These lab-grown gemstones have the same physical and chemical properties as natural sapphires, making them almost indistinguishable to the naked eye. However, gemologists can often identify them through specialized testing.

One of the main advantages of lab-grown sapphires is their affordability compared to natural sapphires, which can be quite expensive due to their rarity and the cost of mining. Additionally, lab-grown sapphires are considered more environmentally friendly since they do not require extensive mining and have a smaller carbon footprint.

What’s the difference between natural and lab-grown gemstones?


The primary difference between natural and lab-grown gemstones is their origin. Natural gems form over millions of years within the earth through geological processes, while lab-grown gems are created in controlled laboratory environments using advanced technology that replicates these natural conditions.

In terms of formation, natural gemstones develop slowly under specific heat and pressure, resulting in unique characteristics, including inclusions and variations. Conversely, lab-grown gems can be produced in just weeks, often resulting in stones with fewer imperfections and consistent quality.

When it comes to properties, both types can exhibit similar physical and chemical characteristics, making them nearly indistinguishable to the naked eye. However, lab-grown gems typically lack the unique inclusions found in natural stones, which can be important for collectors.

Ultimately, while both natural and lab-grown gemstones are beautiful and valuable, their origins and formation processes significantly influence their market value and desirability. Understanding these differences can help consumers make informed choices based on personal preferences and values.


How does the Old European Cut differ from modern diamond cuts?

The Old European Cut and modern diamond cuts, particularly the Round Brilliant Cut, differ significantly in their design, craftsmanship, and the visual effects they produce.

Key Differences

Facets and Symmetry: The Old European Cut typically features around 58 facets, which are larger and more irregularly shaped. This results in a chunkier appearance and less precise symmetry compared to modern cuts.

Crown and Pavilion: Old European cuts have a higher crown and deeper pavilion. This design enhances the stone's ability to display 

Aesthetic Appeal: The Old European Cut is celebrated for its vintage charm and romantic allure, often producing a softer glow that appeals to those who appreciate antique jewelry.

Craftsmanship: Old European cuts were hand-crafted, resulting in unique variations between stones. This artisanal quality adds character but can also lead to slight imperfections.

These differences highlight how the Old European Cut embodies historical craftsmanship while modern cuts prioritize light performance and symmetry.
