I gave my wife a beautiful 3 carat heart diamond necklace from Astrea for Christmas. It is stunning and she is yet to take it off! We could not be more delighted with our purchase and love the brand! We will be coming back for more!

Everything from my first reach out to receiving my ring was seamless. No question was unanswered and the guidance in design was like no other. Astrea took time to really understand my needs so the end product was just incredible. Every time I wear my ring I get comments. The intricate detail, the sparkle and the customer experience has me never shopping for diamonds anywhere else.

After reviewing the quality of lab diamonds, my husband bought me a stunning bracelet and necklace. Both pieces are absolutely gorgeous and I couldn’t be happier. I’m really impressed and highly recommend Astrea

I was delighted to acquire a lab-grown diamond tennis bracelet from Astrea, and the experience was extraordinary. They are sustainable and sophisticated. The brilliance of my tennis bracelet is also incredible and it comes with all the certification. For those looking for exquisite, sustainable jewellery, Astrea is the one. An absolute gem of a find!
