Ditto, the size is perfect on you! It''s really lovely! However, the issues of the softness of the stone is a concern, so I would insure the ring in case a chip happens. Luckily it''s a round, so it woudn''t be a huge issue finding a replacement or getting one cut should something happen.
and welcome! Don''t be shy, you''re amongst fellow jewellery nuts here!
Love your Morganite and the proportions are just right. I don''t think it looks too big - it really suits your hand. As has been mentioned it''s not the hardest of gemstones so needs a bit of care but you should enjoy wearing it.
I''d love to wear Morganite and Kunzite more but unfortunately I''ve found I''m Morganite coloured and it gets lost on me!
