Wedded to the world of Ostro® blue topaz, quite literally, the allure of these gemstones has always enticed me.

Being married to Maurice Ostro has brought three incredible children into my life, and a family devoted to this single gemstone…for three generations. So, whilst I have enjoyed my previous roles throughout my career - in law, in business and latterly in HR, it is little wonder that there has always been the temptation to create my own jewellery brand, using our family's very own Ostro blue topaz.
Something Blue by Ostro. And I am so excited to share this with you now.



Our Commitment
Embedded in our DNA is a commitment to care - for our customers, our community and our planet - and to share our success along the way.
The sharing has already started. 10% of Something Blue Ltd has been gifted to charity; the Ostro Fayre Share Foundation and its work helping communities lead better lives together. And our prize possession, the 'Ostro stone' a magnificent 9,381cts flawless blue topaz (the largest of its kind), has been given, on permanent loan, to the Natural History Museum for everyone to enjoy.
With each Ostro Topaz gem we hope the world will shine a little brighter; it's what helps us make every decision.
Something Blue is the coming together of two; a long-held dream to create a brand that married tradition with the unexpected, and a gift that somehow said it all.
The gift was an idea we had to buy a garter, and attach one of our Ostro gemstones to it for a bride-to-be. This was my tradition with a twist - a gift so simple and yet so perfect. 'Something Blue’ for the wedding day, yet playfully wearable every day; a charm-ing reminder of life’s celebrations.
This was the moment that crystallised Something Blue, and launched our journey to create a modern love story, with these most timeless of gems.
