SIRIUS STAR, the brightest star in living skies, is a brand new 81 facet diamond cut – not just another branded round brilliant.

Sirius Star Diamond features greater scintillation and increased light return, improved brilliance and higher visual appeal than any other round brilliant. Independent research conducted has revealed that Sirius Star is the preferred choice amongst a broad audience, and an initial production run sold – exponentially quicker than ideal cuts of similar size, color and clarity.

Compared with other round brilliant and other patented cuts, Sirius Star simply stands out from the rest.

The Sirius Star Diamond was designed by Mike Botha (Embee Diamond Technologies) in 2006, drawing on a lifetime of experience and extensive research into what is currently available locally and abroad. Working in close consultation with several leading diamond experts in North America, Sirius Star was born and is the first of several new patented and trademarked diamond cuts designed by Mike.

Getting a little technical – Facet definition is what makes Sirius Star Diamond a superior cut. With 81 facets, Sirius Star features an octagonal main facet configuration and 4-tier pavilion faceting. All the facets are indexed and inclined to present the maximum actual and virtual facet definition. A recent submission of a Sirius Star Diamond to a leading diamond research and identification laboratory in New York for evaluation scored 100% for brilliance. (93% is considered excellent).

    Are you the one in the Hallmark building?

    My wife has a platinum diamond engagement ring. The round diamond is, I think 1 carat, and there is a small diamond on each side of the round. They amount, i think to .25 combined. The ring has been causing problems and rather than fixing the ring I think I prefer to buy a new setting and put the round into it.

    I would like to email you a couple, few, pictures of the ring and get and approximate cost for the ring. The new ring I would like to be white gold and i would like to trade in the old platinum ring to off set a portion of the cost of the new ring.

    Obviously you can’t tell me what the trade in value will bew exactly but you can tell me what the cost will be of the replacement white gold ring prior to what you offer for the old platinum one.

    You need to see pictures of her ring to get an idea of what I am looking for so I need an email address to send them to and you need to make sure it won’t go to your junk email folder.
