Pearl Buying Guide

There are five key factors that determine the quality of a pearl:


‘Lustre’ refers to the shine of a pearl. A pearl with a good lustre is often described as looking as though it is ‘glowing from within’, whereas a pearl with poor lustre will look somewhat flat and dull. When examining pearls, try and look at them in a natural light to see how well they reflect the light: the sharper the reflection, the better the lustre.


The colour of a pearl is dependent on the type of pearl and where in the world it originates. Rarer colours will be more expensive.


Just like with diamonds, the value of the pearl is not wholly determined by the size but rather their rarity, but as a general rule the larger the pearl the higher the price tends to be.


There are three main shapes of pearls: round, drop and baroque. Perfectly round pearls are the most desirable and therefore more expensive.


Just like other gemstones, some imperfections are to be expected. By gently rolling the pearls on a flat surface, you will be able to see any imperfections (they will show as spotting/lines or circles). These are inevitable, but the degree of imperfection or spotting will be dependent on the price. It is not unreasonable to expect medium and smaller Freshwater pearls to be very clean, but, as the size of the pearl increases you should be more tolerant of light spotting.

Pearl Care

The golden rule

Pearl jewellery should be the last thing you put on in the morning and the first thing you take off at night. Cosmetics, hair products and perfume can all cause damage to pearls, so following this rule will help you preserve your pearls’ lustre.


We recommend storing pearls separately from other jewellery. Pearls are softer than other gemstones and can be easily scratched if it comes in to contact with other jewellery. Segmented jewellery boxes and  leather pouches are perfect ways to keep your pearls separate from your other jewels.


It is recommended that you have strung pearl jewellery, such as bracelets and necklaces, restrung every 1-4 years, depending on how often the piece is worn. Keep an eye on the string; if there are signs of  stretching, discolouration  or fraying, have the item restrung as soon as possible to avoid the string breaking. We offer a restringing service in our London head office.

To arrange to have your pearls restrung you can simply take them to our Yoko London Sloane Street store or contact our customer service team to organise the service.


The best way to keep pearls looking radiant is to wipe them gently with a clean, soft cloth when necessary. This will remove any surface dirt, keeping the pearls’ lustre visible. It is important to  remember that pearls need to be treated differently to other gemstones: they should not be submerged in water, or come in to contact with any soap or detergent: this will do more harm than good.
