History & Symbolism
The tennis necklace, originally called the "eternity" or "line" necklace, gained widespread recognition in the 1980s during a Grand Slam tennis match. Its continuous row of diamonds represents unity, strength, and timeless elegance. With lab-grown diamonds, this classic design now reflects modern values of sustainability and innovation while maintaining its iconic style.

Certification & Made-to-Order
Handcrafted to order. The carat weight of your center stone is shown in the title and details above. A center or solitaire diamond over 0.50 ct includes its own IGI certificate (natural over 0.30 ct, GIA); colored gemstone centers and the smaller hand-matched accent diamonds (pavé, halo, eternity, and tennis) are not individually certified, as is standard in fine jewelry — what is listed is their carat or total carat weight. Every Irdoja diamond is graded to our D–E color, VS–VVS clarity, Excellent-cut standard, and any certificates accompany your finished piece.
Every Irdoja piece is handcrafted to order — please allow 3–4 weeks for production (up to 4–6 weeks for custom designs).
Shipping is complimentary and fully insured on every order, with no minimum. Your piece ships via insured carrier with signature required for security, and most U.S. deliveries arrive within 2–5 business days once it leaves us — with a tracking number emailed the moment it ships.
