Kicking off the holiday season, indeed, Lindsay Lohan [1] took to Instagram to share the news that she is engaged to her boyfriend of two years, Bader Shammas [2]. The first thing you'll notice from the sweet snaps are the smitten couple, cuddling up and beaming, though that new engagement ring is a close second. From the photos, we get a glimpse of the gorgeous diamond ring, which also features a sparkling band.

According to Jenny Luker, president of Platinum Guild International USA, "the ring appears to feature a square, brilliant-cut centre diamond that's approximately five to seven carats with pavé diamonds along a platinum band." (Swoon!) Luker estimates the value of the ring at approximately £150,000.

Join us in wishing the happy couple a big congrats, then get a closer look at the engagement ring here.
