You’d go a little Tyson on your big sis (ear biting and all) to secure Nana’s vintage Chanel lariat.

But don’t sweat the sparkly stuff. Thanks to Bella Bead Boutique, you can be a lover, not a fighter.

Tucked away inside The Shops at Willow Bend, the unassuming jewelry boutique tweaks pieces to fit your needs. Take in Mom’s gaudy turquoise necklace, for example, and owner Lala Shrem and her talented team might design (with your consent, of course) two toned-down bracelets with added gemstones from the store’s mix.

Don’t have the cojones to divide and conquer family jewels? The store also sells custom baubles by Shrem and her artists and offers jewelry-making classes twice a month.

So you’ll have something to show when the gloves are off.

Bella Bead Boutique, 6121 West Park Boulevard, Plano (469-366-0008).
