These days we are all intrigued by rare. We want to be different. Express our love in a unique way. When buying the gift of fine jewelry that is rare, unique or different you need a “real” jeweler. Over fifty years ago Joe Costello founded Costello Jewelry Company in Chicago with the mantra of Costello Jewelry Company is a “real” jeweler. They have a staff of well trained and experienced craftsmen, a team of GIA certified Gemologists and customer service associates who are sincere and truly desire to meet your jewelry needs. Find something rare for your loved one with the “real” Costello Jewelry Company of Chicago, our Coast Diamond Retailer of the Week.

Rare Paraiba

A Paraiba tourmaline is instantly recognized by its rare glow that radiates from the inside out. It was discovered in Paraiba, Brazil about 30 years ago and more recently in Mozambique and Nigeria, making them more accessible to you. They are hand-mined so as to protect the stone from damage. Larger Paraiba gemstones are rarer and thus extremely costly per carat. The Coast 5.20 CT oval Paraiba ring in our featured image is surrounded by diamonds and set in platinum (LSK10101-PAR).

The Paraiba is the perfect gift for a love that is rare.
