Description

This 1.37 ct Purple Sapphire from Ratnapura, Sri Lanka, combines a graceful round cut with an elegant violet purple color and the added appeal of being untreated. Sri Lanka is one of the world’s most respected sources for fine sapphires, known for gemstones with lively color, strong character, and lasting beauty. In this stone, natural origin and refined appearance come together in a very versatile and attractive size.

Violet Purple — elegant, lively, and distinctive
The sapphire displays a beautiful violet purple color with a bright and balanced appearance. This refined blend gives the gemstone an individual and sophisticated character, offering something more unusual than the classic blue sapphire while still remaining timeless and wearable. Its color has both freshness and depth, making it especially attractive for collectors and for jewelry designs with a more personal touch.

Untreated — natural beauty without enhancement
This sapphire is offered as untreated, meaning that its color and character have not been improved by standard treatment. Untreated sapphires are especially valued for their natural state and are often chosen by buyers who appreciate rarity, authenticity, and the untouched beauty of a gemstone as it formed in nature.

Round cut — timeless brilliance and perfect balance
The round shape is one of the most classic and enduring gemstone cuts. Its balanced outline and lively appearance make it an excellent choice for jewelry that is both elegant and versatile. A round sapphire works beautifully in solitaire rings, halo settings, pendants, and other fine jewelry designs where symmetry and timeless style are important.

A refined Sri Lankan sapphire for jewelry or collection
At 1.37 ct, this sapphire offers a very attractive size for a center stone, with enough presence to stand out while remaining elegant and wearable. It pairs beautifully with white gold or platinum for a crisp and refined look, while yellow or rose gold can add warmth and individuality. Its combination of Sri Lankan origin, untreated status, and elegant violet purple color also makes it a fine addition to a curated gemstone collection.

A natural untreated Purple Sapphire from Ratnapura with elegant violet purple color and timeless round proportions—ideal for a distinctive custom jewelry piece or a refined sapphire collection.
