Lab-created Diamonds

While diamond-growing technology has been around for over five decades, gem-quality results have only been achievable for a few years. There are many reasons to consider a lab-created diamond as an alternative to naturally mined diamonds. Gemesis Diamond Company is proud to offer diamonds in both colorless and fancy yellow colors. Gemesis man-made diamonds are certified by leading gemological institutes and cherished by anyone seeking a truly beautiful, environmentally and socially responsible diamond of high quality, purity and rarity. Each Gemesis diamond is totally unique, just as in nature. Each one takes months to get to the final polished end point and once the rough diamond is created and skillfully cut and polished, it is just as radiant and distinct as one created naturally.

Colorless Diamonds

Remarkable proprietary technology allows Gemesis to offer you a full line of high-quality, colorless lab-created diamonds. We’re proud to introduce this exceptional choice as you search for dazzling earrings, an elegant pendant or a spectacular engagement ring. Gemesis colorless diamonds are all certified as Type IIa, the purest type of diamond, which is extremely rare in nature. Less than two percent of the world’s diamonds are Type IIa. A renowned example is the “Elizabeth Taylor Diamond,” formerly known as the “Krupp Diamond,” a 33.19-carat Type IIa diamond.

Fancy Color Diamonds

Until recently, high-quality, fancy color stones were only available in mined form, which can easily sell for tens of thousands of dollars per carat. Some of the world’s most famous natural diamonds are of fancy color. With exceptional beauty and rarity, these diamonds have been associated with many intriguing figures in history from Louis XIV to Catherine the Great. Gemesis is now able to make fancy color diamonds accessible to today’s fashion-conscious consumers. Available in brilliant yellow and golden yellow hues, these diamonds have all the beauty, quality and color of their mined counterparts at an extremely attractive price.

Environmentally Friendly

As massive diamond mining operations are not in pace with increasing consumer consciousness, Gemesis Diamond Company is proud to offer diamonds grown in a controlled environment, resulting in a smaller carbon footprint and very little overall environmental impact compared to mined diamonds. Gemesis lab-created diamonds are a responsible choice for ecologically conscious consumers.

Guaranteed Conflict-Free

Consumers who aspire to make socially responsible purchasing decisions have concerns related to “conflict” or “blood” diamonds. As Gemesis lab-grown diamonds are origin guaranteed and fully disclosed as lab-created, these concerns are alleviated. Gemesis Diamond Company operates at the highest level of safety standards and fair, humane and ethical labor practices.


Gemesis Diamond Company jewelry is available in 14K and 18K white and yellow gold and select styles are available in platinum. Gold won’t tarnish, rust, or corrode, and though it’s very strong, it is also the most malleable of all metals.

The color of gold is determined by two factors:
  1. The type of metal alloys included in it.
  2. The percentage of each metal alloy.

White Gold

Alloying gold with white metals and plating it with a naturally hard element like rhodium transforms the color of gold from yellow to white. Gemesis fully complies with all federal regulations and international fine jewelry standards for pure metal content in its products. Gemesis maintains gold purities at 75% for 18K, 58.33 for 14K.

Yellow Gold

Gold in its natural form has a warm and rich yellow color, which has been its allure for centuries. Modern jewelry manufacturing techniques add alloys like copper and silver to the gold to make the naturally soft metal harder and durable. Gemesis fully complies with all federal regulations and international fine jewelry standards for pure metal content in its products. Gemesis maintains gold purities at 75% for 18K, 58.33 for 14K.


One of the rarest and most valuable of precious metals, platinum is also extremely strong and durable due to its hardness (twice that of pure gold). Platinum won’t rust, tarnish or corrode. Gemesis fully complies with all federal regulations and international fine jewelry standards for pure metal content in its products. Platinum items are 95% pure.

