Avinash Bajaj

Avinash Bajaj

Designing out of San Francisco, California, Avinash Bajaj is the director and founder behind Costar. Since 1998, Costar has been known for their focus on gem quality and unmatched design symmetry. Each engagement ring, anniversary band, and eternity ring from Costar balances global inspiration and modern femininity, utilizing impeccable diamonds and sapphires, as well as lesser-used birthstones like pink tourmaline, natural alexandrite, tanzanite, natural blue zircon, and aquamarine.

Combined with unmatched intricate detail and warm elegance, the work of Avinash Bajaj is a great way to change the "flavor" of a solitaire, or build a beautiful stack.

Most impressively and importantly, Avinash has built his business based on flexibility and service. Most styles are available in many different precious metals, and set with a wide variety of gemstones. Even bespoke products are possible...if the other ten thousand possible combinations don't quite work for you!
