3.50 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing presents a transparent 3.50 carat oval blue sapphire, with precise dimensions of 8.63 x 7.24 x 6.44 mm, cut in a mixed brilliant style, graded as very very slightly included when evaluated at eye level, and finished with an excellent polish. The stone displays vivid color intensity, and has been responsibly heat treated, a standard and stable enhancement in the trade that improves color and clarity. This sapphire is identified as originating from Ceylon, Sri Lanka, and has the combination of natural origin, attractive proportions, and a face up color that makes it a particularly compelling choice for a center stone. At The Natural Sapphire Company we disclose both treatment and origin, and we present this gem with clear grading information so a purchaser can assess its beauty and value with confidence.

From a gemological perspective the mixed brilliant cut has been chosen to balance light return with color saturation, and the resulting visual performance is important for a blue sapphire of this weight. The mixed brilliant approach typically employs a brilliant facet arrangement on the crown to maximize scintillation, paired with pavilion faceting chosen to concentrate color, and this is especially effective in an oval outline where table size and facet geometry influence how the color reads face up. The clarity grade of very very slightly included, described here at eye level, indicates that inclusions are minute and do not detract from the gem when set and worn. These internal features are consistent with natural formation, and under magnification they provide identification points that confirm origin and natural origin. The excellent polish contributes to strong light return and a smooth faceted surface, which enhances the perception of depth and saturation.

The provenance of Ceylon, Sri Lanka is meaningful to the informed buyer, because Ceylon sapphires are historically respected for lively, bright blues that often show a pleasing mixture of primary blue with subtle violet undertones. Blue in corundum arises from trace quantities of iron and titanium, and the interplay of these elements with the cutting and depth of the pavilion determines whether a stone reads as vivid, velvety, or more delicate in tone. This particular stone reads vivid in intensity, which means it strikes a balance of saturation and tone that appears strong without becoming overly dark. The slightly deeper pavilion profile in this example concentrates color and produces a rich face up appearance, while the transparency and polish preserve sparkle, so the gem looks alive from most viewing angles.

When considering how this vivid blue sapphire will sit in jewelry, the color offers exceptional versatility across a wide range of complexions, and understanding how it interacts with skin tone helps in selecting metal, setting, and complementary stones. On fair skin the vivid Ceylon blue creates a striking and elegant contrast, lending a clear, saturated focal point that reads both contemporary and classic. For medium and olive skin tones the blue will harmonize with warmer undertones and often reveal the stone as a lively, deep cornflower blue, especially when framed in yellow gold which warms the overall presentation. On darker skin tones the vivid saturation takes on a regal and intense presence, making the sapphire feel majestic and highly visible even from a distance. In terms of metal choices, white metals such as platinum and white gold emphasize the cool aspects of the blue and maximize perceived brightness, while yellow gold softens the contrast and enhances warmth, and rose gold can accentuate any violet leaning in the stone for a unique, modern look. Setting styles matter too, prong settings maximize light entry and sparkle, while a bezel can deepen the perceived color and provide excellent protection for a stone with a fuller pavilion.

For an educated buyer, this sapphire offers both aesthetic and practical value, and the disclosed attributes make it straightforward to evaluate. The 3.50 carat weight combined with an oval outline of these dimensions provides an impressive face up size for use as a ring center, pendant focal point, or in bespoke designs where color is paramount. The heat treatment is a stable, accepted enhancement that improves color uniformity and clarity without compromising the stone structurally, and the Ceylon origin adds provenance associated with a long history of fine blue sapphires. At The Natural Sapphire Company we recommend viewing the stone in diffused daylight and in a warmer interior light to appreciate how the vivid blue interacts with different environments, and we encourage buyers to request gemological documentation if desired. Our team can advise on mounting styles that protect the deeper pavilion while allowing optimal light return, and we stand by transparent disclosure and personalized service to help you select the exact presentation that best complements your style and skin tone.
