Although this is a very standard, blah looking business, the merchandise choice and quality are excellent. Sabri Guven has showcases full of rings, necklaces, watches, earrings, gold, silver, platinum, diamonds and gemstones. AND, if you don't see what you want, they will make it for you. They are also qualified to do repairs (which you can watch), remountings, engraving and appraisals.
Hint: Be sure to check their website for coupons and/or specials. Right now, they have a coupon for up to 30% off your entire purchase (20% for you + 10% for a friend).
