The delightful numerology bracelet is set in 18kt yellow gold and adorned with white sapphires. To find your special numerology, you will need to add your date of birth for the date, month and year separately until you achieved a single digit. For example for a birthdate on the 2nd of january 1972 your numerology calculation is as follows 0 2=2 (date), 0 1=1 (month) and 1 9 7 2=19==> 1 9=10 ==> 1 0=1 (year). You will need to add 2 1 1=4. The bracelet is hallmarked by the london assay office.
