RING SIZES

HOW TO DEFINE A RING SIZE?


1. Measure the diameter of any other ring that fits a given finger. Read out the ring size that matches the diameter.

2. Measure a finger’s circumference. Read out the size matching the circumference.

Please remember that ring sizes are measured up to 1/10 of millimeter. So the difference between two adjacent sizes might be so small that insignificant and be in the measurement – ballpark.

4C - CARACTERÍSTICAS DE LOS DIAMANTES

EL PESO - CARAT

El peso del diamante se da en quilates (carats). Un quilate equivale a 0,2 gramos. El quilate es una unidad que se divide en 100 puntos, así que, 10 puntos de diamante tendrá un peso de 1/10 quilates, denotado generalmente como 0,10 ct


LA CLARIDAD - CLARITY

Todos los diamantes tienen huellas de siglos de desarrollo. Las inclusiones microscópicas, también llamadas "inclusiones" son una característica integral de las piedras preciosas. La escala refleja la pureza del tamaño, el número y la ubicación de las impurezas en la piedra visible bajo 10 veces de aumento. Los mejores y más excepcionales diamantes también se definen limpios bajo el microscopio. Sin embargo, las piedras en que las inclusiones no son visibles a simple vista también se consideran muy valiosas.


EL COLOR - COLOUR

La mayoría de los diamantes tienen un color delicado, amarillento o de tono marrón. El color se determina por la escala específica utilizando una serie de piedras comparativas. Cuanto más blanco sea el diamante, mayor será su valor. Una excepción puede ser una piedra de colores muy intensos: rosa, azul, amarillo etc. El término ¨color de fantasía¨, se utiliza para las piedras cuyo color es natural, no alcanzado por la tecnología de colorantes artificiales.


El CORTE - CUT

El brillante es un diamante de corte redondo. Los diamantes de otros cortes son definidos de acuerdo con su forma como el diamante de corte esmeralda, oval, marquesa, pera, corazón, princesa. La calidad del corte del diamante es crucial para su brillantez. Debería sacar de la piedra los mejores valores estéticos. El diamante de corte completo se compone de 58 facetas (56 facetas, tablas y culet). El corte de baja calidad puede depreciar el valor de una piedra incluso más de un 50%. La evaluación del corte es la parte más crucial en el proceso de evaluación de diamantes.

ZAFIRO, RUBÍ, ESMERALDA...

EL ZAFIRO

El zafiro es una variedad de corindón, la piedra natural más dura después del diamante. Por lo general, es azul pero hay piedras de todos los colores excepto el rojo. El color azul viene del hierro y del titanio. En algunas variedades de zafiro aparece el fenómeno de asterismo, causado por la existencia de pequeñas impurezas. Los zafiros más preciosos son de color azul y vienen de Cachemira, Birmania y Tailandia. Las piedras de Sri Lanka son más brillantes y las de Australia son más oscuras, a menudo verdosas. En el caso de piedras oscuras, para enfatizar su transparencia, se aplican los cortes planos.


EL RUBÍ

Los rubíes son una forma de corindón. El color de los rubíes puede ser de rojo brillante hasta casi rojo púrpura. Su color rojo proviene del cromo. Igual que los zafiros, estas piedras preciosas tienen asterismo. Los rubíes más preciosos son de color rojo con una sombra de color azul. Este color es característico de los rubíes procedentes de Birmania. Los rubíes siempre han sido muy valorados. Las piedras preciosas de gran tamaño pueden ser mucho más caras que los diamantes. Los rubíes se encuentran en Birmania, Sri Lanka, Tailandia, Tanzania y Afganistán.


LA ESMERALDA

Emerald is a green, the most valuable type of beryl. Emeralds, as well as diamonds, sapphires and rubies are one of the most durable materials known to mankind. It’s mostly light to dark green, sometimes grass green. Its colour comes from admixture of chromium and vanadium. Value of emeralds is based on their beautiful colour and transparency. The most expensive emeralds are dark green, with no cracks or cloudiness. Large, unblemished stones can be more expensive than diamonds. Until the 19th century global market was dominated by Colombian emeralds. Their deposits were later discovered in the Urals, US, Austria, South Africa, India and Zimbabwe.

GOLD INFO...

GOLD JEWELLERY

The oldest gold jewellery is about 6000 years old. Our jewellery will be equally old in 6000 years’ time! Goldsmithing flourished in Europe in the 16th and 17th century when jewellery in similar style was produced. Our design is unique and unrepeatable.


WHAT YOU SHOULD KNOW ?

Gold is a relatively soft metal so it’s alloyed with other metals, such as silver, zinc, copper and palladium. They not only make the gold harder, but also change its colour and smooth its surface. Gold’s hallmark indicates to the nearest 0,001 the purity of gold in the alloy. For example hallmark 0,585 means than in 1000 units of alloy’s mass there are 585 units of pure gold. Until early 20th century gold was mostly hallmarked in carats. According to this system, gold hallmarked 0,585 is 14 carat gold and 0,750 equals 18 carats. Pure gold theoretically is 1000/1000; however, as it’s impossible to remove all impurities, the purest gold is 0.999. Gold with this hallmark is considered pure, 24 carat gold.


Gold’s colour doesn’t affect its price and is simply a result of colour enhancing treatment that consists of increasing the amount of other elements in the alloy. For example white gold has more silver in it than palladium and copper. The most popular colours are yellow, white, pink and red.

How to care for jewellery...

RESPECT YOUR JEWELLERY

Authentic gold or silver jewellery, especially one with precious stones, is like a dress from Chanel so treat it with respect.

Gemstones and natural pearls are particularly vulnerable to loss, cracking, chipping, being treaded down or other damages caused by everyday use. You should take off your jewellery when you are doing housework, going to bed or exercising.

You should be careful when wearing fine, delicate chains. They can be damaged or deformed by a slight pull, even during sleep. When you take off your chain remember not to curl it or bend it too tight as it may cause a permanent deformation.


HOW TO CARE FOR YOUR JEWELLERY ?

1. The beauty of jewellery is durable, but also delicate and fragile. You can enjoy the glow of your favourite jewellery for a long time if you follow simple rules. Most jewellery can be damaged by direct contact with water. Water can affect jewellery is different ways; it may lose its shine or discolour. This applies particularly to pearls and mother of pearl as they are exceptionally delicate and sensitive. Getting marcasite jewellery wet can result in stones falling out. You should always remove all your jewellery before bathing or washing up.

2. Detergents in cleaning products and personal care products like hair sprays, deodorants and perfumes can cause discolouration. Jewellery is made either of pure metal or alloy of different metals that can react with various substances. Chemical products can harm natural or organic stones (pearls, ambers) by tarnishing them or causing delamination. Therefore, you should protect your jewellery from a direct contact with such substances by, for example, applying beauty products before putting on your jewellery.

3. Storing jewellery is also very important. Each piece should be wrapped in a soft cloth and sealed in a separate bag. It will help to avoid damage and exposure to dust etc. A good place to store your jewellery is a jewellery box. It is also recommended to have our jewellery professionally cleaned from time to time.

4. The best thing you can do at home is dust your jewellery regularly. It’s best to use special jewellery wipes. You shouldn’t attempt to clean your jewellery using cleaning product or polishes.
