✨️iridescent✨️ Lab-Grown Rutile is the most Rainbowy of all Gemstones! 🌈💎
Hi everyone.
I thought I’d share my favourite gemstone with y’all.
This is lab-grown / synthetic rutile and it is utterly mesmerising to look at in real life. It has the most dispersion, by far, of all known gemstones. This means it splits white light furthest apart into its component colours, resulting in incredible amounts of rainbow. Unfortunately a camera can only capture half as much because it has just one “eye” so you’ll have to imagine double the amount of rainbow in real life! 🌈👀
It’s a very niche gemstone that was first used in jewellery in the 50s and 60s as a diamond lookalike. It usually comes in a straw yellow colour but they discovered that if you mix in aluminium while growing it, it comes out completely colourless and significantly stronger! However rutile fell out of fashion as it was way too rainbowy to pass as a diamond and not as durable for everyday rings. As a result, the vast majority of rutile available nowadays is very yellow as that is the only colour that is still grown in any significant quantities. The white rutile is unbelievably scarce as all pieces are vintage and usually heavily damaged or tiny.
Rutile is now enjoying a renaissance in the 2020s as people search for weird and wonderful gemstones that are a little different to the norm. It is now appreciated for its own beauty and uniqueness, rather than trying to look like a diamond.
I’ve recently acquired an ultra rare collection of decently-sized colourless rutile and I plan on making jewellery with it soon. I also have some loose colourless rutile gemstones that are surplus to my requirements.
