Natural color diamonds, such as the famous Hope Diamond, are exceptionally beautiful, but just as exceptionally rare and expensive – and so, for most of us, sadly out of reach. Entrepreneurs in order to satisfy the 3 A’s – accessibility, affordability & availability invented advanced safe methods of color enhancement.
These days many precious gems – rubies, sapphires, tanzanites, to name a few – are regularly enhanced in their appearance. But unlike those gems, which are treated mainly to hide flaws & imperfections, diamonds are enhanced to satisfy a market demand for the unique marriage of color, brilliance & durability that only diamonds can offer.

In order to impart color to the diamond, Man’s ingenuity replaced the primitive processes of using vegetable dyes with hi-tech processes. Currently, diamonds can be color enhanced using three different processes – Irradiation, HPHT or Coating. It is very important to stress that when done professionally, these processes are entirely safe and permanent. This is specifically the case with Lotus Colors because we employ only the most advanced color enhancement processes, in strict accordance with U.S. safety standards.

After the process, the diamond is as safe and natural as it was before – but with its color potential beautifully realized. What takes nature thousands of years, with today’s safe technology, can be accomplished in hours.

Almost any diamond has either color or color potential, but some diamonds are better to use in the color-enhancement process than others. Selecting the right group of diamonds for a particular color is the hardest part of the process. The key is deciding the efficient combination of raw material and process to yield the best color. This is where Lotus’s long experience and insight – as well as our ongoing research – has translated into producing stones with maximum knowledge and efficiency.

Diamonds are the only gemstones to occur in all 11 color families, and they can potentially assume almost any color – blue, green, red, orange, yellow, pink, purple, brown, gray, black or white.

After color enhancement the diamonds retain their strength, durability and trademark brilliance while attaining their potential in vibrant and permanent colors. If proper care is taken the colors resulting from enhancement are absolutely permanent and will not fade over time.
