High Quality Diamond Simulant
Indistinguishable from a Mined Diamond by the Naked Eye |
Diamond simulants are graded by the 'A's Scale...'A' being the lowest quality and '6A' being the highest. There is a vast difference in the quality between the 'A's and also variations of quality from the manufactures. All our stones are either 5A or 6A
We guarantee that our stones are of the highest quality...We also guarantee that multiple purchases of the same same stone will be a true match in: colour, cut and size...value for money we cannot be beaten.
True proportion to the cut of a diamond (depth x width) is essential for the maximum reflexion of light, which will give the stone brilliance and fire. Proportion is also important if you are fitting loose gemstones into jewellery as the setting will be made to only accept a well proportioned stone.
All our simulated diamonds are manufactured and cut, faceted, in laboratories in the USA. These laboratories are now recognised for producing far superior diamond simulants than Russia or the far east. This ensures that only the highest quality are offered for sale. We feel sure that you will not be disappointed with your laboratory created diamond .
Do not confuse our diamonds with cheaper, lesser quality stones, which may fade and discolour over time. These are high quality diamonds, with similar properties to a mined diamond. They are extremely hard. Their sparkle and lustre is permanent, looking superb when mounted in any type of jewellery, or just left loose for whatever purpose you may have. Jewellers find it difficult to tell the difference between high quality lab diamonds and mined diamonds without the use of specialised testing equipment. In the last decade, technology has improved to the point that diamonds can be produced in the lab that are equal in quality to any mined diamond. Lab created diamonds are quite simply, simulated diamonds that have been produced in a lab rather than those that occur naturally and are mined out of the ground – Reviews of Simulated Diamonds The table given below enlists the different types of Lab created diamonds, along with the different properties they possess. In order to be able to compare these properties with those of a real diamond, take a look at the properties of a real diamond enlisted here.Simulated Diamond Reviews | |||||
