NEW Pick Up Location

  • We have a new pick up location!!  We have partnered with Conversation Peace Jewelers (CP Jewelers) located in the Villages of Five Points shopping center near Weis - between Ocean Grill and China Garden.

Shipping Option

  • Yes, we can ship your order to you.  At this time, we only offer one ship method - USPS - with a flat-rate fee of $8.75.  We cannot ship orders outside of Delaware because we are not set up to handle sales tax remissions to all 50 states and hundreds of localities.  Sorry for any inconvenience.  We hope you understand.

Order Processing Time

  • We require 1 business day to prepare your order.

Gift Cards

  • Digital Cards - If you have a digital gift card that you received via email, it will work in the store just fine. 

  • Physical Cards - If you have a physical gift card (blue card with a magnetic strip), please email us at info@greatstem.com with the card number (back of the card, far right, under the strip).  We will convert it to a digital card that will work in the store.
