| Vintage Japanese 1.90ct Mexican Fire Opal \u0026 Diamond Ring in Platinum, c.1970s","description":"\u003cdiv style=\"text-align: center;\"\u003e\n\u003cem\u003e\u003cstrong\u003eCrafted in Japan during the later mid-century Shōwa era, c.1960s–1970s, Dewdrop is a vintage platinum ring centered by a 1.90-carat natural Mexican fire opal. Mexican fire opal enjoyed particularly strong demand in Japan during this period, and Dewdrop reflects the ornamental jewelry made around these unusually transparent stones: a dramatically high-domed opal elevated above an intricate diamond-set platinum setting so that its color can be seen not only from above, but rolling around the sides of the stone as the hand moves.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eThat three-dimensional quality is central to Dewdrop. Measuring approximately 8.49mm by 6.67mm and nearly 4.85mm deep, the opal rises like a polished drop of glass above the setting. Its transparent, warm light-orange body carries vivid play-of-color dominated by green and red, with occasional orange and subtle blue appearing as the stone moves through different angles of light. Rather than presenting its strongest display only from directly above, color can travel across and down the curved sides of the high dome.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eLighting changes the ring considerably. In bright studio lighting against a dark background, the opal can reach the intense green and multicolor display seen in our photographs, representing the stone near its brightest. In natural sunlight, its warm transparent body becomes more apparent while concentrated areas of green, red, and orange move through the stone with the direction of the light. It remains attractive in softer indoor conditions, but its finest color is revealed in brighter light and with movement. Our sunlight photographs and video provide the most representative view of its everyday optical character.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eFourteen natural diamonds surround the opal, including two long tapered baguettes and twelve round brilliant cuts totaling approximately 0.13 carat, with an average clarity of VS2. Their restrained arrangement adds crisp white brilliance without overwhelming the center stone. Beneath them, open platinum work supports the unusually elevated setting while allowing light and visual space around the opal.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eSourced from one of OpalPop’s established Tokyo estate-jewelry sources, Dewdrop retains its original Pt900 hallmark together with “190” for the inscribed opal weight and “D013” for the diamond weight. The ring has been professionally cleaned, its platinum polished, and the center stone tightened by our Anaheim, California jewelry partner.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eDewdrop is best understood as an ornamental piece of vintage fine jewelry rather than an everyday ring. Its exceptionally high profile and exposed natural opal reward careful, occasional wear. At approximately size 8.25 US, it is also unusually generous in size for a vintage Japanese ring, making it particularly appealing to collectors who often find smaller estate-jewelry sizes impractical.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eApproximate default ring size 8.25

around the 1980s, Shannon is a vintage platinum engagement ring centered by a 2.26-carat natural Australian semi-crystal opal.  Its design reflects the Art Deco influence often seen in later Shōwa-era

unusually fluid play-of-color that changes significantly with movement and light.  In softer conditions, blue-green and green predominate, with a localized area of warmer color appearing more subtly

established Tokyo estate luxury-goods contacts, the ring reflects a distinctive period in Japanese fine jewelry—one in which the angular influence of Art Deco met the increasingly ambitious platinum workmanship of postwar Japan.  Beneath the stone, sharp architectural lines soften into hand-curled openwork filigree, creating a setting that is almost as compelling from the side as it is from

an inch long and nearly half an inch wide—its elongated oval silhouette dominates the finger without losing its elegance.  The natural Australian light opal has an N8 body tone and displays full-spectrum play-of-color, with orange and green most prominent alongside complementing flashes of yellow, blue, violet, and red.  Across its broad surface, different areas reveal broad flash, smaller flashes, and narrow bars of electric color, giving the stone a varied appearance as it

appear quiet and pastel; under stronger light, and especially in sunlight, the stone becomes considerably more animated.  That changeability is part of its character.  Rather than remaining visually constant, it rewards movement and changing light with new areas of color across its unusually expansive face.  The opal is Australian in origin and is attributed, though not documented, to the Coober Pedy mining region.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eTen natural round brilliant-cut diamonds—five along each side—frame the opal in two

unmistakable presence of vintage Japanese luxury jewelry.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003ePrincess Tsume is for someone drawn to jewelry

