4-Claw Classic Diamond Tennis Necklace Half Eternity 21.50ct TW 40cm/15.7in
Lab vs Natural Diamonds
Both are real diamonds — same chemical structure, same sparkle. The difference is origin.
- Natural Diamonds — Formed over billions of years deep within the earth. Rarer, with each stone unique. Typically carries higher resale value.
- Lab-Grown Diamonds — Created in weeks using advanced technology that replicates natural diamond growth. Chemically, physically, and optically identical to natural diamonds. More affordable, letting you choose a larger carat size for the same budget.
Which is right for you?
- Want tradition, rarity, and investment value? Choose Natural.
- Want maximum size/clarity for your budget, with the same brilliance? Choose Lab-Grown.
Both meet SH Bright White standards — every stone, natural or lab grown, is hand-selected for brilliance, fire and sparkle.
Diamond Information
SH Jewellery deals mostly in the whitest D/E/F colour grade diamonds. Each diamond is carefully crafted to produce the finest sparkle and brilliance.
Centre diamond quality:
Natural Diamonds: GIA certified, D-E colour, SI1-SI2 clarity — the whitest colour, with slight inclusions difficult to notice without a microscope.
Lab Grown Diamonds: IGI certified, D colour, VVS2 clarity — exceptional whiteness with virtually no visible inclusions.
Side diamond quality:
Side diamonds (e.g. smaller diamonds in the bands) and diamond wedding bands share the same quality standard. Since a wedding band has no centre stone, this applies to every stone in the band.
- Natural: E-F colour, SI1 clarity — superior whiteness, with slight inclusions only noticeable under a microscope.
- Lab Grown: D colour, VVS2 clarity
All diamonds are hand selected for superior brightness and sparkle.
Prices are subject to change based on availability and market conditions. If you have specific requirements outside these parameters, please send us an enquiry and one of our staff members will assist you in finding the right diamond.
