Lab-Grown Colored Sapphire Gemstones for Jewelry/Horology
Sapphire (Sapphire) belongs to the corundum mineral family, primarily composed of aluminum oxide (Al₂O₃). Trace elements such as iron (Fe) and titanium (Ti) impart diverse colors excluding red, including cornflower blue, royal blue, padparadscha (pinkish-orange), yellow, and green. With a Mohs hardness of 9 (second only to diamond), a refractive index of 1.76–1.77, high transparency (80% transmittance in the 400–4000 nm wavelength range), and exceptional chemical stability (resistant to acid/alkali corrosion), sapphire exhibits a melting point of 2050°C. Natural sapphire crystals often contain inclusions such as rutile and zircon, forming unique asterism (star effect) or color-change phenomena.

1. Q: What colors do sapphires come in?
A: Sapphires (part of the corundum family) exhibit a range of colors including blue, pink, yellow, green, and purple. Among these, Cornflower Blue, Royal Blue, and Padparadscha (pink-orange) are particularly prized for their rarity and unique aesthetic appeal.
2. Q: How to distinguish real sapphires from fakes?
A: Natural sapphires typically contain rutile needle-like inclusions and have a Mohs hardness of 9 (can scratch glass). Synthetic sapphires often display uniform coloration and lack natural inclusions. Verification through professional gemological certificates is recommended.