 Its scale is immediately noticeable, but the setting is what gives the piece its authority: more than ten grams of solid .900 platinum rise into a high, intricately worked gallery, with scrolling filigree flowing outward into diamond-set shoulders.  The construction feels substantial and deliberate without losing the elegance expected of vintage Japanese fine

 Green dominates its play-of-color, accompanied by blue-green, teal, blue, and smaller flashes of yellow that can warm toward orange in stronger light.  Its pattern is distinctly directional.  Broad areas of color can become intensely saturated at favorable angles, while other portions of the stone return to quieter transparent crystal as the ring moves.  That contrast gives the opal a changing

opal, five to either side, with a combined weight of approximately 0.22 carat and an average clarity of VS2.  Their arrangement is integrated into the architecture of the setting rather than simply

confident platinum workmanship associated with late-Shōwa Japanese jewelry.  The ring has been professionally refurbished by our Anaheim, California jewelry partner, including cleaning, light platinum

subtle orange and pinkish-red color moving across the opal alongside occasional green and blue.  Under brighter light and sunlight, the pinkish reds become more prominent and blue strengthens considerably, joined by green, orange and flashes of yellow from sharper angles.  The effect remains refined rather than intensely bright; this is a large opal whose appeal lies as much in its scale,

characteristic of mid-century Japanese platinum jewelry.  Six natural diamonds totaling 0.22 carat are arranged across split shoulders, with one marquise-cut diamond framed by two round brilliant cuts on each side.  Their slightly elevated, outward-facing placement allows the diamonds to contribute to the ring’s top-down silhouette rather than disappearing into the

platinum construction feels substantial at approximately 8.08 grams, while the shank carries an unusual frosted center stripe bordered by polished platinum.  This textured treatment continues toward the split shoulders and has been observed on other older Japanese platinum rings of the period, giving Patricia additional visual detail even away from the center

the platinum alloy, total diamond weight and opal weight.  The “Pm” hallmark and Pt850-era construction support a conservative mid-century dating of approximately the 1950s.  Patricia was sourced

the face of the stone.  It can be difficult to notice in softer light but becomes more apparent from certain angles under brighter illumination.  Because the fissure begins near a prong, its exact origin cannot be determined with confidence; it may be natural or may have occurred during an earlier setting process.  The opal’s substantial thickness helps preserve the overall integrity of the stone, but this remains a vintage opal ring that should be worn with particular care and protected from

vintage Japanese platinum engagement ring centered by a substantial 4.83-carat Australian light opal whose scale is immediately impressive, yet whose overall character remains soft and romantic.  Measuring approximately 14.55 × 11.86mm, or about 0.6 × 0.5 inch, the oval opal covers a broad portion of the finger while its pale N8 body tone keeps the effect luminous rather than overpowering.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eThe opal’s play-of-color is subtle but unusually complex.  Its surface is naturally divided along a loose diagonal, with one side tending toward green and the other toward soft orange that can shift into pinkish red in brighter light.  Pearlescent blue appears throughout, while flashes of purer orange sometimes emerge within the greener areas.  The result is less a single dominant color than a gentle interaction between pastel green, pink-orange, and blue across the stone’s semi-crystal body.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eJasmine is generally quieter indoors and in lower light, becoming most animated in

softness.  Split shoulders rise toward four small round diamonds while openwork filigree curls through the gallery beneath the opal.  From the side, the design loosely forms heart-like shapes within the filigree, while the angular shoulders retain the Art Deco-influenced geometry often seen in Japanese jewelry of the late Shōwa era.  From above, however, the overall silhouette remains rounded and

