0.37 Ct. Ruby from Thailand

Few gemstones carry the weight of history with as much dignified grace as ruby. From ancient courts to modern ateliers, this stone has been prized for its deep association with passion, protection, and prestige. The small but striking ruby presented here is a classic example of that enduring legacy, offered by The Natural Ruby Company. It is a transparent round ruby weighing 0.37 carat, with dimensions of 4.28 by 4.37 by 2.32 mm. The mixed brilliant cut balances classical proportions with contemporary faceting, delivering a lively play of light from a compact form. Its color reads as pinkish red with vivid intensity, a hue that captures both the warmth of old world treasures and the clarity demanded by modern collectors. Clarity is graded as slightly included when evaluated at eye level, which preserves the stone s natural character while allowing its color and sparkle to remain the primary focus. An excellent polish completes the presentation, giving the surface a refined mirror like finish that enhances both light return and the tactile pleasure of wearing the gem. The stone has been heat treated, a long established enhancement practice, and its geographic origin is Thailand, a source with generations of lapidary skill and a nuanced history of ruby trade and refinement.

For jewelers and clients who conceive of jewelry as wearable heirlooms, the compact dimensions and round shape of this ruby make it an ideal candidate for custom work. At 0.37 carat and roughly 4.3 mm across, it is large enough to serve as a compelling center stone for delicate rings or pendants, and modest enough to be paired as a matched accent in multi stone compositions. The nearly symmetric measurements allow designers to set the gem with confidence in prong, bezel, or half bezel mounts, and the mixed brilliant cut ensures scintillation that will animate even restrained settings. Because the face up color is vivid, the metal choice can be used to amplify different aspects of the stone. Warm metals such as yellow gold will deepen the impression of red, creating a romantic, classic aesthetic, while white metals such as white gold or platinum will sharpen contrast and emphasize the stone s internal fire. The slightly included clarity gives the gem an authentic, natural personality, and it can be showcased alone for a minimalist statement or surrounded by white or color accents, such as small diamonds or sapphires, to create a halo or cluster that magnifies presence without overwhelming the central ruby. Jewelers working with custom clients will appreciate how easily this size integrates into stackable rings, vintage inspired mounts, and modern geometric designs alike, providing a versatile anchor for creativity.

Commissioning a custom piece with this ruby becomes a conversation between tradition and contemporary design, an opportunity to make an object that will be treasured across generations. The historic narrative of ruby as a symbol of devotion and endurance complements the tactile realities of this stone, including its commendable polish and the durable enhancement of heat treatment. At The Natural Ruby Company we understand the balance between disclosure and beauty, and we present this Thai origin ruby with full transparency about its treatment and evaluated characteristics, trusting that informed clients make the most meaningful choices. The compact depth of 2.32 mm paired with the mixed brilliant faceting offers jewelers technical ease when securing the stone, while maintaining a satisfying presence on the hand or at the throat. Whether you imagine a single stone signet or a delicate pendant that draws the eye, this ruby lends itself to bespoke craftsmanship that honors both the gem s ancient appeal and the client s individual story. In choosing this ruby you invest in a piece of gemological history, refined by skilled hands and ready to be transformed into a personal heirloom by a jeweler who values quality, provenance, and timeless design.
