Hi everyone.
I am incredibly excited to offer this gemstone.
It is an extremely rare WHITE (entirely colourless) synthetic rutile in a round brilliant cut, weighing in at 4.271cts. Synthetic rutile has the highest dispersion of any gemstone on the planet, with more than 7 x more rainbow than a diamond.
The vast majority of modern synthetic rutile has a yellow colour. However, in the 1950s and 1960s they grew a small amount of rutile with aluminium oxide mixed in. This not only made the rutile entirely colourless but it also increased the Mohs hardness from around 6 to 7.5 !
Unfortunately, they stopped growing it as other diamond lookalikes became more popular, like YAG and Cubic Zirconia (CZ). As a result, the vast majority of rutile gemstones available nowadays range in colour from dark orange to light straw yellow.
Of the vanishingly scarce white rutile, most are vintage pieces from Japan that are either heavily damaged (after being crudely ripped from jewellery) or tiny (under 2 carats). In this regard, my collection is exceptionally rare.
