July Babies, It’s not too late! Gather Your Rubies!


The artists that we represent come from around the world, and one thing they all have in common is their love and fascination for gemstones. Happy Birthday all you July babies, this month it’s all about rubies!

One of the four precious stones, rubies lure us in with their colorful energy. Their bright pink and deep red sparkle are truly enchanting. Being in the corundum, or sapphire, family means that you don’t have to feel bound by one shade of color. Sapphires are fair game here, so celebrate your month in the most colorful, gorgeous fashion!

Nicole Landaw Goes Global!

Nicole Landaw’s jewelry is exquisite, to say the very least! We have had Nicole’s bold and ultra glamorous designs on our radar for some time now and are SO thrilled that her Agatha ring was recently featured in Estee Lauder’s global ad for their Pure Envy lipstick campaign!


Model Carolyn Murphy completes her desirable look by adorning her hand with none other than Nicole Landaw’s rutilated quartz Agatha ring! Based in Brooklyn, her small studio has been waiting in the wings for a moment like this!!


We LOVE this double stone ring because of its funky sophisticated look.  What an honor to have such a fabulous piece chosen for this large scale campaign!  Congratulations Nicole!


The golden needle-like rutiles of the Brazilian Quartz make each stone perfectly unique.  However, if you are looking for the same look but with a stronger color palette, this fabulous ring can also be made with tiger’s eye or amethyst – whatever the stone, this ring is sure to make an impression!
(And she makes a matching necklace to boot!)
