the gold becomes less fine and the number of karats drops. For example, 12 karat gold contains 50 percent gold and 50 percent alloys by weight. The word karat comes from the carob seed. In ancient Asian bazaars, the seeds were used to balance scales that measured the weight of gold.



TEJORI  Guarantee of Quality

 TEJORI has sold diamonds for over 50 years, and we partner with some of the world’s most reputable diamond distribution companies (Antwerp, Mumbai, New York). All TEJORI diamonds are sourced from industry experts whose professional ethics are of the highest standards, so when you buy with us you can be 100% sure that you get a great stone and a good deal, every time.

Before You Buy – The 4 C’s

Before you buy, you will need to know a little more about diamonds so that you can feel that you know what you are spending your money on. You may have heard of the four C’s – Cut, Clarity, Colour and Carat weight. You will be glad to hear that TEJORI take diamond buying one C further. We offer total buyer Confidence by offering internationally laboratory certified diamonds (for half-carat size and over). The four C’s are the criteria jewellers use when grading diamonds, and these are the ones you’ll need to understand to buy the right diamond for you.

  • Carat Weight:

    Carat is the unit of weight by which a diamond is measured. Because large diamonds are found less commonly than small diamonds, the price of a diamond rises exponentially to its size. Most solitaire diamonds are sold by TEJORI are over half a carat, but smaller sizes are available to meet every budget.

    What Carat Weight Should I Choose?

    First you need to determine your budget as this will help you decide what type and size of diamond you can go for. A general rule of thumb when buying a diamond engagement ring is that the spend should be approximately two months’ salary, but this is just a guideline that people use and it is obviously not set in stone (pardon the pun!). Only spend what you can comfortably afford and be honest with your jeweller from the beginning so that the perfect diamond can be found for you.

    Great jewellery is a balance between size, gem quality and setting aesthetics. If there is a preference for larger sized jewellery items, and you are working within a budget, you can still find a larger diamond of excellent quality gem by selecting one which is graded slightly lower in terms of colour and clarity.

    Also remember that slender fingers make small diamonds look bigger, so if the person that is wearing the ring has small fingers, a 1-carat diamond will look proportionately large — and an even larger stone will have a truly knock out appearance.

    Think about what sort of setting will hold the diamond. You’ll have to be sure that the setting you choose is made to fit the carat weight of your diamond. Larger stones need strong settings and four or six prong settings are ideal for solitaire diamonds as they keep them really secure in the I show virtually no colour that is visible to the untrained

  • Colour

    A colourless diamond, like a clear window, allows more light to pass through it than a coloured diamond and colourless diamonds emit more sparkle and fire. The formation process of a diamond ensures that only a few, rare diamonds are truly colourless. Thus the whiter a diamond’s colour, the greater its value. Remember, colour is a result of the composition of the diamond, and it never changes over time so choose your colour wisely as this is most likely going to be one of the most important jewellery purchases that you will ever make. Aim for the best colour that your budget will allow and your stone will shine forever.

    The professional colour scale begins with the highest rating of D for colourless, and travels down the alphabet to grade stones with traces of very faint or light yellowish or brownish colour.

    Which Colour Grade Should I Choose?
    Diamonds graded D through F are naturally the most valuable and desirable because of their rarity. Diamonds of this colour are wonderful, however, diamonds graded G through I show virtually no colour that is visible to the untrained eye. 
  • Clarity

    Because of the incredible journey a diamond takes from its complex crystalline formation to the point at which the rough stone is mined, most diamonds contain some inner flaws or inclusions. The visibility, number, and size of these inclusions determine what is called the clarity of a diamond. Diamonds that are clear create more brilliance, and thus are more highly prized, and have a higher price. Jewellery quality diamonds have a clarity range:


  • Cut

    Cut is probably the most important, and most challenging, of the four Cs to understand. The brilliance of a diamond depends heavily on its cut, so you need to aim for “VG/VG” (Very Good) or better (Excellent) if possible. Good cuts can also offer great value, but your diamond professional can guide you on this at the time of purchase.

What is a Diamond Laboratory Certificate?

A diamond laboratory certificate, which is sometimes called a grading report, is a complete evaluation of your diamond that has been performed by a qualified professional with the help of special Gemological instruments. Each stone bears its own recognisable, individual characteristics, which is listed on the certificate, so this certificate will show you exactly what you have purchased. These certificates are also required for insurance purposes as they indicate an accurate replacement value in the event of loss or theft.

Any pearl formed inside a living oyster or  mussel.


Pearls formed by accidental in a living oyster without any outside intervention from man if a tiny foreign particle gets lodged inside, the oyster starts to cover with an iridescent and lustrous substance known as nacre. Gradually over the years a beautiful pearl is born.


Pearls formed by the assistance of man. Man inserts the irritant inside the oyster, which induces it to form a pearl.
