Again this is opal has RAINBOW fire that is visible across the opal. This is one of the more beautiful opals we have had the opportunity to offer. Also the luster of this gemstone is marvelous. Many opals only exhibit a couple of colors while this fantastic opal displays a RAINBOW of colors. The fire in this opal shifts depending on the viewing angle. As with all opals it is the most vivid in sunlight or full spectrum lighting. This is a triplet opal where the brightest genuine & natural solid opal is mounted on backing and covered with a protective clear quartz crystal cap. Since triplet opals were not in use in the Deco era this ring probably had the opal added later. We took quite a few photos of this stunning opal under different lighting conditions to give an idea of the abundance and brightness of the fire and where it occurs. The waves and swirls on the opal in the photos are not blemishes but shadows and reflections as the polished surface is difficult to photograph. This Opal is a Rectangular Cabochon Cut. Cabochon refers to a gemstone that has been shaped and highly polished instead of being faceted. This opal is in PERFECT PRISTINE CONDITION free of any cracks, nicks, scratches, or chips. The interior of the ring is also fully hallmarked with an "OB" and a Maltese Cross and the RARE Three Dots which are the hallmarks for Ostby & Barton an extremely collectible and sought after vintage brand. The three dots hallmark in this ring is over the other hallmarks which is something we have never seen. Ostby & Barton, Providence R.I. The business was established in 1879 by Englehart C.
