...The jeweler who will be putting the ring together was impressed. You may have a new wholesale customer.

..."Talk about "WOW!". The marquise diamond ring arrived safe and sound but I was not prepared for what I saw... the engagement ring is breathtaking.  It is everything you represented it to be and the setting is exquisite.

Thank you so much for your patience and guidance in helping us with our selection and the great wholesale price."
