Quite the difference, right? Well, cubic zirconias don't follow a typical grading system like diamonds do with the 4Cs.Ĭolored gemstones have A to AAA quality. The boule is a colorless sapphire, so scientists can add different minerals to create the different lab created sapphire colors. During the process, aluminum oxide powder is melted with a flame.Īs it's melted, it solidifies into a teardrop shape they called a boule. It was the most cost-effective way and the first one used. In a lab, scientists create sapphires using two different ways: the melting process and the solution process.įlame fusion is a technique used in the melting process. It's much easier to make sure no impurities run into the mineral if it's in a controlled environment like a lab. But as a natural gemstone, impurities infiltrate the mineral more often than not. When no impurities enter the corundum forming, that's what give us white sapphire. Every color of corundum is sapphire, except red. Every colored sapphire comes from the mineral called corundum.Ĭorundum starts colorless, but different impurities cause it to become different colors. And, there’s a right pick for everyone! We can’t wait to help you build your perfect ring.Sapphires come in a rainbow of colors, though most unfamiliar with jewelry only know of blue sapphires, the September birthstone. Of course! Shoot us an email here, or drop us a note here, and we can work with you to find the perfect stone! Both natural and lab sapphires are gorgeous options. Can you help me choose between natural sapphire vs lab created sapphire? On the other hand, diamond (even blue diamonds!) will show rainbow sparkle, too. So, when you choose a blue sapphire, it will sparkle blue, light blue, and white.
And, cut quality is directly responsible for light reflection and sparkle! So, always make sure your stone is bright enough and well cut! Another thing to remember is that sapphire’s sparkle is different than diamond. This is because dark stones do not allow for light reflection as much as medium or light tones do. Yes, blue sapphires that are medium or light tone, eye clean, and well cut, sparkle! However, if your stone is too dark, too included, or poorly cut, it will not shine as much.
