SPHENE Vintage Faceted GEM Round Brilliant 1.46 cts fgs71
Vintage round brilliant cut sphene, a faceted gemstone weighing 1.46 carats and with dimensions 7.1 x 4.5 mm.
Sphene is also known as titanite, and is a brilliant yellowish-green, green or brown gemstone with dispersion that exceeds that of diamond. Dispersion is the capacity of a gemstone to separate white light into its component colors, like a prism. The separated light rays travel through the gem along slightly different paths, emerging as distinct colors when they reach the observer's eye. This phenomenon produces the "fire" that makes diamond so attractive and desirable. The dispersion of titanite is about 20% higher than that of diamond, creating a spectacular display of bright colors. Proper cutting is required to optimize this effect.
Sphene is a relatively soft gemstone (5.5 on the Mohs scale, about the same as opal) and is therefore best suited for pendants, earrings or brooches, and not for rings. This relative softness is reflected in minor "paper wear" around the girdle of the stone.
Much of the sphene that reaches the market has a strong body color (commonly green or yellowish-brown) but has not been cut properly and therefore lacks fire. Heavily included material also lacks a strong play of colors because the imperfections interrupt the light traveling through the stone.
This particular stone is from Baja, Mexico. It is a rich brown color and is (typically) lightly included. The cutting is near perfect, with no 'window' to leak light out the back of the stone. The stone appears either brownish or slightly greenish under different light sources.
Sphene is quite rare and only in recent years has enough been mined to serve the modest (so far) needs of commercial market demand. Price is a function of color, clarity and size, and truly clean stones over 1-2 carats are hard to find. The price is for the one faceted sphene, which was mined in Baja in the 1970s. The shipping cost includes insurance.
One of the photographs shows several of the books that Joel has written. The Color Encyclopedia of Gemstones has for more than 30 years been the world's most authoritative source of information on (and pictures of) gemstones, including many of the rare gems, such as andalusite, and all the colors of spinel. Book not included in purchase!

IMPORTANT NOTICE: POSTAGE RATES HAVE RISEN DRAMATICALLY IN 2020
ORDERS INSIDE USA: A charge of $4.00 covers any first class shipment up to 15 ounces. Our beads vary so much in weight that it is impossible for us to apply a single add-on charge for multiple product orders. We will continue to refund to customers any amount that greatly exceeds our actual cost of shipping and handling.
ORDERS OUTSIDE USA: International First Class rates are now crazy: $16.50 for any package weighing from 1-5 ounces. Even an order for 2-3 small bead items may cost $16.50 or more, depending on the type of material (stone versus resin, for example). We apologize in advance if we have to adjust the postage cost of an order that has been placed. We will understand if an order is rescinded when the postage cost is too high relative to the product value.
All international orders have contents described as "loose beads" and are flagged as "commercial samples" or " gift" if you prefer to make your life easier when receiving your beads. If you'd like us to mark your order as " gift" instead please let us know!
All our beads are inspected one by one before being shipped. They are individually wrapped to protect them and then put in little plastic ziploc bags.

Love my beads! The coloring in the epidote was not as intense as illustrated, but it is certainly a good example of the mineral. The colors in the unakite beads are wonderful. The quality of the carving I would rate as good to excellent.
Nice beads!! Super fast thanks a lot!!!
I have dreamed of having a necklace such as the jade one. But the red one. That was a surprise. Both are beautiful. Thank you! Best, Jane
Lovely color;!interesting stones.
When I thought that I had ordered two of these and then checked out I had to order another set. The seller was very kind and combined my two orders and refunded my shipping.
