Lab-grown sapphires can be produced in various colors, such as blue, pink, yellow, green, purple and even colorless (white). 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.


What makes the marquise cut unique compared to other shapes?

The Marquise Cut is a distinctive diamond shape that stands out from other cuts due to its unique characteristics and visual effects. Here are the key features that make the marquise cut unique:

Distinctive Shape

The marquise cut features an elongated, elliptical shape with pointed ends resembling a boat or an eye. This design creates an elegant and dramatic silhouette that can enhance the appearance of the wearer's finger, making it look longer and slimmer.

Brilliance and Sparkle

Typically having around 58 facets, the marquise cut is designed to maximize light reflection and refraction. Its unique facet arrangement allows it to produce a striking brilliance, although it may not sparkle as intensely as the Round Brilliant Cut. The pointed ends and curved middle help channel light through the diamond, creating a captivating display of fire.

Illusion of Size

One of the most appealing aspects of the marquise cut is its ability to create the illusion of a larger stone. Due to its elongated shape, it covers more surface area than other cuts of the same carat weight, making it appear bigger and more impressive.

Symmetry and Craftsmanship

The symmetry of a marquise cut is crucial; both ends should align perfectly to maintain its aesthetic appeal. This requirement for precision makes well-cut marquise diamonds particularly sought after, as even slight asymmetries can detract from their beauty.

Historical and Romantic Appeal

Originating in the 18th century, the marquise cut was reportedly commissioned by King Louis XV for his mistress, adding a layer of romantic history that enhances its allure. This vintage charm makes it a popular choice for those looking for something unique and timeless.

Overall, the marquise cut combines elegance, brilliance, and historical significance, making it a favored choice for those seeking an eye-catching and distinctive gemstone.
