The common symptoms of sleep apnea to be aware of are: - Loud or frequent snoring. - Choking in sleep, gasping. - Pauses in breathing during sleep. - Anxiety. - Morning headaches. - Excessive daytime sleepiness. - Waking up with a dry mouth or sore throat.
For instance, while a one carat (1.0 ct.) good quality emerald may sell for somewhere between $525 and $1,125, a five carat (5.0 ct.) emerald of similar quality could sell for between $7,500 and $15,000 (prices are for comparison only, exact prices vary according to market demand).
They could range anywhere from $2500 to $7200. There is a large difference in price due to other factors such as the symmetry, polish, girdle thickness, and presence of any flourescence. This should give you a good idea though of the range of the cost per carat.
