I think the matte ball clasp is fine too. Give yourself a break! I mean with all the worrying as to how well you are going to wine and dine your guests, and how fabulous the band/DJ will be, and what with all the other well-thought-out entertainment/decoration you will be indulging your guests in, trust me when I say from experience that nobody will come up to you on that day exclaiming, "My God, that is one AMAZING pearl clasp you have there!!". And you know why? Because they will all be stuffing their faces with fabulous food(in my case everyone was completely taken aback as to how the caterer was able to make tofu taste so good!) while guzzling the fine booze, and doing funny dances till they drop of exhaustion or someone has a near heart attack(Old Uncle Casimir doing his famous Hip Flop moves). Again trust me when I say that even if my maid of honour had stuck a "kick me" sign on my back, no one would have stopped their intense partying to actually notice, let alone actually kick me. When I ask friends now, many years later, what they remember about my wedding---it's the "exotic" vegan food, the abundance of fresh flowers and the weird scared look my husband had on his face before the ceremony.
Why not recycle the matte ball clasp and have hubby get you the clasp of your dreams for your first wedding anniversary(how romantic is that, eh?) You'll have a WHOLE YEAR for devoting to buying, and then casually sending back, all the clasps you've inspected and don't think quite make the cut, until you find THE ONE!! Plus, with the way gold prices are soaring, in a year's time, the matte ball clasp will probably be worth double what you initially paid for it.
Just some thoughts.
