Cultivated Emerald gemstones in Columbia green for jewellery making and decoration, available in over forty precise size and cut combinations

This collection of cultivated emeralds provides jewellery makers, hobbyists, and designers with a versatile and consistent gemstone material. The colour is described uniformly as Columbia green treasure, offering a stable base for projects without the colour variation often found in natural stones. With an artificial source, these polished gems are presented in a modern simplicity style, making them suitable for a wide range of decorative and ornamental applications. The comprehensive list includes precise millimetre dimensions and corresponding carat weight estimates for each shape, from delicate 5mm rounds to substantial 12x16mm ovals, allowing for accurate material selection and project costing.
Features and Construction

The defining feature of this product is the extensive variety of cuts and sizes available, all made from the same cultivated emerald material. This allows for cohesive design projects using multiple stone shapes while maintaining colour consistency. The construction involves a polishing process that gives each gem a finished, ready-to-set surface.
Material and Build
The gemstones are made from cultivated emerald, which is an artificially created material sourced to provide a consistent Columbia green colour. The polishing process applied to each stone results in a finished surface described as having a modern simplicity style. This artificial sourcing and uniform processing mean the gems are intended for decorative use, offering predictability in appearance for craft and jewellery applications.
Size and Practical Fit
The product offers a practical range of sizes, with round stones from 5mm to 11mm in diameter, and fancy cuts spanning from petite 4x6mm grandmother cuts to larger 12x16mm ovals. Each listed dimension has an associated carat weight estimate, such as a 6mm round being approximately 0.7-0.8ct and an 8x10mm fat cube around 3.2ct. This detailed sizing allows makers to match stones precisely to specific settings, bezels, or design plans.
Uses and Placement

With their polished finish and decorative classification, these gems are suited to both professional and personal creative projects. The variety of shapes enables use in everything from statement pieces to delicate accent work.
Event or Professional Use
For professional jewellers or designers creating pieces for events, weddings, or collections, the consistency of the Columbia green colour across all sizes and cuts is a key advantage. A designer could use matching 6x6mm princess cut stones in a necklace and complement them with 4x6mm pear shapes in earrings, ensuring colour uniformity. The availability of larger stones, like the 10x12mm oval or 9x9mm heart, provides options for centrepiece stones in rings or pendants.
Everyday Home Use
For hobbyists and crafters, the range of smaller sizes like 5mm rounds or 5x5mm hearts is suitable for home jewellery making, wire wrapping, or embellishing other decorative items. The polished finish means the stones are ready to use without additional processing. The modern simplicity style fits contemporary design trends, making these gems appropriate for creating personalised jewellery, gift items, or decorative inlays for boxes and frames.
Benefits and Buying Value

The primary value lies in the selection and specificity offered by this product, alongside the practical benefits of a cultivated material.
Reuse and Low Maintenance
As single gemstones, they can be set, re-set, or used in multiple projects over time. The polished finish requires minimal maintenance; simple cleaning with a soft cloth can restore shine. Their suitability for decorative use means they can be incorporated into various crafts beyond jewellery, potentially extending their utility.
Why Choose This Product
Choosing this product provides access to a wide catalogue of shapes and sizes within a single colour type, which is particularly useful for projects requiring multiple matching or complementary stones. The detailed size and carat information reduces guesswork when planning designs or purchasing settings. For those seeking a specific look, such as an ash cut or a sugar loaf cut, this collection includes these less common shapes alongside traditional rounds and ovals, offering greater design flexibility than many standard gem assortments.
