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 ensures a professional and systematic approach to our business. And it means we excel where it counts the most:

  Assured Product Safety
    Variety of Selection
    Consistent Supply
    Competitive Prices
    Standardized Grading
    Achievements in Research
    Marketing & Education


Assured Product Safety
Our enhancement process and the diamonds that emerge from it are absolutely safe - and since we only distribute the diamonds we enhance ourselves, we can assure safety of all our products to our customers.

Lotus uses only the most advanced and safest electron-based method of irradiation, which results in no residual radiation. The term irradiation refers to causing change in the atomic structure of a substance, in this case, the diamond, and it does not imply resulting radioactivity. For example, certain food products on the market today have been irradiated. These foods have been altered, but they’re perfectly safe to consume.

We do all our enhancements in strict accordance with US safety standards, the highest in the world today. 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 enhance ourselves. We never buy color-enhanced diamonds from any outside source.
 

A Variety of Selection
We carry a large variety of colors, sizes and shapes at different price points. We pride ourselves at being a one-stop shop to meet all your colored diamond needs.

Colors: Lotus diamonds come in various shades of blue, green, yellow, pink, purple, cognac, red and black.

Sizes: We carry sizes ranging from 0.005 carat to 3 carat, with certain colors available in sizes up to 4-5 carats.

Cuts: We carry all colors in round brilliant cuts and blue, green and yellow in princes cuts. Other fancy shapes are also available in blue, green & yellow in larger sizes.

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.

Certified Colored Diamonds: 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.

Consistent Supply
Our diamonds are consistently produced, stocked and distributed in a wide range of colors, shapes, sizes and price points so you can free your imagination in designing and never worry if the particular diamond you want is available.

Due to our longstanding relationships with globally based diamond cutters, we are always able to procure a steady and timely supply of diamonds – assuring the same consistency and timeliness of supply to our customers.

We always carry large assorted inventories of our diamonds, so you don’t have to. We urge you as our clients to buy only what you need and stock only small inventories of replacement stones. We usually stock those items that we can manufacture repeatedly and consistently, so you can always order the exact sizes, colors and cuts you want - in the quantities you need.
 

Competitive Prices
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 nearly colorless diamonds 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.
 

Standardized Grading
You can easily buy a diamond in a particular color, shade, clarity and cut once. But can your dealer offer you a diamond with those exact specifications a second time? Or a third tim? 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 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.
 

Achievements in Research
Lotus is dedicated to the ongoing research into the color enhancement of diamonds. We frequently adjust the enhancement process in order to achieve the best color results – and we are determined to produce the best color quality in our diamonds consistently and economically.

The key part of the enhancement process is deciding which stones are best suited for which color – and which are most economical to use while achieving the desired quality. 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 pink 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.
 

Marketing & Education
Lotus 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.
