Ruby is a variety of Corundum coloured by trace amounts of Chromium. Highly prized since centuries in Europe and Oriental countries equally. Rubies are one of most expensive gems and regularly attain record breaking prices at auctions. When valuing Ruby colour is most important, rich red with a touch of blue being most expensive. Second comes clarity that will enhance light reflection making stone more brilliant and sparkly. Clean Rubies are very rare, even in high quality parcels and most will show some inclusions. Stones over 2ct are rare, over 5ct can command almost any price. Rubies can be enhanced in a lot of ways. Heat treatment is widely accepted as about 95% of all rubies are heated to some degree. It is stable and practiced for generations. Fracture filling is used to heal surface reaching fissures by filling them with flux that turns to synthetic ruby. Stable if preformed correctly but it affects the price quite significantly. Some modern practices include filling rubies with lead glass (often coloured). Cheap and not very stable treatment used to turn non gem quality material into saleable commodity. These stones can be damaged by heat in jeweller's workshop; acids- including as mild substances as lemon juice and by everyday mechanical wear since lead glass is much softer than Ruby. Value of lead glass filled Rubies is very low and we don't recommend using them in general. Synthetic Rubies are also commonly used in jewellery after being first produced in 1840's. We only stock natural untreated or heated rubies and always offer you a full disclosure.

Pictures- All Images used by us represent the actual item on sale unless stated otherwise.

Please note that our images usually show objects in high magnification as to enable you to inspect them in close detail, the actual measurements are given in products' description and you should reflect on them while considering the purchase. Pictures showing gems are many times their size and may show you more imperfections (inclusions, imperfections of cut and polish) than you will see while holding the same gem in your hand. Certain gems like opals do not look the same under different lighting conditions or from all directions and in such case we chose the best shots to show potential of the stone.
