Square Gemstones        

It is often said that square gemstones never go out of fashion and this is quite true. The popularity and demand for square gems would have been much more if, all gemstones could easily be found in square shapes. While there is no reason why any gem cannot be cut to a square shape, technical implications play a part.

The specific shape and proportions of a square shaped gem stone are such that, substantial weight loss is experienced during the cutting process. When the gem cutter starts cutting a particular piece of gemstone rough, he starts off with the weight of the rough. In most cases, 70% or more of the original weight is actually lost and the final cut stone weighs just 30% of the weight of the original rough gem stone. The final cut gem will be costed at the original weight + cutting charges + profit margin. Square shaped gemstones can involve a cutting weight loss of upto 85%. Since most gems are sold per carat (by weight) the price per carat of square shaped stones will be quite stiff. This is the reason why expensive gems like rubies, sapphires, emeralds and even tanzanite are generally not cut in square shapes. This becomes even more clear when you try to find these gems in square shape and size above 7mm.

If you talk about square shaped gems, it is important to mention princess cut diamonds and other gems too. The princess cut is basically square in shape and includes very specific details for facets and angles of cut. Princess cut diamond rings are a hot favorite for special occassion jewels like wedding and engagement rings. It is not only diamonds that can be cut in princess cut style, basically any transparent gem could have a similar cut.

There is one thing about square shaped gemstones that you should be aware of. The jewelry design that uses square gems needs to give special attention to the corners of the gemstone. The pointed corners of a gem cut in square shape are prone to breaking and chipping if struck with physical impact. This will remain true even for hard gems like ruby and sapphire. A researched jewelry design should protect the corners of the square stone. This can be done by covering the entire border of the gemstone with metal or by using sturdy right angle prongs on each corner. Do not neglect this requirement, as a damaged gemstone can sometimes be very expensive to replace or repair. In the case of rubies and sapphires, it is not uncommon for the gem to have a value that is higher than the value of the gold in the ring.

The shape of square gems is can facilitate firm gem stone mounting in a jewel too. When a square stone is mounted in a gold or silver jewel, the entire flat edge (all the 4 edges) can rest firmly against or in the metal. Channel setting is a good example to explain this better. If you channel set a round or oval gem stone, it is only a portion of the curved edge that will actually sit snug in the mounting. You could therefore say that a well set square gem stone can add to the durability of the jewel.

At Kaisilver every gem stone is handpicked and closely inspected before being cut by very skilled craftsmen. We do not produce tonnes of gems, only the best stones for the price paid are handpicked and offered to our buyers. You can order just the gemstone or request for a complete custom jewel to be made.

Who Is Kaisilver?

Having established itself as the world's leading online custom jewelry provider, Kaisilver now extends it's merchandise line to include gems. While there is no shortage of gem stones in the global market, reliable sources for the retail buyer requirements are not many. Most retail gem dealers work with limited inventories, this reduces buyer options. Another problem with these small dealers is the lack of information and reliability when it comes to gem authenticity and value for money. Kaisilver with it's wide network of gemstone mining and manufacturing resources, is the best source for gems of all types, shapes, sizes and cuts. With a support team that is compromised of jewelry and gemstone experts, the advice and suggestions made by the team relate to your requirements and not to fixed sales targets. The website shows a small sampling of the gems that we offer. You can infact request for just about any gem on the globe. All gems are sourced directly from the source, closely inspected and then custom cut by our expert cutters. With a buyer base that includes fashion models, government officials, casino and resort owners, lawyers, financial experts, students and professors, doctors and surgeons, sportsmen and newsreaders we have become the preferred choice for quality gems and jewelry. By cutting out middlemen commissions and multiple agents, we provide great value for your money. Our large online operation does not stop us from welcoming even the smallest order. Gold and silver jewelry is custom made with equal attention to quality, material and craftsmanship. You can choose from our designs or send us detailed for the style and design that you need.


How To Order?

The process to order gems and custom jewelry at Kaisilver is similar. We do not expect you to make a rush purchase. We do wish that you take the time to discuss your requirements with our experts. They will be in a position to provide constructive suggestions that will guide you to make well informed buying decisions. Email all your requirements to provide as much inputs as possible to help us make relevant suggestions. For example if you are keen on getting a green gemstone but, are not particular about it being an emerald mention this in your email. Our gem experts might suggest a green tourmaline or even a peridot instead of an emerald. This suggestion would reduce our profit margins but will give you a gem that, is much cheaper and even more durable as compared to an emerald. When it comes to payments we offer some very suitable options. Paypal is the preferred form of payment, it is fair to the buyer and seller. The buyer when using paypal never needs to reveal credit card of bank information to the seller. We also accept direct bank transfers but prefer to do this on a case by case basis. When it comes to online transactions these days, both buyer and seller are afraid of frauds. It is quite possible that you do not feel comfortable working with us at Kaisilver. We sometimes feel a little uncomfortable with certain transactions too and prefer to keep away from them. There have always been fears of processing payments through Western Union money transfers. With the latest fraud reports, fake sellers and even fake buyers have been pulling off many online frauds using this mode of payment. At the same time we do understand that armed forces from the U.S who are stationed in various global positions sometimes have no other mode of payment besides Western Union. We therefore accept this mode of payment but at the same time, request you to avoid this mode if you do not feel comfortable using it. Shipping is done through FEDEX and you can expect a production lead time of around 4 to 5 weeks from the date of order confirmation and receipt of payment. Every jewel is fully custom made and requires the complete attention and concentration of highly skilled craftsmen. When it comes to gems, we could provide faster lead times and this can be discussed for each specific order.
