Frequently Bought Together
Complete the set — add the pieces below in one step.Frequently Asked Questions
Is the Alexandrite in this necklace real?
Yes. This necklace is set with a genuine Lab Grown Alexandrite. Lab grown stones share the same chemical composition, crystal structure, and optical properties as their mined counterparts  they are created in a controlled environment rather than extracted from the earth.
What metal is this necklace made in?
This piece is crafted in Sterling Silver. Where more than one metal is offered, use the metal selector above and the images and price update to match your choice.
Can I customise this necklace?
Often, yes. Contact us before ordering and we will confirm what is possible for this design  including alternative metals and a different Alexandrite size.
Do you offer resizing?
Yes. We offer free resizing up to two sizes. Reach out with your order number and we will arrange it.
Is a Heart Alexandrite necklace durable enough for everyday wear?
The Prong setting holds the Heart Alexandrite securely, and every piece is finished for daily wear. We still recommend removing fine jewellery before swimming, showering, or heavy manual work.
How long does shipping take?
Each piece is made to order. Crafting takes 5-7 days, and delivery typically lands 15-17 days after you order. The estimate above is calculated from today's date.
