0.90 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

There is a quiet geography to this yellow sapphire that begins in the ancient landscapes of Ceylon, where pressure and heat over countless millennia coaxed corundum crystals from the heart of metamorphic rock. In that soil, miners guided by generations of local knowledge sifted gravels and inspected veins, tracing the subtle glint that hinted at a gem beneath the earth. From that first discovery, the stone began a journey, moving from the mine to careful sorting rooms where experienced eyes assess color and clarity. At each step hands and traditions shape its destiny, and at The Natural Sapphire Company we honor that lineage by tracing provenance and by treating the story of the gem with the same care we give to cutting and setting. This yellow sapphire carries with it more than mineral history, it carries traces of Ceylonese culture, a long held esteem for bright, clear stones that have been used in ceremonial jewelry, and an enduring sense that light can be stored and worn.

This particular stone is a transparent 0.90 carat oval shape yellow sapphire, its dimensions are 6.85 x 4.91 x 3.19 mm, and it has been fashioned in a mixed brilliant cut to balance face up color with lively scintillation. The clarity grade reads very very slightly included when evaluated at eye level, which means the gem is essentially eye clean and lends a crisp, open window to its saturated body color. The color intensity is medium intense, filled with a sunny, golden lemon tone that reads as joyous without overwhelming, and the polish has been judged excellent, so each facet returns light with bright, lively flashes. The stone has been beryllium diffused, a treatment that introduces beryllium into the crystal lattice during high temperature processing to enhance and stabilize warm yellow hues, and this treatment is fully disclosed in our documentation. The origin is Ceylon, Sri Lanka, and the combination of provenance, cut, and finish results in a gem that is both vibrant and wearable, poised to become the heart of a bespoke piece.

When you imagine this oval yellow sapphire set into a custom design, the ways to pair it with complementary gemstones are inspired by both color theory and the way the mixed brilliant cut plays with light. For a timeless contrast, surround the stone with small round brilliant white diamonds in a halo, their icy reflections sharpening the yellow and adding brilliance to each movement. For a warmer, more romantic palette, pair the sapphire with champagne diamonds or light pink sapphires, the soft tones deepening the golden character and creating an intimate glow. To make a dramatic, modern statement, flank the oval with two tapered blue sapphires, the cool blue placing the yellow at center stage through elegant color opposition. For a vibrant, nature inspired combination, choose green tsavorites or emerald accents, the green and yellow pairing evoking fresh leaves and sunlight. In terms of metal, 18K yellow gold or rose gold will harmonize with the warm hue, while platinum or white gold will lend high contrast for a contemporary effect. Consider settings such as a classic four prong solitaire to show the full oval profile, a low bezel for everyday wear, an east west orientation for a fashion forward ring, or a three stone composition that balances the central oval with delicate side stones.

As your jeweler and guide, The Natural Sapphire Company can turn these ideas into a finished piece that respects the gem and its history, while becoming a wearable part of your own story. The oval proportions of 6.85 x 4.91 mm make the stone ideal for rings and pendants, sitting comfortably on a finger or near the heart, and the mixed brilliant cut ensures lively sparkle in day to day lighting. We practice full disclosure, and you will receive documentation that notes the beryllium diffusion and the Ceylon origin, so you can commission with confidence. Our design process begins with a conversation about how you want the piece to feel, then moves into sketches and metal choices, and finally into the careful setting and finishing that honor the stone. For normal care we suggest gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemicals, and when in doubt you are welcome to bring the piece to us for inspection and cleaning. If you are ready to explore custom options, a designer at The Natural Sapphire Company will be pleased to translate the gem into an heirloom quality piece that carries both the light of Sri Lanka and the personal meaning you choose to give it.
