• It has a relatively lower hardness on the Mohs scale, which means it requires careful handling.  
• The color variation of yellow/green is quite common, and adds a nice display of colour.
• Because Sphene is not always found in large clean stones, this size of 4.82 carats, is a good sized specimen.

In summary, this sphene is a lovely gemstone with a desirable color and a unique cut, originating from a respected source.
