Golden Sphene, also known as Golden Titanite or Yellow Sphene, is a rare and beautiful gemstone. Here's some information about it:
Appearance: Golden Sphene is known for its intense golden-yellow to orange-yellow color, which is its most distinctive feature. It has high transparency and is typically faceted to enhance its brilliance.
Mineral Composition: Golden Sphene is a variety of the mineral titanite, with its chemical formula being CaTiSiO5. It belongs to the group of nesosilicate minerals and has a hardness of 5 to 5.5 on the Mohs scale.
Origin: The primary sources of Golden Sphene are Sri Lanka, Madagascar, Brazil, and the United States. Sri Lanka, in particular, is known for producing high-quality Golden Sphene gemstones.
Brilliance and Fire: Golden Sphene has excellent dispersion, which is the ability to split white light into spectral colors, similar to a diamond. It exhibits a remarkable play of colors, displaying vibrant flashes of yellow, orange, and green when viewed from different angles.
Rarity and Value: Golden Sphene is considered a rare gemstone, and its value is influenced by factors such as color, clarity, size, and overall quality. Larger, eye-clean stones with intense golden color command higher prices.
Durability and Care: While Golden Sphene is relatively hard, it is also a brittle gemstone. It requires careful handling to avoid accidental impacts or scratches. It is recommended to store Golden Sphene separately from other gemstones to prevent any potential damage.
Remember that obtaining gemstones, especially rare ones like Golden Sphene, should be done through reputable sources. Gemstone certification from reputable gemological laboratories, such as the Gemological Institute of America (GIA) or the American Gemological Society (AGS), can provide assurance regarding the authenticity and quality of the stone.
