1.70 Ct. Ruby from Thailand

Among the oldest and most revered of the world of gemstones, ruby has carried the weight of history across empires, ceremonial crowns, and intimate heirlooms. At The Natural Ruby Company we honor that lineage with a fine example of classic beauty, a transparent red ruby that speaks to centuries of admiration and craftsmanship. This gem weighs 1.70 carat, measures 8.25 by 6.25 by 3.50 millimeters, and is fashioned in an elegant oval shape with a mixed brilliant cut. Evaluated at eye level, the stone is eye clean, displaying a vivid color intensity that captures attention without artifice, and it has been fashioned to an excellent polish that allows every facet to sing. The ruby has undergone careful heat treatment, a traditional and accepted enhancement used for generations to enhance clarity and color, and its origin is Thailand, a land with a long and storied relationship to ruby mining and lapidary skill.

The mixed brilliant cut of this oval ruby balances scintillation and depth, creating a play of light that feels both lively and dignified. Where ancestors prized cabochons for their soft glow, this cut brings a modern brilliance while honoring the gemological traditions of proportion and symmetry that have long been associated with fine rubies. The vivid red hue, alive in both daylight and lamplight, conveys warmth and authority, a color that reads as assured and timeless rather than transient. The gem’s excellent polish ensures that its surface is smooth and reflective, allowing the color to appear saturated but nuanced, with flashes of lighter and deeper ruby tones that lend the stone a living quality. The result is an item that feels equally at home in an antique setting that references bygone eras, and in a contemporary design that draws on classical motifs for enduring elegance.

When designing a custom piece around this ruby, the palette of companion stones and metals offers many classical directions that amplify its legacy. For a setting that reads as truly timeless, surround the oval center with a halo of well matched white diamonds in a single cut halo or in a graduated cluster, the cool white of diamonds providing the exact contrast to set off the ruby’s vivid red. A line of old mine cut or antique cushion diamonds will bring a vintage sensibility, while modern brilliant round diamonds will increase sparkle and create a refined frame. For a richer, more historical aesthetic, pair the ruby with green emeralds, an elemental contrast that recalls imperial jewels and the symbolism of life and passion. Emeralds set as shoulders or in alternating accents will intensify the classical story, and tiny rose cut diamonds scattered around the composition will add a whisper of candlelit romance.

The choice of metal and arrangement will further define the piece’s character. Yellow gold will warm the presentation, echoing the ruby’s heart tones and evoking royal regalia, making the gem feel like a relic passed through generations. Rose gold will introduce a soft, romantic glow that reads as subtly modern yet deeply nostalgic. Platinum or white gold will emphasize clarity and contrast, placing the ruby’s vividness at the forefront and lending a crisp architectural quality to the design. Consider a three stone ring with this 1.70 carat oval as the center, flanked by tapered baguette diamonds for a stately engagement ring, or a pendant where the ruby is suspended beneath an antique style diamond bow for a portrait of elegance. For cufflinks or a signet inspired brooch, accent the ruby with scattered small spinels or pink sapphires to create depth and echoes of color that feel curated rather than ostentatious.

Working with The Natural Ruby Company, our approach is to translate the gem’s natural history into wearable legacy, treating each commission as the start of an heirloom story. Given the stone’s Thai origin and its heat treated enhancement, we can guide you on structural choices that preserve and reveal the ruby’s best attributes, while recommending settings that protect its proportions and polishing. Whether you choose white diamonds to set off brilliance, emeralds for regal contrast, or warm gold to heighten the ruby’s glow, the result will be a piece that looks as though it has always belonged to the family it will one day pass to. For those seeking a design that bridges past and future, the 1.70 carat oval from our collection offers an unmistakable center, a voice for tradition, and the adaptability to be paired with complementary gemstones in ways that honor both history and personal narrative.
