Editor’s Note
This article explores the rising prominence of Sri Lanka’s parti sapphires, prized for their unique color zoning and ethical sourcing. As demand grows in 2025, these gemstones represent a compelling intersection of natural beauty, investment potential, and sustainable practice.

In the world of gemstones, few names spark as much intrigue as the parti sapphire. With their distinctive color zoning and radiant blend of hues, these rare Sri Lanka gemstones have ascended to prized status among collectors, investors, and jewelry designers. As we move deeper into 2025, their value continues to climb, propelled by both their unique physical features and growing demand for sustainable and ethical mining practices in Sri Lanka.
What is Parti Sapphire? – Defining Parti Meaning and Intrinsic Properties
The term “parti” is derived from the French word meaning “divided into parts.” In gemstone circles, parti meaning points to the striking sight of a single crystal displaying clearly demarcated sections of various colors. Most esteemed is the classic parti bi-color combination: a blend of blue and green, though other stones may incorporate yellow, violet, or even bands of multiple hues. This unique zoning occurs naturally during the sapphire’s formation within Earth’s geological heart.
Parti Sapphire Properties:
– Zoning: Bi-color or tri-color areas within one gem, unmatched among colored stones.
– Durability: Like all sapphire (variety of corundum), parti stones boast exceptional hardness (Mohs scale 9), ideal for fine jewelry.
– Uniqueness: No two parti sapphires are ever identical due to their distinct color arrangements.
– Aesthetic Appeal: Their visual intrigue is highly admired among designers, making them a standout variant in both classic and contemporary jewelry.

Unlike uniform blue sapphires, parti gemstones captivate with their zoning. This feature makes each stone truly one-of-a-kind—with colors that shift in intensity and composition, resulting in both vivid elegance and a signature look for each gem.
The rarity of such naturally occurring zoning increases parti price and desirability, especially in stones that possess both clarity and well-balanced color bands.
Few countries can rival Sri Lanka (Lanka)—the “Gem Island”—for its historic role in the world’s gemstone trade. The island’s rich deposits and unique geological formation both shape the exceptional parti sapphire origins.
The primary global source for parti sapphires is the island’s southern and central belts, regions known for quality crystalline sapphires with distinct zoning.
Parti Sri Lanka gems are noted for brighter hues, consistent hardness, and superior gem-cutting traditions.
Cultural significance: In Lankan traditions, sapphires are often worn for spiritual protection, prosperity, and cultural symbolism. These beliefs have solidified their reputation as treasured family and royal heirlooms.
Historically renowned for being the cradle of the world’s finest sapphires, Sri Lanka stands apart in the market for both beauty and quality of parti stones. The local mining communities have passed down methods and lore, ensuring that the heritage surrounding parti sapphires remains vibrant even today.
How Market, Rarity, and Ethical Practices Influence Parti Price

In 2025, parti sapphire value has surged, reflecting both the growing demand for unique, individualized quality gemstones and the global shift toward sustainable and ethical mining practices. The market for parti Sri Lanka sapphires is especially robust due to:
– Rarity: Large, clean parti sapphires with pronounced zoning are quite rare, dramatically increasing their per-carat price compared to other colored stones.
– Quality Factors: Value is highest in stones with bright, vivid color zoning, clear sections, excellent clarity, and skilled cuts that enhance color transitions.
– Artisanal and Sustainable Trends: The trend toward artisanal jewelry—one-of-a-kind, hand-crafted settings—supercharges demand for parti stones with individuality and ethical origin.
Parti sapphire prices in 2025:
– Entry-level, eye-clean parti sapphires from Sri Lanka: $500 – $1,200 per carat
– Premium stones (vivid color zoning, excellent clarity and cut): $2,000 – $5,000+ per carat
– Larger carat stones with pronounced parti bi-color features can fetch record-breaking prices at auction and among top-tier collectors.
This upward trend in parti price reflects market momentum, heightened collector interest, and consumer willingness to invest in rare natural resources with an ethical supply chain.

For those in the gemstone industry, tracking projected value for 2025 and beyond requires understanding not just supply and rarity.
