Happy couples on the search for that perfect platinum engagement ring but unable to find the model quite right to suit such a momentous occasion will now be able to 'build' their own item of jewelry.

In the online Bridal Ring Builder service offered by Lewis Jewelers, consumers will be able to formulate their perfect platinum ring by choosing from a wide variety of designs across a range of prices - straight from the comfort of their own couch - perfect for those who are not keen on spending hours on end trawling through jewelry stores.

And with diamonds being a central part of any platinum engagement ring, shoppers will be happy to know they can select the precious stone for them based on factors such as cut, color, weight and clarity.

However, those concerned that the model that they pick out may not look as good on screen as it will do in real life need not worry as rings will be portrayed on a virtual hand, giving users a realistic view on various sizes and styles of jewelry.

Of course if this service doesn't appeal to engaged couples, they will still be able to purchase a whole host of platinum rings from Lewis Jewelers, with designers such as Scott Kay and JB Star making up just a small part of its bridal jewelry showcase.
