Lab Grown Sapphires
Created with Care, Never Mined
Our beautifully created sapphires share the same physical, chemical, and optical properties as traditional sapphires, offering a rich, radiant blue color. Sapphires belong to the corundum family, and the term “sapphire” can refer to any corundum gemstone that is not red enough to be classified as a ruby. While classic sapphires are best known for their pure blue appearance, their tones can range from slightly greenish blue to violet-blue.
The corundum family also includes rarer varieties known as “fancy sapphires,” which appear in colors such as violet, green, yellow, orange, pink, and purple. Parti-colored sapphires are another unique type, displaying two or more colors within a single stone. Some sapphires may even shift in color under different lighting, while others can appear in softer gray, black, brown, or muted tones.
Lab-grown sapphires can be created through several advanced methods. One common technique is flame fusion, where powdered materials pass through an intense flame, melt, and crystallize on a rotating base. Another method is flux growth, a slower and more costly process that can produce stones closely resembling natural sapphires. In this process, a molten flux dissolves the necessary materials, and as the solution gradually cools, sapphire crystals begin to form.

Mohs Hardness Scale
The Mohs hardness scale ranks gemstones from 1 to 10 based on their resistance to wear and scratching. With a rating of 9, sapphires are naturally strong and highly durable, making them resistant to scratches, chips, cracks, and everyday abrasion.
Sapphire Care & Maintenance
Proper care helps preserve the beauty and quality of your sapphire. Because sapphires are highly durable, they are generally simple to maintain at home.
Durability & Hardness
The Mohs scale measures how resistant a gemstone or mineral is to scratching. Rated 9 on the Mohs scale, sapphires are exceptionally strong and can usually handle the demands of daily wear. This makes them an excellent choice for everyday jewelry, including rings and other frequently worn settings.
Stability & Wearability
Sapphires are highly stable gemstones, making them suitable for regular wear. They are resistant to heat, light, and many common chemicals that may affect softer stones.
Durability & Hardness
Warm water with mild soap is a safe and effective way to clean sapphire jewelry. Untreated, heat-treated, and lattice-diffusion-treated sapphires can often be cleaned with ultrasonic or steam cleaners.
Durability & Hardness
Untreated and heat-treated sapphires are known for their strong durability. However, sapphires treated through lattice diffusion may vary in how deeply the color penetrates the stone. If the color layer is shallow, the gemstone may be more vulnerable to surface wear or damage during re-cutting. Fracture-filled sapphires may contain high-lead glass filler, making them more sensitive to acidic substances like lemon juice and other chemicals. Stones with significant glass filling require extra care compared with untreated, heat-treated, or lattice-diffusion-treated sapphires.
