4.82 ct Sphene Rectangle Cushion SP003

This describes a beautiful and unique sphene gemstone. Here’s a breakdown of its characteristics:

• Species: Sphene (also known as Titanite). This identifies the gemstone, known for its high dispersion or “fire.”  
• Weight: 4.82 carats. This is a respectable size for a sphene, as they are not commonly found in large sizes.
• Dimensions: 11.5 x 8.2 x 5.9 mm. These measurements give a good sense of the stone’s proportions.
• Shape: Rectangle Cushion. The rectangle cushion cut is a stylish shape that combines the rectangular outline with softened, rounded corners, enhancing the stone’s brilliance.
• Clarity: Slightly Included. “Slightly included” means that there are some inclusions visible within the stone, but they are not heavily detracting from its overall appearance. Sphene commonly has inclusions.  
• Color: Yellowish Green. This color description indicates a gemstone with a blend of yellow and green hues. This can be a very beautiful and sought after colour within Sphene.
• Origin: Tanzania. Tanzania is known to produce sphene gemstones, so this origin adds to the stone’s provenance.

Key points to remember about Sphene:

• Sphene is prized for its “fire,” which is the gemstone’s ability to disperse light into spectral colors. This often exceeds that of a diamond.  
• 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.
