Located on Grosvenor Street, Mayfair – Ostro® Topaz oversee the exploration, mining, processing and marketing of Blue Topaz from some of the world’s finest gemstones deposits. Ostro® approached us with an outdated bespoke website that no longer fitted their company image. Their new website design needed to be sophisticated to match their established and highly regarded brand.

"I work in the marketing team for Citibase and we hired Reactive Graphics to design, build and launch a new website for our company in August 2016. Not only was the web site designed and delivered on time and in a very professional manner, we also enjoyed working with the Reactive team."
