OREM — If diamonds really are a girl's best friend, then that circle of friends is expanding to include pink, purple and yellow precious stones.

But for those who can't afford the naturally vibrant gems flashed by Jennifer Lopez and Katie Holmes, an Orem company has found a way to "enhance" real diamonds to make them every bit as sparkly as J.Lo's 14.5 carat blue diamond, minus the six-figure price tag.

Suncrest Diamonds, a division of US Synthetic, is one of the few companies in the world that use pressure and heat to change an authentic diamond's color — not just disguise it in a coat of paint.

"If you are a celebrity, (you) can afford these outrageous prices for these diamonds," said Marc Modersitzki, director of marketing for US Synthetic in Orem, the parent company of Suncrest Diamonds. "Now we have (diamonds) ... as beautiful as the rare ones you see the celebrities going after, and we can offer them to the general public."

A natural pink diamond can cost nearly 25 times more than its colorless counterpart, and a yellow diamond can be 15 times more expensive.

But a diamond that became pink through Suncrest's "Sundance" procedure will cost only three to four times more than a white diamond.

The glittering trend in Hollywood has seen Ben Affleck, now an ex-fiance, proposing to Lopez with a 6.1-carat pink diamond and Marc Anthony, J. Lo's current husband, adding a 14.5-carat blue diamond ring to her collection.

Tom Cruise proposed to Holmes with a yellow diamond, and Kobe Bryant of the Lakers bought an 8-carat $4 million purple diamond ring for his wife, Vanessa.

"Colored diamonds are the most popular fashion jewelry today," said Russ Myers, division manager at Suncrest Diamonds. "Most fashion jewelry uses a lot of it."

But creating copycat styles the average jewelry consumer could afford meant using painted or tinted diamonds, diamonds that often lost their color if the metal around them had to be heated or adjusted.

So, wanting to capitalize on the trend, diamond wholesalers contacted US Synthetic, a company whose employees have been diamond experts for decades.

Suncrest Diamonds processes nearly 1,000 carats a week now, weighing, measuring and assigning bar codes to each diamond.

Using infrared technology, the diamonds are then scanned for certain naturally occurring chemicals. If a diamond shows signs of boron, it's highly likely it has the potential to become a blue diamond. With nitrogen, it will become a yellow stone.

"We put in the effort to figure out what's going on before the stone's processed," Myers said. "When you're dealing with diamonds, surprises aren't a good thing."