is an unusually transformational opal ring.  In subdued indoor light, its 1.43-carat Australian semi-crystal opal can become remarkably quiet, with only restrained traces of blue, violet, and green visible through its translucent body.  Under stronger, favorably directed light, however, the same stone changes dramatically.  Green begins to intensify across the opal, reaching a vivid, almost

presenting constant brightness, the opal moves between a soft, nearly dormant appearance and sudden flashes of saturated color as the lighting and viewing angle change.  Its play-of-color is highly directional, rewarding movement and direct light rather than revealing its strongest display in every environment.  The stone is Australian in origin and is attributed, though not documented, to Lightning Ridge.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eSurrounding the opal is a distinctive mid-century Japanese ballerina setting formed from sixteen natural diamonds totaling approximately 0.42 carat.  Tapered baguettes fan outward from either side of the center stone while round brilliant-cut diamonds complete the surrounding spray, giving the ring a lively asymmetry and considerable visual presence despite its compact proportions.  Beneath the diamonds, curled openwork filigree continues through the gallery, adding the intricate platinum detailing associated with vintage Shōwa-era jewelry.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eThe ring is crafted in solid .900 platinum

from one of OpalPop’s established Tokyo estate-jewelry sources, Midori has been professionally refurbished by our Anaheim, California jewelry partner, including cleaning, platinum polishing, and tightening of the center stone.\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eWith a default size of 4.75 US, Midori is especially well suited to a

Australian dark opal.  Crafted in Japan during the later Shōwa era, approximately the 1970s–1980s, the ring surrounds its center stone with an elaborate radiating arrangement of forty natural diamonds totaling approximately 0.70 carat.  At just under two-thirds of an inch across the face, it has the unmistakable presence of a serious piece of vintage fine jewelry.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThe opal is an N6 gray-based dark opal whose play-of-color is best appreciated in motion.  Red is its strongest color overall, joined by orange in softer light, while blue becomes increasingly important under brighter illumination and in sunlight.  In favorable light, the blue can become nearly as visually dominant as the red.  Green appears more sparingly, emerging as a subtle secondary overtone that comes and goes across different parts of the stone.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eUnlike an opal dominated by one broad flash, Fuji’s color appears in distinct, independently moving sections.  Individual areas illuminate and disappear at different moments as the ring turns, creating a display that is much more continuous in person than a still photograph can capture.  Fine linear boundaries visible within the stone separate these regimented areas of color play; they are internal color-bar features rather than fractures.  The accompanying video provides the closest representation of this movement.  The opal is Australian in origin and is attributed, though not documented, to Lightning Ridge.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThe ballerina setting is unusually diamond-rich.  Three tapered baguette-cut diamonds radiate from the north, south, east, and west positions, while groups of round brilliant-cut diamonds fill each corner, creating the characteristic pleated, fan-like appearance of the style.  The forty diamonds average approximately VS2 clarity and H-I-J color, giving the setting considerable brightness without obscuring the opal at its

appear across nearly the entire face, accompanied by blue undertones and delicate touches of yellow and orange.  Rather than concentrating its best color into one privileged viewing angle, the opal is notably non-directional: its brightness and extensive play-of-color coverage remain consistent as the hand and viewing position change, with very little of the broad rectangular face becoming visually inactive.\u003c\/p\u003e\n\u003cp\u003eIn subdued ambient light, the depth of the translucent body becomes more apparent and the opal takes on a quieter, darker character.  Bluish-green flashes remain

both alongside and seemingly suspended over one another through the depth of the opal.\u003c\/p\u003e\n\u003cp\u003eDirect artificial light and sunlight reveal its most vivid presentation.  The broad face becomes covered in bright, twinkling patches of green and blue, while yellow-green can shift toward delicate yellow and occasional orange.  Under certain strong illumination, another effect appears beneath the play-of-color itself: the thick translucent body develops a warm orange-to-pink glow as light passes through it.  This is transmitted light within the opal rather than
