jennymcJenny McCarthy is definitely not one to shy away from media! She shocked over 3 million viewers last Wednesday on live television via her morning talk show, The View by showing off a huge yellow sapphire and diamond ring and announcing her recent engagement to singer Donnie Wahlberg.

The former model, actress, one-time author and current co-host of The View was immeasurably ecstatic, jumping up and hugging co-hosts Barbara Walters and Sherri Shepherd. A slideshow of pictures of the happy couple played across the screen as Wahlberg made a surprise appearance from backstage, coming up to hug his sweetheart.

McCarthy’s bubbly and vivacious personality seems to match her engagement ring perfectly: a square brilliant cut yellow sapphire, surrounded by a halo of white diamonds set in a split shank pave white gold band. Known to be a spiritual person, she may have chosen a bright yellow stone to elicit inspiration, creativity, and optimism.jennymc

The actress and TV personality describes how Wahlberg had enlisted the help of her 11-year-old son, Evan, with the proposal. While sitting on the couch at their shared home, Evan brought out a card that said “Will” and handed it to her. He walked back into the other room, coming back with “You”. He returned a third time with a card meant to say “Marry” but spelled “Mary”. McCarthy was in laughter and tears before Donnie came out the last time, wearing a shirt imprinted, “Me?” and got down on one knee.

“Of course, I said ‘Yes,'” she related. “In that moment Evan yelled, ‘I have another dad!’ and it made all of us cry.”

McCarthy began dating the New Kids on The Block singer in May of last year. The pair plan to tie the knot sometime in August 2015.

Sapphire HeatSapphires come in every colour except a certain shade of red called a ruby. There are several different methods to enhance and improve the colour and clarity of a sapphire. Commonly practiced treatments are heating a natural sapphire to heighten the look of the stone. Heating a sapphire is done by placing it in a furnace at temperatures between 500 and 1800°C for several hours.  Another way is by heating it in a nitrogen-deficient atmosphere oven for seven days or more. With this process the stones become bluer and lose some of their inclusions like the silk kind. When higher temperatures are used the stone loses all silk inclusions and under magnification the stone is clear. Sapphire and other gemstones being heat treated goes back to Roman times. An untreated natural stone is somewhat rare and will be sold with a certificate from a gemology lab.

Another treatment is diffusion to add impurities to the sapphire and enhance the colour. A type of chemical element called beryllium is diffused into the sapphire with very high heat. Many colours of sapphires are being treated with beryllium. At first orange sapphires were created with this process but now the process has been advanced and many different colours can be produced.

Sapphire Heat

On the other hand a type of sapphire called “Yogo” sometimes does not need to be heat treated because of their natural cornflower blue colour. These sapphires have a deep blue uniform clarity and are generally free of any characteristics or inclusions. Intergem Limited started marketing the Yogos in the 1980’s as the world’s only untreated sapphire guaranteed. By 1982 heat treatment became a major issue at that time 95% of all the worlds sapphires were being heated to bring out their natural colour. The guarantee of Intergems marketing of Yogos set them apart of many in the gem industry. The issue ended up on front page of the Wall Street Journal in 1984 with the headline “Sapphire Marketer Upsets the Gem Industry.”

How to tell if your sapphire has been heat treated? Usually a small UV lamp can help check the gem quickly for any potential alterations. Any stones that have a chalky florescence are most likely heat treated. Taking it to a certified gem dealer with GIA industry standards is a good way to have them test it.
