Diamond Gemstones - Affinity Diamonds

Ruby - Red colour corundum - Affinity Diamonds


The red colour of ruby results from a small admixture of chromic oxide. Only red corundum is entitled to be called ruby, all other colours being classified as sapphires. In Sanskrit, the ruby is called ‘Ratnaraj’, means ‘the king of precious stones’.

For thousands of years, the ruby has been considered one of the most valuable gemstones on Earth. It has everything a precious stone should have: magnificent colour, excellent hardness and outstanding brilliance. In addition to that, it is an extremely rare gemstone, especially in its finer qualities. The ruby is considered as an excellent choice for the jewellery. Beyond its incomparably rich red hue, which alone might be enough attraction, the ruby is second only to the diamond for strength and durability.

Blue Sapphire - Affinity Diamonds


Blue is the main colour of the Sapphire whereas this gemstone is also found in colours like green, orange, pink, grey, colourless, black, brown, and purple. Sapphire is the most precious blue gemstone. It is a most desirable gem due to its colour, hardness, durability, and lustre. Top-quality sapphires are extremely rare in all the gemstone mines of the world. Cutting of this gemstone requires great skills and experience and it is the job of the cutter to orientate the raw crystals in such a way that the colour is brought out to its best improvement.

The Sapphire is also considered as an excellent choice for jewellery. In terms of hardness and durability, it is second only to the diamond (and equal to the ruby). It can be worn everyday without the caution needed with more fragile gemstones like the opal or topaz.

Green Emerald - Affinity Diamonds


The name of this remarkable gemstone comes from the Greek word ‘Smaragdos’, meaning ‘Green Stone’. Its beautiful green colour, combined with durability and rarity, makes it one of the most valuable gemstones. Deep green is the most desired colour in Emeralds.

Although Emeralds are notorious for their flaws they have been considered as high esteem gems since ancient times. Flawless stones are very uncommon, and are noted for their great value, sometimes even more than diamonds. Its good hardness protects the stone to a large extent from scratches but it may develop internal cracks if knocked hard or if exposed to extreme temperature.


Pearl - Affinity Diamonds


A pearl is an organic gem, produced when certain mollusks, primarily oysters cover a foreign object with beautiful layers of nacre.

A good-sized pearl can take between five to eight years to form, which is usually the entire life of the oyster or mollusk.

There are two types of pearls: natural pearls, formed inside wild oysters, practically impossible to find nowadays, and cultured pearls in which the production of the pearl is artificially induced.

Aquamarine  - Affinity Diamonds


This is a fascinatingly beautiful gemstone found in colours like light blue of the sky to the deep blue of the sea.

The more intense the colour of an aquamarine, the more value is put on it. Aquamarine is one of the most popular and best-known gemstones. There is hardly any other gemstone in modern jewellery design which is refined in such a variety of ways as aquamarine.
