Why Buy From Us?

Excelling Where It Counts

Lotus’s many years of involvement in manufacturing and selling both natural color gemstones and white diamonds has given us the edge in the colored diamond industry. The global scope of our operation and the use of specialists for every task ensure a professional and systematic approach to our business. And it means we excel where it counts the most :

Our enhancement processes and the diamonds that emerge from it are absolutely safe. LOTUS COLORS, INC. uses only the most advanced and safest electron-based method of irradiation in strict accordance with US safety standards, which results in no residual radiation. After enhancement, we always check the safety of our stones with an in-house Geiger counter. We also follow a strict policy of distributing only the diamonds we irradiate in the U.S. We never buy any irradiated color enhanced diamonds from any outside source.


COLORed DIAMONDS are ideal for the global market. Their regular supply allows attractive and fashionable jewelry to be created at affordable prices. It also enables the gems to be featured in catalogues, allowing clients to buy add-ons to match existing pieces of jewelry.

However, not every manufacturer of COLORed DIAMONDS can guarantee the consistency of supply and color quality that Lotus can.


You can easily buy a diamond in a particular color, shade, clarity and cut once. But can your supplier offer you a diamond with those exact specifications a second time? Or a third time? If it’s not Lotus, don’t count on it.

Our use of a standardized system to grade our diamonds means that each diamond you buy from us has been carefully categorized, and further stock of that specific type of diamond either exists or can be created. If you feature any of our diamonds in your product line, LOTUS COLORS, INC. will be able to restock those very stones consistently according to your needs.

We have staff specializing only in grading our diamonds, and every diamond in each of our global offices has been graded according to one uniform standard.


LOTUS COLORS, INC. offers our clients discounted samplers and memorandum programs, and we provide important information on selling and product presentation. We firmly believe that proper understanding of our product is vital for its successful sale.

We regularly donate our diamonds or sell them at a discount to gemological institutes worldwide, contribute articles to trade publications, and use trade shows, advertising and meetings with clients to promote the value of COLORed DIAMONDS – and encourage safety and integrity in the trade. For instance, we highlight the availability of affordable Geiger counters to check the safety of the gemstones.

This website is another part of this effort. It is not only geared to increase the sales of our product, but intended to provide, first and foremost, accurate and complete information to all our readers.

Price Points
We assort the stones of each color, size and cut by quality to meet different price points. This means we can always provide a range of diamonds, from inexpensive varieties to specialty high-priced items.

We are among the few companies to have started certifying colored enhanced diamonds using established gem labs globally. This helps package our product well and assure consumers about the safety and quality of our product.


Our economies of scale, state-of-the-art technology, efficient manufacturing process, and bulk buying of raw materials allow our products to be very competitively priced.

Buying from the Source - We source most of our raw material directly from our Mumbai office, buying them in bulk, and taking advantage of the best prices available. We also travel to Belgium and Israel to find additional sources for our diamonds.

Experienced, Efficient Manufacturing – Many years of experience, along with our trained staff and ongoing research helps us maintain a high success rate of production and avoid manufacturing stones in murky or otherwise unsellable colors, or damage our stones during enhancement. We always strive to use the least expensive raw materials to produce the best color results using state-of-the-art technology.

Selling on a Global Scale – Our global offices do not cater to only one market, and if particular items do not sell as well in one branch, we can sell it at another, allowing us a quicker turnover of stock and greater flexibility. With our economies of scale, we can keep the costs down, and pass the savings on to you.


LOTUS COLORS, INC. is dedicated to the ongoing research into the color enhancement of diamonds. We are determined to produce the best color quality in our diamonds consistently and economically. The key part of the enhancement process 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.

While some colors are easily duplicated using enhancement, purples and pinks are hard to replicate consistently. A measure of our success is that Lotus was among the first companies to manufacture purple and pink diamonds in commercial quantities, and to date we have one of the largest quantities of those diamonds in stock.

Pink diamonds are the most expensive of all the colors.
