This elegant Ceylon sapphire set brings together a 1.00 carat unheated purple sapphire center stone and a round sapphire pair, creating a balanced layout for jewellery design. The center stone measures 6.39 × 5.2 × 3.7 mm and has been fashioned in a cushion step cut, allowing the purple body color to appear with a calm, refined character. Depending on the light and viewing angle, purple sapphire can show slightly different tones to different eyes, giving the stone a natural and personal visual feeling.

The center sapphire carries a “Rebecca purple” appearance, with VS clarity and a soft but noticeable presence. Its cushion shape makes it suitable for ring, pendant, or custom jewellery designs where the main stone needs to feel elegant without being overly large. The step-style cutting gives the gemstone a clean face-up structure, while preserving a calm depth that works well with purple sapphire.

The two round accent sapphires weigh 0.44 carats total and measure approximately 3.6 mm each. They are standard heated, VVS clarity stones, finished in a round flower cut with a Portuguese-style pavilion. Their cutting style adds sparkle and detail beside the center stone, making the full set suitable for three-stone jewellery layouts, side-stone ring designs, or a refined pendant concept.

All stones are from Ratnapura village around mining in Sri Lanka, a historic gem-bearing region known as part of Ceylon’s long gemstone heritage. Sri Lanka has supplied natural corundum, including sapphire in many colors, to the global gemstone market for generations. This set reflects that heritage through both the unheated center stone and the carefully matched accent pair.

Here, gemstones are checked directly with customers from France — close to the source, close to the process, and close to the people who understand each stone.

A fine gemstone collection is not always about one color or one shape. Sometimes, its beauty comes from variety, balance, and the way different stones speak together in one complete layout. This Sri Lanka and Madagascar natural mixed sapphire collection is a good example of that idea. With 25 faceted gemstones and a total weight of 69.00 carats, this parcel brings together a wide range of colors, shapes, and visual moods, giving jewellery designers a flexible and inspiring selection for custom work.

The stones range from approximately 4.00 carats to 1.90 carats each, making the parcel especially useful for jewellery planning where size presence matters. Within the collection, there are 11 pieces above 3 carats, 13 pieces above 2 carats, and 1 piece above 1.90 carats. This gives the parcel a strong design advantage because the stones are not too small for individual settings, while still offering enough variety for matched layouts, statement pieces, rings, pendants, earrings, or multi-stone jewellery concepts.

The color range is one of the most attractive parts of this collection. Blue, yellow, pink, purple, green, orange, red, and other fancy tones appear together in a way that feels lively but still balanced. For a jewellery designer, this kind of parcel works almost like a natural color palette. Some stones can be used as center stones, while others can support a layout through contrast, harmony, or tone variation. The mixed faceted shapes also add design freedom, allowing each stone to be placed according to its own character rather than forcing the entire collection into one fixed style.

Sri Lanka and Madagascar are both important gemstone sources with strong reputations in the colored stone world. Sri Lanka, historically known as Ceylon, is respected for its long gemstone heritage, especially natural sapphires and fancy-color corundum. Madagascar has also become an important source for attractive sapphire material, often producing a wide range of colors suitable for modern jewellery design. A collection combining both origins gives buyers and designers access to a broader gemstone story while still keeping the parcel focused on natural corundum.

This collection includes both heated and unheated stones, which is clearly stated for transparency. In the sapphire trade, heated stones are widely accepted when properly represented, while unheated stones carry their own natural appeal. What matters most is honest description, good clarity, attractive color, and practical jewellery potential. With VS to clean clarity, this parcel has the kind of visual quality that makes it suitable for serious design work and collector interest.

For fine jewellers, this collection offers possibility. It can become a group of individual custom pieces, a coordinated jewellery set, or a colorful design story built around natural sapphire variety. For collectors, it represents a beautiful mixed sapphire parcel with strong color diversity and respectable size presence. For buyers looking for gemstone layouts, it gives flexibility without losing quality.

What is a Ceylon Natural Blue Sapphire? It is a natural corundum gemstone admired for its blue color, durability, brilliance, and long-standing connection to Sri Lanka’s gem heritage. This particular sapphire is a 1.74 ct natural unheated Ceylon blue sapphire, cut into a rare fancy elongated modified shield shape with rounded corners, giving it a unique identity beyond standard commercial cuts.

This gemstone measures 11.06 x 7.18 x 3.05 mm and displays a beautiful blue tone with VVS clarity, placing it in a very clean and high-quality category. The shape is one of the most interesting parts of this stone. It is not a regular pear cut and not a traditional shield cut. The outline carries a long shield-inspired body, rounded corners, and a pyramidal-style top appearance, creating a graceful yet distinctive silhouette.

The journey began as a 4.70 ct facet-grade Ceylon blue sapphire rough, measuring 14.2 × 8.6 × 5.1 mm, freshly sourced from Rakwana village around mining in Sri Lanka through Danu Group’s partner mining connection. The rough showed calm blue tones and natural crystal growth features, with strong potential for precision cutting. After careful planning, the stone was shaped and sourced under Danu Group, with the cutting idea by Mr. Norbert and the final cutting completed by Mr. Jayanath.

The cutting approach was intentionally different. Instead of finishing the pavilion with a sharp standard culet, the bottom was faceted with a softened old-mine-style character, giving the gemstone a more unique personality and a special light return. This kind of cutting direction reflects Danu Group’s approach: not only to polish gemstones, but to create identity, beauty, and individuality within each stone.

The stone is natural and unheated, preserving its original geological character. It is certified by CSL – Colored Stone Laboratory. Certification adds confidence for buyers who value authenticity, treatment disclosure, and proper gemstone identification.

Blue sapphire is the birthstone for September and, in traditional astrological beliefs, is associated with Saturn, Capricorn, Aquarius, destiny number 8, loyalty, protection, love, happiness, and good fortune. These symbolic meanings are based on cultural and astrological traditions, they add emotional and heritage value for many gemstone lovers.
