At this time natural benitoite gemstones are not enhanced or treated.
With a hardness rating of 6.0 – 6.5, this durable blue gemstone does need some special care. It should only be cleaned with a soft cloth that is free of dust and fine debris. Cleaning methods using heat, ultrasonic machines, and chemicals should be avoided. In time, like other types of gemstones it may need a professional cleaning and polish to restore its natural luster. Care should be taken to avoid scratches.
Because exposure to heat, ultrasonic machines and chemicals can damage the gemstone, white gold with rhodium plate should be avoided - as the replating process could damage the stone. Instead, stick with platinum, palladium or red/yellow gold.
This gemstone is currently mined in California, Arkansas, and
Japan, although most gem quality stones are only found in California.
Current prices are on average $3,000 per carat. Smaller carat sizes come out to an average of $700 per carat; the cost per carat rises dramatically according to its size since one carat or above gemstones are rare.
Prized benitoite gemstones have the characteristic deep dark blue associated with this gem, in addition to depth, fire, and brilliance.
Cut is also important to the overall value of the gemstones, as is the absence of any inclusions or blemishes.
This gemstone was named for the “Benito” area in California where
it was first discovered. The term “Benito” means blessed,
and as a result those who are lucky enough to own a fine specimen of
this gemstone should considered themselves fortunate and blessed.
Gemstone Shopping Tips
Synthetic gemstones of this kind have been grown in laboratory settings, but only in very minute quantities. On today’s market, no synthetic exists but buyers still need to beware (while not common, some disreputable sellers try to sell colored cut glass as authentic gemstones).
To ensure that you are purchasing a genuine gemstone, pay
attention to price, seller reputation, and a light fluorescence test:
These gemstones are not readily available already set in a gemstone ring, if you would like an engagement ring or wedding ring featuring the famed "Benito" gem, you will probably need to purchase the stone rough - or for fun, try finding benitoite on one of the gemstone vacation tours offered in California - and have the stone cut.
If you have a rough benitoite gem that needs to be cut and fit
into a ring, make sure that you only take the gem to a jeweler who has
experience working with this gem.
