Squash Blossom necklace

Hello my name is James I have this Squash Blossom necklace and I cannot find who The markings belong to GT does anybody know who that was or is thank you

Do a web search for both Grace Touchine and Gordon Todlena and see if either of them does similar work, or uses initials that look the same.

Here is a Touchine piece that sold on eBay to get you started. https://m.ebay.com/itm/GRACE-TOUCHINE-Old-Pawn-Navajo-Handmade-925-Sterling-Silver-Turquoise-Necklace-J/352257800737?hash=item5204337a21:g:nsAAAOSwlzRaX7W2#vi__app-cvip-panel

The initials of the Touchine piece look similar to me, but I’m not an expert! it’s best to research all possibilities. Perhaps the experts here will recognize this or know of other GTs for you to research.
