2.70 Ct. Blue Sapphire from Thailand

This transparent 2.70 carat oval blue sapphire presents a pleasing balance of size and presence, with precise dimensions of 10.30 x 7.68 x 3.77 mm that make it ideal for a solitary ring, an elegant pendant, or a striking pair of earrings. The gem has been fashioned with a mixed brilliant cut, combining a faceting scheme that enhances scintillation on the crown with a proportional pavilion to retain depth of color, and it has an excellent polish which maximizes surface reflection and tactile smoothness. At eye level this sapphire is graded very slightly included, a clarity designation that indicates only minor natural inclusions that are not detracting to the unaided eye, and which in many cases contribute to the eye appeal and character of natural corundum without compromising durability. The stone exhibits a dark color intensity, offering a deep, saturated blue that performs beautifully under varied lighting and that conveys timeless elegance. Origin is Thailand, a region known for producing sapphires with strong, stable color, and enhancement disclosure is clear, the sapphire has been heat treated, a standard and widely accepted practice in the trade that improves color and clarity in a stable, permanent way when done correctly.

For the educated buyer, several factors make this sapphire attractive beyond its immediate beauty. The 2.70 carat weight sits in a sweet spot where presence is undeniable, yet settings remain practical and wearable, and the oval shape provides visual elongation that flatters many finger shapes and pendant silhouettes. The mixed brilliant cut is chosen to optimize light return while preserving the stone’s rich blue body color, and the excellent polish further increases light performance and perceived depth. A very slightly included clarity grade at eye level signals natural origin and a reasonable price-to-quality ratio, since completely inclusion-free sapphires of similar color and carat weight are exceptionally rare. Heat treatment is fully disclosed and is considered an enhancement that is stable and permanent, commonly used to bring out the intrinsic color of sapphires from credible sources. Provenance from Thailand is a meaningful attribute for collectors and connoisseurs, because Thai sapphires often display a specific tonal quality and are part of a well-documented supply chain, which aids in long term valuation and traceability.

This sapphire’s versatility is one of its most compelling qualities, making it suitable for both casual and formal settings without losing its sense of refinement. In an everyday context the stone’s durability as corundum, with a Mohs hardness of nine, means it resists scratching and stands up well to regular wear when set responsibly and with simple protective design choices. For a formal occasion its deep, dark blue reads as elegant and sophisticated, pairing exceptionally well with white metals for a classic contrast or with warm yellow gold for a more vintage, luxurious statement. The oval outline is inherently adaptable, allowing designers to set the gem in modern bezel mounts for discreet, modern wear, or in traditional prong settings to emphasize brilliance and create a focal point in dressier pieces. Because the sapphire has an excellent polish and a mixed brilliant cut that favors both scintillation and color saturation, it transitions cleanly from day to evening light, maintaining presence without appearing flat or overly dark under dimmer conditions.

When considering value, buyers should weigh the combination of weight, color saturation, clarity at eye level, cut quality, and documented origin, all of which this sapphire possesses in a balanced way. The excellent polish and stable heat enhancement support long term enjoyment, while the Thai origin provides a trusted geographic attribution that many collectors and jewelers respect. At The Natural Sapphire Company we emphasize transparent disclosure and stone education, and we can assist with professional mounting recommendations to maximize both aesthetic and practical performance. If you prefer a bespoke commission, we routinely advise on metal choices and setting styles that protect the girdle and pavilion while showcasing the stone’s deep blue tone, or we can provide certification options and detailed imaging for your records. This 2.70 carat oval blue sapphire is an intelligent choice for buyers seeking a naturally sourced, well-cut gem that balances everyday durability with formal elegance, and who appreciate clear communication about enhancements, grading, and origin.
