Sphene is one of those magical gems that can really enchant you—the best faceted examples display brilliant fire and flash three different colours.
Sphene is a very rare calcium titanium silicate that is hardly ever seen in jewellery or collections. Sphene is also called ‘titanite’. which derives from the fact that it is an ore of titanium. The name sphene comes from the Greek word for wedge, which describes the shape of the ends of sphene crystals. Sphene has been prized for many years, mostly for its high amount of fire and brilliance, however its scarcity always prevented it from becoming well known. Now, new sources of the stone are being found, and we are starting to see slightly more availability. Most of the sphene today comes from Brazil and Madagascar, some from Austria and Switzerland. Sphene is usually very small, as gems of more than two carats are almost impossible to find.
Gem-quality examples are rare; it is a collector’s gem and is particularly rare when you start talking about a clean stone above 5 carats, as is the case with all gemstones, size creates a premium with this species. It has more “fire” than a diamond the gemstone has one of the highest dispersions of any mineral; the term dispersion refers to a mineral’s ability to break white light into spectral colours and therefore shows intense fire, showcasing multiple colours, especially when it’s well-cut. It’s 5 to 5.5 on the Mohs scale, making it softer than other, more well-known gems so ideal to be set in a pendant or earrings. It comes in a variety of hues, but some are preferred.
Sphene’s typical colour range is yellow, green, orange and brown. There are also pinks and reds, which are rarer, as well as some black and colourless material. However, the gemstone is vibrant in an almost lime green hue that also shows flashes of orange and yellow.

Brilliant personal service every step of the way. I wanted a diamond engagement ring and was able to easily discuss different stones and design options with Grace sending sketches back and forth. I decided on an emerald cut stone with a platinum ring. Communication was excellent and the ring delivered on time and discreetly to an agreed address. I proposed by Lake Windermere having hidden the ring in the sandwich tin. A beautiful ring - my partner loves it!
My wife and I purchased a lovely bespoke entwined engagement & wedding ring from Michael Platt, 28 years ago. We visited in February this year to enquire about an eternity ring. Jordan was inspirational and used diamonds from a family heirloom. The design full complemented and sits beautifully with the original rings. It was a very pleasurable experience and we are both delighted with the result. Fantastic to know they are still offering great service and bespoke design.
I have had two stunning pieces of jewellery made by Michael Platt. One is a beautifully intricate diamond pendant and the other a spectacular dress ring reusing my own stones that have a lot of sentimental value. I am thrilled with both pieces. Wayne listened carefully to all my (very detailed!) requirements and followed them to the letter. This is a highly skilled team with amazing attention to detail and wonderful service. I am an absolutely delighted customer!
The service we have received here has been second to none.
We first came to the shop a few years ago and had my engagement ring designed and created. It really is incredible what they do. The design was perfect to me and my style and the final product exceeded our expectations. So much so we finally came back recently and had both wedding rings made. Thanks again to the members of staff at Michael Platt you really are a fabulous bunch and make dreams come true!
I have had several pieces designed by the lovely staff at Michael Platt in Wimbledon. The pieces have been much admired. My first visit was several years ago so when I wanted something designed and made with stones from other pieces of jewellery which were very sentimental I had absolutely no hesitation about bringing the project to the shop in Wimbledon. The staff are so helpful, warm, welcoming and informative. Great service and a delight to do business with. I have never been disappointed.
