I think more couples should consider custom manufacturing - it's affordable, not mass produced and all of the diamonds Grace Diamonds deal with are certified conflict free! (Melanie Murphy is an author and her YouTube videos have amassed more than sixty million views online.)

“My partner Thomas and I are so happy that we decided to design an engagement ring and custom wedding band(s)
with Grace Diamonds, instead of going the more traditional route and having him choose something from a
shop! The resulting piece(s) are so unique and are inspired by old, vintage target rings I adored but that were just far too expensive
for us. Grace Diamonds were able to work with our budget to create a modern take on an old, Art Deco
style of jewellery that included a couple of small diamonds from my mother’s engagement ring (which was passed down to me),
and a pop of red (rubies. Working with Grace Diamonds was smooth sailing all
the way; Gráinne responded really quickly to e-mails, she listened to every bit of input from us throughout the whole journey of
creating the rings and always offered up solutions to ensure we’d be happy customers. I’ve been shouting about them from
the rooftops because I think more couples should consider custom manufacturing – it’s affordable, not mass produced
and all of the diamonds Grace Diamonds deal with are certified conflict free! Absolutely chuffed with the finished result and delighted to
have had Gráinne be part of our story – she’s so passionate about what she does, and it truly shows in her work!”
