Description

A cross pendant built on serious stone weight. Vivid blue sapphires totaling 2.20 Cts are set alongside 1.30 Cts of round lab grown diamonds in D Color and VS1 Clarity, all within a solid 14K gold cross measuring over an inch tall. The result is a piece with real presence and real meaning.

Both the sapphires and diamonds are lab grown, real stones, not simulants, not cubic zirconia. Grown with the same chemical and optical properties as their mined counterparts, and handset in our New York City studio in the Diamond District. Sold direct from the maker, so the investment goes into the stones, not a retail margin.

Wear it daily, give it as a confirmation or christening gift, or pass it down. Crosses this well-made are built to last generations.

Shipping & Returns

Diamond certification

Individual diamonds under 1.00 ct are not individually IGI certified. Total carat weight does not determine whether a grading report is included. Contact us to confirm the documents supplied with this piece.

Why are they more affordable?

Because the diamond is grown in weeks rather than mined over millennia, and we sell direct, you get the same beauty, certification, and durability for a fraction of the price of a comparable mined diamond.

How do I care for my diamonds?

Clean gently with warm water, a drop of mild soap, and a soft brush, then pat dry. Store each piece separately to avoid scratching. Reach out any time if you have questions about care.

★★★★★ Martha SparksVerified buyer

Beautiful pendant. Receive many compliments. Thanks

★★★★★ Travis Ála

Working with Oren at Zack and Elle was the best decision I made in this entire process. I came in knowing what she meant to me and very little about what I was actually looking for. Oren never once made me feel rushed or sold to. He asked better questions than I knew to ask, taught me what actually mattered versus what just sounds impressive, and helped me find a ring that fit her exactly. The craftsmanship speaks for itself, but what stood out even more was the care. No pressure, no games, no upselling. She said yes. The ring is stunning and she has not stopped looking at it.

★★★★★ Will Kneeland

I wanted to buy my wife an upgrade to her wedding ring set after fourteen years. Beautiful ring and matching band. Picture doesn’t do it justice. I was a little tentative about ordering a ring online, but the process was easy and my wife and I couldn’t be happier. The ring is stunning, the diamonds are top notch quality (D color on center 3ct stone), and I wouldn’t hesitate for a second to buy another diamond set from them.

★★★★★ Jack Quinlan

Absolutely wonderful company to deal with. Oren provided elite service and a great price on a 4.25ct diamond ring. I would-will definitely buy from them again. Five stars all the way!

★★★★★ Amy Hohon

I bought from them and found the size was too small (by my own fault) and the diamond was loose in the setting. Contacted them and within minutes got a response and they were more than accommodating with fixing the setting and resizing my ring. I can’t say enough about how great the communication is. Highly recommend and will buy from them again. The setting is gorgeous.

★★★★★ virginia dowd

Working with Zack and Elle Diamonds was a complete pleasure. My eternity band is beyond what I expected. The quality and detail are amazing and communication with the owners was second to none!

★★★★★ yvonne laiVerified buyer

Love my ring! Way beyond my expectations. Hope to do another purchase soon.

★★★★★ Nachliel Pokroy

Great service, did a beautiful custom job, Highly recommend

★★★★★ Jamin Butcher

I purchased a pair of 6ct lab grown diamond stud earrings for my wife for our 10th anniversary, completely sight unseen through the Zack & Elle website, and we could not be happier. I originally ordered the earrings with screw backs, but the posts did not work well with my wife’s ears. Oren personally called me to discuss our options, and we sent them back to have them reset with jumbo push backs. The entire process could not have gone more smoothly. The quality of the diamonds, the craftsmanship, and especially the customer service exceeded our expectations.

★★★★★ Bruce Miller

Lab grown solitaire diamond earrings, 14K white gold four prong basket with screw on backs, 3.05 CTTW, D color, VS1, IGI. For $995 you're getting a great pair of earrings and photos don't do these earrings justice. Before I found Zack & Elle other stores wanted $1400+ and those were for F color 10K gold push backs.

★★★★★ Hiep Le

Bought 4 pairs 4 carats diamonds earrings, 4 prongs Martini setting, screw back, in Platinum. Oren is a great guy, always keep me informed even when he was on a trip, the shop’s staff was great… all thumbs up.

★★★★★ Jose Egas

Just got the studs, looking amazing. Great service, Oren was very helpful. Thanks

★★★★★ Geoffrey Doster

Oren did an amazing job. I was nervous at first as I live in another state but he was able to walk me through the process and it was one of the easiest and quickest I have ever done. I will be a repeat customer.

★★★★★ Daniel Cunningham

Have made several purchases through Zack and Elle's and it's hard to imagine going anywhere else. The service provided is incredible and the jewelry is stunning. I'm a repeat customer for a reason and will continue going back!

★★★★★ Ebony SmithVerified buyer
