Understand your materials
Lab-Grown Diamonds and Gold Options
Lab-Grown Diamonds
Specialists grow lab diamonds under controlled conditions using technology that recreates the environment in which diamond crystals form. With a lab-grown diamond, you receive the same carbon crystal structure, hardness and optical properties associated with a mined diamond.
Miners recover natural diamonds from geological deposits. Gemologists use specialist equipment and records to determine whether a stone has a mined or laboratory origin.
Compare diamonds through the 4Cs
Cut
The proportions and finish that affect light return
Colour
The amount of visible colour within the stone
Clarity
The type, size and position of internal or surface features
Carat
The weight of the diamond
Ask to review the grading report when one accompanies your chosen stone. Check the report number, measurements, grades and laboratory name. Our team can explain each part during your consultation.
A set budget can produce different combinations of carat, colour and clarity. Compare complete stones rather than choosing from one grade alone. A well-cut diamond can give you strong light performance without the highest grade in each category.
18K Gold
Jewellers make 18K gold by combining 18 parts pure gold with six parts alloy metals. You receive 75% gold content with added strength for settings and jewellery that faces frequent wear.
The alloy composition influences colour. You can choose yellow, white or rose tones where the design permits.
24K Gold
You receive the highest standard gold content used in jewellery with 24K gold. It has a rich yellow colour and greater softness than 18K gold, so the design and intended use require care.
We specialise in pieces that combine 18K and 24K gold. During your consultation, we discuss construction, wear and care before you choose your metal.
Use the UK hallmark and written product description to confirm the stated metal fineness where hallmarking law applies. Ask our team to explain the marks on your chosen piece.
