Lab Diamonds — Is the Value Shifting?

图片
Diamond gemstones have traditionally symbolized value, status, and rarity. While these gems are often associated with expressions of love, anniversaries, and engagements, others proudly adorn them as fashionable symbols of their success .   In the past, diamonds were exclusively sourced from natural mines, but today, advancements in technology allow for the cultivation of diamonds in specialized laboratory settings. The question arises: how do lab-grown diamonds compare in terms of retaining their value over time? Here's what you need to understand.   FACTORS INFLUENCING DIAMOND VALUE   Throughout history,  diamond gemstones  have served as tangible symbols of prestige and wealth. However, like any other commodity, the monetary worth of diamonds has experienced fluctuations over the years, influenced by various market factors, including supply and demand dynamics.   Similar to precious metals such as gold, silver, and platinum, the value of diamonds is subj...

Lab Grown Colored Diamonds: How Are They Made?

  To create diamonds in a laboratory, experts start with a "seed," which is a very small diamond gemstone. They then employ one of two different processes: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).   In the CVD process, the seed is placed in a plasma reactor chamber where a mixture of carbon-based gases is introduced at low pressure. Microwaves are utilized to heat these gases, creating plasma. As the temperature increases to thousands of degrees, gas molecules start to break up, allowing carbon atoms to bond to the seed, layer by layer.   In the HPHT process, the seed is positioned in a mechanical press, subjecting it to intense temperatures and pressure along with pre-existing carbon. The seed serves as a template for the carbon lattice, shaping the  lab-grown diamond . Within a few days, the gemstone undergoes growth, layer by layer, until it reaches the desired carat weight.   How Do Lab Grown Diamonds Get Their Color? Lab dia...
