The blue diamond belongs to the family of fancy-colored diamonds, and its color varies from teal green to peacock blue to steel grey. They are coveted by people because of their gorgeous appeal. Recently, there has been a surge in demand for blue diamond engagement rings. So, most online, as well as brick-and-mortar jewelry stores began offering them. That said, their color can be either natural or due to blue treatment in a lab, and this affects its value. Paragraphs that follow discuss tips for purchasing the best blue diamond.
Natural Blue Diamonds
Natural blue diamonds are rare, and hence, they are expensive. Boron present in the crystal lattice gives these beauties their hue. Keep in mind that even extremely light-hued blue diamonds are more expensive than colorless diamonds with similar physical qualities. Above all, the Hope Diamond in the Smithsonian Museum is the most famous blue diamond in the world.
Blue Diamond Engagement Rings
The blue diamonds used in most engagement rings that are sold today are lab-treated. The two most common types of blue diamonds used in rings are lab blues and treated blues. Remember that most of the regular folks cannot afford rare and natural blue diamonds in their diamond rings because of their extremely high price tag.
Treated And Lab-Grown Blue Diamonds Are Affordable
Treated blue diamonds are initially white diamonds with a warmer hue, which are not preferred by those looking for colorless diamonds. These diamonds are picked by gem scientists and are given blue color by irradiating them. For this, they use a special machine that converts the color of the outermost surface of the stone. This results in permanent and brilliant turquoise blue.
Lab blues are made from scratch in laboratories, and because of this, they are cheaper than treated blues. Their specialty is that they have the visual qualities and chemical properties of natural blue diamonds. Besides, they are made by placing natural diamond seed crystals inside a chamber filled with gases. The blue color is imparted by adding boron into this setup. Once the device is all set, the elements are heated inside the chamber, and the layers of the blue diamond begin to grow.
Lab Blues With The Properties Of Natural Blues
The lab blues are produced in a controlled environment inside labs, and because of this, they have all the properties of natural blues.
These are the important points that you must know before buying blue diamond engagement rings, and we hope that the details shared above were useful for you.
