0.87 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This transparent 0.87 carat round color change sapphire presents precise proportions that are suitable for a refined custom piece, with dimensions of 5.55 x 5.54 x 3.73 mm, a mixed brilliant cut, and an excellent polish, all supplied by The Natural Sapphire Company. The gem is graded as very slightly included when evaluated at eye level, a clarity characteristic that permits a high degree of light return without obscuring the table or the pavilion, and it displays a medium intense color intensity that reads as lively without becoming overly saturated. The stone is completely untreated, with no enhancement reported, and its origin is Ceylon Sri Lanka, an area noted for producing sapphires with balanced tone and attractive color range. These factual attributes are presented to allow precise assessment for designers and clients who require accurate specification before committing to a setting or combination.

Under differing lighting conditions this sapphire demonstrates a distinct and noticeable color change, which is an essential factor in both aesthetic planning and daily visual experience. Under fluorescent or daylight balanced lighting the gem takes on cooler violet and lavender notes, while under incandescent lighting it shifts to a warmer pink to rose pink expression, as visible in the provided images. The mixed brilliant faceting pattern contributes to lively scintillation and controlled light dispersion, so the color change is supported by flashes of brightness that emphasize the shifts between purple and pink. The medium intensity of color allows both tones to be visible without one overpowering the other, making the gem versatile for settings intended to read differently in varied environments.

From a durability and handling perspective this sapphire is well suited to conventional jewelry applications, and the mixed brilliant cut combined with very slight inclusions indicates stable cutting and polishing practices. Sapphire is a hard and durable material, appropriate for daily wear in rings and bracelets provided the setting affords typical protection to the girdle and pavilion. The very slight inclusions noted at eye level should be considered when choosing a setting style, since open prong placements can showcase the stone without risk, while bezel or half bezel mounting can provide enhanced edge protection if desired. The excellent polish reduces surface wear and improves overall brilliance, and the lack of enhancement simplifies long term care, as there are no treatments that might be affected by routine cleaning and maintenance.

When planning a custom piece around this 0.87 carat color change sapphire there are several complementary gemstone strategies that both respect the stone fundamentals and enhance its color behavior. For a classic and restrained approach use white diamonds as accent stones to increase perceived brightness and contrast, such as a single row halo of small brilliant cut diamonds or tapered baguette shoulders to elongate the finger in a ring. For tonal harmony consider pink sapphires or rhodolite garnets, which will reinforce the warm pink side of the color change under incandescent light, creating a cohesive appearance across lighting conditions. To enhance the cooler violet character pair with purple spinel or amethyst for a deeper violet field under daylight lighting. For a sophisticated color interplay use small alexandrite accents that exhibit their own color shift, producing a layered chameleon effect that is particularly striking in pendants and cluster rings.

Metal choice and proportion are important when specifying a bespoke design for this stone, because metal color will influence how the human eye interprets the sapphire color in situ. Warm metals such as 18 karat rose gold will subtly amplify the pink component of the stone, making the sapphire read warmer in mixed lighting, while 18 karat yellow gold will provide a rich backdrop that complements both pink and violet tones. Platinum or 18 karat white gold will emphasize the cooler violet appearance and deliver a contemporary, high contrast presentation, particularly when paired with white diamond accents. In terms of layout the 0.87 carat center stone balances well with a halo of 0.01 to 0.03 carat diamonds, or with two shoulder stones each in the 0.10 to 0.20 carat range for a classic three stone composition. For a pendant, small pavé accents around a bezel or open cup will permit light to pass through and highlight the color change, while for earrings matched pairs of small color change sapphires or a pairing of this sapphire with complementary stones can create coordinated sets that read consistently across different lighting environments. The Natural Sapphire Company can provide additional technical specifications and imagery to assist in finalizing metal choice, accent size, and setting type to achieve the intended visual outcome.