2014 Golden Globe Awards: Red Carpet Recap

And we’re off! After Sunday night’s 71st annual Golden Globes ceremony in L.A., awards season is officially in full swing. As much as we love seeing our favorite actors and actresses win big, we equally love the fashion! Some of our favorite trends from the first major red carpet of the season include:

  • Splashes of color: Red was definitely the color of the evening, as seen on “12 Years a Slave” newcomer Lupita N’yongo who wore a Ralph Lauren cape dress. Pops of color were also seen in yellow, on Lena Dunham in Zac Posen, and in green, on Reese Witherspoon in Calvin Klein. Sofia Vergara, in black Zac Posen, wowed with an eye-catching turquoise statement necklace.
  • Plunging necklines:  Also in red was “American Hustle’s” Amy Adams, who rocked one of the evening’s other major trends – plunging necklines. Inspired by her film wardrobe, the Best Actress winner wore a 70s-inspired Valentino gown. “The Wolf of Wall Street’s” Margot Robbie – a first-time Golden Globes attendee – also sported a plunging neckline in a white, embellished Gucci number.
  • Unconventional dresses:  Several lovely ladies opted for unique, unconventional dresses for their walks down the red carpet. In one of our favorite looks of the night, Emma Watson donned a backless Dior dress (in red!) worn over a pair of navy cigarette pants. Also opting for an out of the box look was Julia Roberts in a Dolce & Gabbana strapless black dress/white button up shirt combo.

If you’re looking for an easy way to translate these trends into your own wardrobe, look no further than Gemesis! As Sofia Vergara proved, the right jewelry is sometimes all you need.

  • Splashes of color: Pieces in fancy yellow or pink provide just the right dose of color!
  • Plunging necklines:  A pretty pendant is the perfect complement to a deep-V cut!
  • Unconventional dresses:  A unique dress calls for a simple – yet still interesting – jewelry look. The perfect conversation starter? An eco-friendly, conflict-free manmade diamond!

Stay tuned for more red carpet coverage here, as award season continues!

New Year’s Resolutions

Resolutions are to New Year’s, what being thankful is to Thanksgiving. On both occasions, there’s a lot of pressure to list things…things you’re thankful for, things you’d like to do differently in the new year, etc. You were on your own on Thanksgiving Day, but we’ve got you covered for New Year’s Eve!

We’ve put together a list of some of the most popular New Year’s resolutions, for easy reference. When you’re inevitably cornered and asked about the changes you’d like to make in 2014, feel free to utilize any and all of the below:

  1. Lose weight/get healthier
  2. Quit smoking
  3. Learn something new
  4. Volunteer to help others
  5. Save money
  6. Spend more time with my family
  7. Pick up a hobby
  8. Go on a trip
  9. Learn to better manage stress
  10. Go green

We happen to be pretty partial to #10. When going green in 2014, why not start with gorgeous, eco-friendly, manmade diamonds from Gemesis? They’re also origin guaranteed, so they’re conflict-free (no “blood” diamond concerns), and they’re priced more attractively than comparable mined diamonds. And there you’ve gone and crossed #5 off the list, too!

Who said resolutions were so hard to keep? Happy New Year!

Why the Diamond Jubilee Is Better Than Cherries Jubilee

Sixty years is a long time to be on the job, but Queen Elizabeth II has done just that. And how, you might ask, does one celebrate a Diamond Jubilee? Cue the pomp and circumstance, break out the Crown Jewels (Are any those diamonds man-made?) and whip up some cherries jubilee.

Side note:  Cherries jubilee, a dessert made with cherries and liqueur and commonly served over vanilla ice cream, flambé style, was first served at one of Queen Victoria’s Jubilee celebrations. Who knew?

The city of London has been in full-on party mode for the past four days, but sadly, celebrations wrap up today. Back to work tomorrow for everyone, including the Queen! If you missed any of the weekend-long coverage over on CNN, here are some of the highlights:

  • The Thames Diamond Jubilee Pageant featured a 1,000-boat flotilla sailing down the River Thames on Saturday. The Queen, accompanied by the Duke of Edinburgh and other members of the royal family, all traveled via the royal barge. Yes, the royal barge.
  • The star-studded Monday night Concert at Buckingham Palace featured performances by Elton John, Paul McCartney, Annie Lenox and Stevie Wonder, among many others. Rock royalty.
  • A network of more than 4,000 beacons were lit across the U.K. on Monday to mark the Diamond Jubilee, with the Queen lighting the National Beacon outside Buckingham Palace.
  • A National Service of Thanksgiving was held at St. Paul’s Cathedral on Tuesday, followed by an appearance by the Queen and other members of the royal family on the Buckingham Palace balcony, complete with RAF flyover.

You know what? Forget the cherries and vanilla ice cream. It’s time to pop some champagne and really celebrate. Or, in this case…royally celebrate.
