WHO WE ARE
The diamond dream and the consumers’ desire for diamonds is the core of our business. Unlike any other mining products, diamond value comes from the luxury market of jewelry. The Diamond dream is very much alive and demand for rare diamonds continue to rise. Diamonds represent; a universal symbol of love and commitment, an elegant symbol of success, timelessness and store of value. We at House of Gems are devoted to these beliefs. House of Gems is a second-generation diamond house founded by Rajesh Sheth in 1986.Over the last decade; the company has acquired and manufactured some on the most prestigious diamonds in the world. We specialize in investment grade diamonds. Our goal is to provide customers with high-quality, perfectly cut diamonds that will appreciate over time. Having a global presence allows us to obtain the finest gems around the world. The company’s high standard in diamond selection has proven diamonds to not only be a beautiful luxury, but an appreciating asset as well. Our firm is committed to maintaining the highest ethical standards and business practices. Customer satisfaction is very important to us; we aim to develop a lifelong relationship based on mutual respect and fairness.
Everyone knows that a natural fancy colour diamond is extremely rare, but do you know how rare it is? For diamond mining, over 250 tons of rock needs to be blasted, crushed, processed and x-rayed to yield just a 1-carat diamond. More than 120 million carats are mined every year and less than a quarter of them will end up in jewellery based on their gem quality. Out of that amount, only one in a few hundreds of thousands possesses enough colours to be classified as a "natural fancy colour diamond".
The positioning of fancy yellows is unique — they are the most popular natural fancy colour diamonds while relatively speaking of course, they are the most common ones, It is estimated that around 60% of all natural coloured diamonds belong to the fancy yellow category. As a "common" colour diamond and a "rare" gem, many customers regard yellow diamonds as their favourite stones. Let’s explore into these irresistible diamonds.
The presence of nitrogen causes yellow colour in diamonds. Molecules of the gas are absorbed while the diamond crystal forms, being trapped in the spaces between the carbon atoms. These molecules themselves absorb certain wavelengths of the white light (Daylight) as it travel through the diamond crystal and effectively converts the diamond into a colour filter allowing us to see only the yellow colour. As in all cases if coloured gemstones are viewed in artificial light their colour will alter according to the wavelengths
Profile pink diamonds have led several auctions in recent years. The 24.78 carat "Graff Pink" diamond sold at Sotheby's for $46 million on November 16, 2010. In May 2011 Sotheby's sold another large pink diamond for $10.84 million, a 10.99 carat fancy intense pink. While natural pink diamonds are costly and rare, pink diamonds of varying carat weights, hues and saturation’s are available.
The colour of pink diamonds is generally thought to be caused by coloured graining, which results from structural irregularities in combination with an impurity. Until recently, the cause of pink colouring in a diamond remained somewhat of a scientific mystery. What is known is that unlike other coloured diamonds (greens, blues, yellows, etc.), the colour pink is not due to foreign trace elements trapped inside the diamond’s structure. Some scientist’s point to an atomic-level lattice defect that selectively absorbs light producing a pink hue, but the actual cause has yet to be revealed. A pink diamond, like other coloured diamonds, comes in several shades and tones. From a faint pink to the extremely rare fancy vivid pink and purplish pink. The lighter the pink tone, the less expensive the diamond. Heavily saturated pure pinks and purplish pinks are considered collector’s items, with prices reflecting their rarity and desirability. Most pink diamonds originate in South Africa and in Australia.
Studies show that blue is the most unseen colour in nature and the combination of the most valuable natural crystal, fortunate enough to encounter boron particles during its enigmatic birth (boron is the element which causes the blue colour in a diamond) creates with no doubt the most desirable coloured gem throughout history, auction sales and today's market.
Any diamond with a green hue means it has spent a few million years being bombarded with a radioactive source.The reason that a true green diamond is so valuable is that radiation does not usually affect the entire gem, meaning that the stone may be green only in patches or on the surface – their beauty is only skin deep. And as with all beauty, if it does not come from within, it disappears under the slightest of changes. With diamonds, this means the colour may disappear during the faceting process. If, however, the diamond has been through barrages of beta and gamma rays as well as neutrons, the chances are that its green beauty comes from within. In these rare instances, it will sparkle green regardless of the cutting and polishing. Most stones in the green family come from Brazil, Venezuela and Zimbabwe.
Red diamonds are so rare that there is little gemological information about them. What is known is that crystal lattice defects showing stress lamination during the diamond's formation are the main cause of the red colour. While there are some diamonds known as "purplish red", or red with other colour modifiers, a pure red diamond is seldom seen. If you are lucky enough to see a red diamond, you will notice that it does not resemble a ruby, garnet or other red gemstone in colour. The colouring of a red diamond is somewhat sweeter. In some cases, diamonds that appear red to the eye are actually fancy deep or dark pinks. Although the difference between a moderately dark red, a moderately deep pink and a red diamond is at times subtle, the stone and colour saturation that results in the face-up appearance associated with a red is seldom seen. Every fancy colour diamond, apart from red, has the prefix "intense" or "vivid" in their colour grading scale. Red diamonds, though, are never noted as being "intense" or "vivid" because gemological laboratories consider the red colour itself as "intense" or "vivid". The rarity of the gems is reflected in their price. True red diamonds fetch prices of more than seven figures per carat.
Similar to pink and brown diamonds, colour in red diamonds is generally thought to be caused by coloured graining, which results from structural irregularities in combination with an impurity.
