Loose, Imperial Grade Fire Agate

While seemingly subtle upon first glance in artificial light, an undertone layer of blue and purple colors create a highly unusual phenomenon that makes this 4.29 carat Mexican fire agate radiate with a pearlescent glow in the sunlight.  Due to the omnidirectional nature of the stone, this effect can be seen from a multitude of different viewing angles.
Well-calibrated into a near-oval cabochon, not something commonly seen with high grade fire agate, this particular stone is ideal for setting into both a man's or lady's ring.  We strongly suggest making the extra investment associated with gold in lieu of silver, as gold (whether it be yellow, white, or rose) is the most durable option; this stone warrants it.

About Fire Agate

Fire agate is an unlikely volcanic combination of several minerals that find themselves encapsulated in agate, a variety of quartz.  Higher grade stones are iridescent and glow similar to opal, changing vivid colors when held at different angles.  It has become increasingly difficult to find quality gem grade material on the market; the Slaughter Mountain deposit, known for producing some of the world's finest rough, sits within the San Carlos Apache reservation in Arizona.  Outsiders are charged hefty fees to mine with most excursions being fruitless.  Specialists in the field insist what little high grade material is left on the market today is actually older material mined in the 1970's.  This is also believed to be the case of material from the high quality Deer Creek (also Arizona) and Mexico deposits, as well.

While fire agate is not technically a variety of common agate, there are advantages to its close relationship.  Ranking a reasonable 6 to 7 on the Mohs hardness scale, the stone is safe to be worn daily; where the material truly shines (figuratively speaking) is its superior toughness.  Fire agate makes the perfect ring for one who works with their hands and wants a piece of jewelry they can wear all the time.  It can be used safely in both engagement rings and men's rings, as well as make a far more durable alternative to opal.  Fire agate jewelry and stones can be cleaned with jewelry cleaner, ultrasonic cleaners, and steam cleaners. If none of these options are available, soap and warm water is never dangerous.
